The September 11 attacks were carried out by 19 hijackers of the Islamist militant organization al-Qaeda. In the 1990s, al-Qaeda leader Osama bin Laden declared a militant jihad against the United States, and issued two fatawa in 1996 and 1998.[1] In the 1996 fatawa, he quoted the Sword Verse. In both of these fatawa, Bin Laden sharply criticized the financial contributions of the American government to the Saudi royal family as well as American military intervention in the Arab world.[2]

These motivations were published in Bin Laden's November 2002 Letter to the American people,[3][4] in which he said that al-Qaeda's motives for the attacks included Western support for attacking Muslims in Somalia, supporting Russian atrocities against Muslims in Chechnya, supporting the Indian oppression against Muslims in Kashmir, condoning the 1982 massacres in Lebanon, the presence of US troops in Saudi Arabia,[4][5][6] US support of Israel,[7][8] and sanctions against Iraq.[9] Bin Laden and Ayman al-Zawahiri asserted that Israeli repression of Palestinians during the Second Intifada was the immediate cause that forced Al-Qaeda to launch the September 11 attacks.[10][11][12]

Following the attacks, the Bush administration asserted that al-Qaeda attacked the United States because "they hate us for our freedoms". George W. Bush said in a speech to Congress nine days after the attacks that "They hate what we see right here in this chamber — a democratically elected government. Their leaders are self-appointed. They hate our freedoms — our freedom of religion, our freedom of speech, our freedom to vote and assemble and disagree with each other."[13] Al-Qaeda leadership maintained that United States was targeted in retaliation for its imperialist aggression against the Muslim world. In a speech released in 2004, Osama Bin Laden stated: "free men do not forfeit their security, contrary to Bush’s claim that we hate freedom. If so, then let him explain to us why we don’t strike for example – Sweden?"[14][15][16]

Before the attacks, Al-Qaeda issued proclamations that provide insight into the motivations for the attacks: one was the fatwā of August 1996,[17] and a second was a shorter fatwā in February 1998.[18] Both documents appeared initially in the Arabic-language London newspaper Al-Quds Al-Arabi. Bin Laden's 1998 fatwā stated:

"The ruling to kill the Americans and their allies -- civilians and military -- is an individual duty for every Muslim who can do it in any country in which it is possible to do it, in order to liberate the al-Aqsa Mosque and the holy mosque [Mecca] from their grip, and in order for their armies to move out of all the lands of Islam, defeated and unable to threaten any Muslim. This is in accordance with the words of Almighty God, "and fight the pagans all together as they fight you all together," and "fight them until there is no more tumult or oppression, and there prevail justice and faith in God.""[4]

The fatwā also denounced the presence of US troops in Saudi Arabia and asserted that Americans were attempting to balkanize and destabilize the Arab world with the intent of guaranteeing "Israel's survival":[3][4]

"..for over seven years the United States has been occupying the lands of Islam in the holiest of places, the Arabian Peninsula, plundering its riches, dictating to its rulers, humiliating its people, terrorizing its neighbors, and turning its bases in the Peninsula into a spearhead through which to fight the neighboring Muslim peoples."[19][20]

After the attacks, bin Laden and Ayman al-Zawahiri published dozens of video tapes and audio tapes, many describing the motivations for the attacks. Two particularly important publications were bin Laden's 2002 Letter to the American people,[21][22] and a 2004 video tape by bin Laden.[23] In addition to direct pronouncements by bin Laden and Al-Qaeda, numerous political analysts have postulated motivations for the attacks.

Stated motives

[edit]

Support of Israel by United States

[edit]

Further information: Arab–Israeli conflict and United Nations Partition Plan for Palestine

In his Letter to the American people, bin Laden described the United States' support of Israel as a motivation:

The expansion of Israel is one of the greatest crimes, and you are the leaders of its criminals. And of course there is no need to explain and prove the degree of American support for Israel. The creation of Israel is a crime which must be erased. Each and every person whose hands have become polluted in the contribution towards this crime must pay its price, and pay for it heavily.[24][25]

In 2004 and 2010, bin Laden again repeated the connection between the September 11 attacks and the support of Israel by the United States.[26][27] Support of Israel was also mentioned before the attack in the 1998 Al-Qaeda fatwā:

[T]he aim [of the United States] is also to serve the Jews' petty state and divert attention from its occupation of Jerusalem and murder of Muslims there. The best proof of this is their eagerness to destroy Iraq, the strongest neighboring Arab state, and their endeavor to fragment all the states of the region such as Iraq, Saudi Arabia, Egypt, and Sudan into paper statelets and through their disunion and weakness to guarantee Israel's survival and the continuation of the brutal crusade occupation of the Peninsula.[4]

Bin Laden's strategy to expand Al-Aqsa Intifada

[edit]
Main article: Al-Aqsa Intifada

The blood pouring out of Palestine must be equally revenged. You must know that the Palestinians do not cry alone; their women are not widowed alone; their sons are not orphaned alone... With your help and under your protection, the Israelis are planning to destroy the Al-Aqsa mosque. Under the protection of your weapons, Sharon entered the Al-Aqsa mosque, to pollute it as a preparation to capture and destroy it.

— Osama bin Laden's "Letter to the American people" (2002)[28][29]

The eruption of Al-Aqsa intifada in Palestine in 2000 became a powerful inspiration for bin Laden to launch the raids of September 11. As the intifada escalated, bin Laden issued directives to Khalid Sheikh Muhammad and Mohamed Atta to launch the execution of the attacks at an earlier date, on at least two occasions. First occasion was during Ariel Sharon's controversial visit to Al-Haram al-Sharif; which was condemned across the Muslim world and led to the eruption of Al-Aqsa Intifada. Second occasion was when Ariel Sharon visited the White House in March 2001. Throughout this period, Al-Qaeda vehemently denounced Zionist atrocities against Palestinians and denounced the US as being directly complicit in Israeli repression of Palestinians.[30][31]

Arab media coverage of the Second Intifada, which broadcast Israeli atrocities across the world, became a major element of Al-Qaeda's success. Al-Qaeda leaders regularly issued numerous statements declaring the obligation of all Muslims to wage Jihad to liberate Palestine. Bin Laden constantly asserted that America's security will be jeopardized because of its role in undermining the safety of Palestinians.[32][33]

In an interview given to Tayseer Allouni in 21 October 2001, bin Laden stated:

"Jihad is a duty to liberate Al-Aqsa, and to help the powerless in Palestine, Iraq and Lebanon and in every Muslim country. There is no doubt that the liberation of the Arabian Peninsula from infidels is a duty as well. ...Last year’s blessed intifada helped us to push more for the Palestinian issue. This push helps the other cause. Attacking America helps the cause of Palestine and vice versa... All of a sudden, Bush and Blair declared, “The time has come to establish an independent state for Palestine.” Throughout the past years the time hasn’t come, until after these attacks, for the establishment of the Palestinian state. They only understand the language of attacks and killings."[34]

Sanctions against Iraq

[edit]
See also: Sanctions against Iraq

On 6 August 1990, four days after the Iraqi invasion of Kuwait, the United Nations Security Council (UNSC) adopted Resolution 661, which imposed economic sanctions on Iraq, providing for a trade embargo, excluding medical supplies

English Wikisource has original text related to this article:

and "in humanitarian circumstances" foodstuffs, the import of which was tightly regulated. After the end of the Gulf War and after the Iraqi withdrawal from Kuwait, the sanctions were linked to removal of weapons of mass destruction by Resolution 687.[35]

In the 1998 fatwa, al-Qaeda identified the Iraq sanctions as a reason to kill Americans:

despite the great devastation inflicted on the Iraqi people by the crusader-Zionist alliance, and despite the huge number of those killed, which has exceeded 1 million ... despite all this, the Americans are once again trying to repeat the horrific massacres, as though they are not content with the protracted blockade imposed after the ferocious war or the fragmentation and devastation. ... On that basis, and in compliance with Allah's order, we issue the following fatwa to all Muslims: The ruling to kill the Americans and their allies—civilians and military—is an individual duty for every Muslim ...[36][37]

In the 2004 Osama bin Laden video, bin Laden calls the sanctions "the greatest mass slaughter of children mankind has ever known".[38]

Presence of U.S. troops in Saudi Arabia

[edit]
See also: Operation Southern Watch

Following the end of the Gulf War, the U.S. maintained a presence of 5,000 troops stationed in Saudi Arabia.[39] One of the responsibilities of that force was Operation Southern Watch, which enforced the no-fly zones over southern Iraq set up after 1991, and the country's oil exports through the shipping lanes of the Persian Gulf are protected by the US Fifth Fleet, based in Bahrain.

Since Saudi Arabia houses the holiest sites in Islam (Mecca and Medina), many Muslims were upset at the permanent military presence. Bin Laden was furious.[40][41] Before the Gulf War commenced, bin Laden tried to persuade Saudi defense minister Prince Sultan that Saudi Arabia can defend itself with the help of Afghan Arabs, but his ideas were not seriously entertained.[42] In 1992, after bin Laden failed to convince Saudi interior minister Prince Nayef to remove the American presence, he called the Prince a traitor to Islam, prompting King Fahd to declare him persona non grata.[43] Bin Laden then called for Muslims to overthrow the Saudi government, foreshadowing several terrorist attacks in Saudi Arabia in the years to come.[44] The continued presence of US troops after the Gulf War in Saudi Arabia was one of the stated motivations behind the September 11th attacks[39] and the Khobar Towers bombing. Further, the date chosen for the 1998 United States embassy bombings (August 7) was eight years to the day that American troops were sent to Saudi Arabia.[45] Bin Laden interpreted narrations attributed to Muhammad as banning the "permanent presence of infidels in Arabia".[46]

In 1996, by then based in Afghanistan, bin Laden issued a fatwa declaring war on the United States and calling for American troops to get out of Saudi Arabia.[47][48] In the 1998 fatwa, Al-Qaeda wrote: "for over seven years the United States has been occupying the lands of Islam in the holiest of places, the Arabian Peninsula, plundering its riches, dictating to its rulers, humiliating its people, terrorizing its neighbors, and turning its bases in the Peninsula into a spearhead through which to fight the neighboring Muslim peoples."[36] In the December 1999 interview with Rahimullah Yusufzai, bin Laden said he felt that Americans were "too near to Mecca" and considered this a provocation to the entire Muslim world.[49]

Environmental destruction

[edit]
See also: Environmental policy of the United States

In Letter to the American People, bin Laden criticized the United States for having some of the highest rates of greenhouse gas emissions in the world, as well as its failure to ratify the Kyoto Protocol:

You have destroyed nature with your industrial waste and gases more than any other nation in history. Despite this, you refuse to sign the Kyoto agreement so that you can secure the profit of your greedy companies and industries.[50]

Ayman al-Zawahiri, said global warming reflected

how brutal and greedy the Western Crusader world is, with America at its top [51]

Bin Laden has also called for the destruction of the American economy as a way of fighting global warming.[52]

American immorality

[edit]

In the above-mentioned letter, bin Laden lamented the "immoral" behavior that had become the norm in the United States as a motivating factor in his decision to launch the attacks:

The second thing we call you to, is to stop your oppression, lies, immorality and debauchery that has spread among you. (a) We call you to be a people of manners, principles, honour, and purity; to reject the immoral acts of fornication, homosexuality, intoxicants, gambling, and trading with interest.[24][53]

Conflict in Somalia, Chechnya, Kashmir, Lebanon and the Philippines

[edit]

Clause 1B, 4 and 5 of Osama bin Laden's manifesto state that:

"You attacked us in Somalia; you supported the Russian atrocities against us in Chechnya, the Indian oppression against us in Kashmir, and the Jewish aggression against us in Lebanon. ... We also advise you to stop supporting Israel, and to end your support of the Indians in Kashmir, the Russians against the Chechens and to also cease supporting the Manila Government against the Muslims in Southern Philippines. ... We also advise you to pack your luggage and get out of our lands. We desire for your goodness, guidance, and righteousness, so do not force us to send you back as cargo in coffins."[54][55]

Liberation of Muslim lands

[edit]

America's hegemonic influence in the international political system was vehemently denounced by Al-Qaeda. Al-Qaeda leadership asserted that America became a legitimate target to be attacked due to the hostile policies of US governments; such as American support to Zionism, military aggression against countries across the Muslim World, sponsoring of oppressive regimes, American cultural imperialism, etc. Al-Qaeda sought cooperation with those countries that abstained from involvement in Muslim affairs and had no involvement in American imperialism.[56]

In a speech released in 2004, Osama Bin Laden stated:

"free men do not forfeit their security, contrary to Bush’s claim that we hate freedom.

If so, then let him explain to us why we don’t strike for example – Sweden? And we know that freedom-haters don’t possess defiant spirits like those of the 19 – may Allah have mercy on them.

No, we fight because we are free men who don’t sleep under oppression. We want to restore freedom to our nation, just as you lay waste to our nation. So shall we lay waste to yours.

No one except a dumb thief plays with the security of others and then makes himself believe he will be secure. Whereas thinking people, when disaster strikes, make it their priority to look for its causes, in order to prevent it happening again."[57]

Inferred motives

[edit]

Political analysts have inferred some motives for the attacks that were not explicitly stated by Al-Qaeda, such as globalization and a desire to provoke the United States.

Elliot Neaman stated that the connections Walt and Mearsheimer and others, including many German intellectuals, make between 9/11 and Israel are ahistorical.[58] He argues that the Palestinians themselves have often pointed to their betrayal by one Arab leader after another since the founding of the state of Israel, and further that bin Laden is no exception, as he never showed any concern for the Palestinian cause until he came under the influence of Ayman Al-Zawahiri and decided to use the Palestinians as a means to gain the favor of militant Muslims. Al-Qaeda and Hamas continue to have a fraught relationship, and have been argued to have different goals in regard to the Israeli–Palestinian conflict.[59]

Religious motivation

[edit]

Daniel Benjamin and Steven Simon, in their book, The Age of Sacred Terror, argue that the 9/11 terrorist attacks are purely religious. They are seen as "a sacrament ... intended to restore to the universe a moral order that had been corrupted by the enemies of Islam." It is neither political nor strategic but an "act of redemption" meant to "humiliate and slaughter those who defied the hegemony of God."[60]

Raymond Ibrahim, as a researcher at the Library of Congress, found a significant difference between Al Qaeda's messages in English directed to a Western audience and al Qaeda's Arab messages and documents directed to an Islamic audience. The Western-directed messages listed grievances as grounds for retaliation employing the "language of 'reciprocity.'" Literature for Islamic audiences contained theological motivations bereft of references to the acts of Western nations.[61][62]

Globalization

[edit]

Bernard Lewis is the best-known exponent of the idea of the "humiliation" of the Islamic world through globalization. In the 2004 book The Crisis of Islam: Holy War and Unholy Terror, he argues animosity toward the West is best understood with the decline of the once powerful Ottoman Empire, compounded by the import of western ideas, as seen in Arab socialism, Arab liberalism and Arab secularism.

During the past three centuries, the Islamic world has lost its dominance and its leadership, and has fallen behind both the modern West and the rapidly modernizing Orient. This widening gap poses increasingly acute problems, both practical and emotional, for which the rulers, thinkers, and rebels of Islam have not yet found effective answers.[63]

In an essay titled "The spirit of terrorism",[64] Jean Baudrillard described 9/11 as the first global event that "questions the very process of globalization".[64]

Provocation of war with the United States

[edit]
See also: Pan-Islamism and Secularism in the Middle East

Some Middle East scholars—such as Michael Scott Doran and Peter Bergen—have argued that 9/11 was a strategic way to provoke America into a war that incites a pan-Islamist revolution. Doran argued that the attacks are best understood as being part of a religious conflict within the Muslim world. In an essay, Doran argued that bin Laden's followers "consider themselves an island of true believers surrounded by a sea of iniquity".[65] Doran further argued that bin Laden hoped that US retaliation would unite the faithful against the West, sparking revolutions in Arab nations and elsewhere, and that the Osama bin Laden videos were attempting to provoke a visceral reaction in the Middle East aimed at a violent reaction by Muslim citizens to increased US involvement in their region.[66]

Bergen argued that the attacks were part of a plan to cause the United States to increase its military and cultural presence in the Middle East, thereby forcing Muslims to confront the idea of a non-Muslim government and establish conservative Islamic governments in the region.[67]

U.S. President George W. Bush did in fact declare a War on Terror, which resulted in the temporary loss of control of Afghanistan by the Al-Qaeda-allied Taliban after fighting for two decades. Despite criticism that the Iraqi government had no involvement with the September 11 attacks, Bush declared the 2003 invasion of Iraq to be part of the War on Terror. The resulting backlash and instability enabled the rise of Islamic State and the temporary creation of an Islamic caliphate holding territory in Iraq and Syria, until IS lost its territory through military defeats.

Research on suicide terrorism

[edit]

Robert Pape identified 315 incidents, all but 14 of which they classified as part of 18 different campaigns. These 18 shared two elements and all but one shared a third:[68] 1) A foreign occupation; 2) by a democracy; 3) of a different religion. Mia Bloom interviewed relatives and acquaintances of suicide terrorists. Her conclusions largely support Pape's, suggesting that it is much more difficult to get people to volunteer for a suicide mission without foreign occupation.[69]

Motives for the September 11 attacks

View on Grokipedia
from Grokipedia
The motives for the , carried out by militants under Osama bin Laden's direction, centered on grievances against U.S. in Muslim-majority regions, including the presence of American troops on the , financial and military support for in its conflict with , and on that bin Laden alleged caused the deaths of over one million Iraqi children. These attacks, involving the hijacking of four U.S. commercial airliners to target economic, military, and political symbols, were framed by as obligatory to compel the withdrawal of U.S. forces from holy Islamic lands and to halt perceived aggressions against . Bin Laden articulated these rationales in primary declarations, beginning with his 1996 fatwa demanding the expulsion of U.S. forces from —home to Islam's holiest sites—due to their stationing there since the 1991 , which he deemed a desecration enabling ongoing subjugation of Muslims. The 1998 fatwa escalated this to a binding religious call for killing Americans and their allies worldwide, citing as further justifications U.S.-backed Israeli occupation of Palestinian territories and the starvation effects of sanctions enforced against , which bin Laden portrayed as deliberate mass murder of Muslim civilians. In his 2002 "Letter to America," bin Laden reiterated these points while adding accusations of U.S. exploitation of Muslim resources, propping up secular dictators in Arab states, and broader cultural impositions, rejecting claims that the conflict stemmed from hatred of democratic freedoms by questioning why non-interventionist nations like were spared. Al-Qaeda's strategic aim extended beyond immediate retaliation to provoking a broader clash that would drain U.S. resources through prolonged wars in Muslim countries, thereby weakening American power and inspiring global jihadist recruitment, as evidenced by bin Laden's post-attack statements emphasizing economic disruption and the defense of Islamic . Controversies persist over interpretive biases in secondary analyses, with some Western accounts emphasizing abstract ideological hatred over these policy-specific triggers, despite bin Laden's explicit disavowal of such framings in favor of causal grievances tied to geopolitical actions. Primary documents from leaders reveal a consistent focus on causal retaliation rather than unprovoked enmity, underscoring the role of perceived humiliations in fueling the organization's operational decisions.

Al-Qaeda's Ideological Foundations

Salafi-Jihadist Doctrine and Global Caliphate Goals

Salafi-jihadism, the core ideology of , integrates the puritanical Salafi interpretation of —which emphasizes emulating the practices of the (the first three generations of Muslims)—with a jihadist imperative to wage offensive holy war against perceived enemies of . This doctrine rejects modern nation-states, secular governance, and innovations () as deviations from pure monotheism (), labeling Muslim rulers who ally with non-Muslims as apostates (murtaddun) deserving of overthrow. 's foundational texts and leaders, including , framed not merely as defensive but as a collective obligation (fard al-kifaya elevated to fard al-ayn) to purify the faith and expand Islamic dominion globally. Central to this worldview is the pursuit of a global , envisioned as a supranational Islamic uniting (global Muslim community) under a single caliph enforcing law without compromise. ideologues, drawing from thinkers like and Abdullah Azzam, posited that the caliphate's restoration requires sequential jihad: first against "near enemies" (apostate Muslim regimes), then "far enemies" (Western powers, particularly the , seen as propping up these regimes and crusading against ). Bin Laden adapted this into a strategy, where elite would spearhead a decentralized global to weaken superpowers, incite Muslim masses, and create power vacuums for caliphal governance. The September 11 attacks aligned with this doctrine by targeting symbols of American economic, military, and political power, aiming to provoke overreaction that would expose U.S. vulnerabilities, rally the ummah against "crusaders and Zionists," and accelerate the collapse of apostate governments in Muslim lands—prerequisites for caliphal unification. Salafi-jihadists viewed such spectacular violence as redemptive, promising martyrdom (shahada) and divine victory to reverse centuries of perceived humiliation since the Ottoman caliphate's fall in 1924. This eschatological framing elevated jihad as Islam's paramount virtue, subordinating all else to territorial and ideological conquest.

Evolution of Osama bin Laden's Worldview

, born on March 10, 1957, in , , into a prominent construction magnate family, initially absorbed Wahhabi-influenced piety from his upbringing and education, but his ideological accelerated in the late 1970s through exposure to Islamist preachers advocating resistance to secular and communist threats. During his studies at in , he encountered ideas via figures like , brother of the executed theorist , emphasizing (declaring Muslims apostates) and against perceived internal enemies of Islam. This period laid groundwork for viewing governance in Muslim lands as illegitimate if it deviated from strict , though bin Laden's early focus remained more pragmatic than revolutionary. The Soviet invasion of Afghanistan in December 1979 catalyzed bin Laden's shift toward active , prompting him to travel to , , in 1980 to support fighters with funding and logistics drawn from his family's wealth. Collaborating with Palestinian scholar Abdullah Azzam, he co-founded the al-Afghaniya (Afghan Services Bureau) in 1984 to recruit, train, and supply Arab volunteers, framing the conflict as a defensive to expel occupiers from Muslim territory—a classical Islamic imperative endorsed by mainstream scholars at the time. Bin Laden occasionally participated in combat but primarily excelled in organizational and financial roles, amassing a network of fighters whose victory over the Soviets by 1989 reinforced his belief in asymmetric warfare's efficacy against superpowers. Following the Soviet withdrawal and Azzam's assassination in November 1989—possibly by rivals favoring broader —bin Laden formalized in August 1988 as a to sustain global unity beyond , initially envisioning it as a base for future defensive struggles rather than immediate offensive campaigns. The 1990-1991 marked a pivotal rupture: bin Laden proposed deploying 100,000 Arab veterans to defend against , but the Saudi monarchy opted for U.S. troops, which he decried as an occupation of Islam's holiest lands by "Crusaders and ." This rejection fueled his disillusionment with apostate regimes, evolving his worldview from localized defense to offensive global targeting the "far enemy"—the —as the root enabler of Muslim subjugation through military presence, alliances with , and sanctions. Exiled to in 1991 and later in 1996, he escalated this ideology, prioritizing strikes on American assets to provoke withdrawal and inspire mass uprising, diverging from Azzam's restraint against civilians and non-combatants.

Primary Sources and Explicit Statements

1996 Declaration of War Against the United States

On August 23, 1996, released the " Against the Americans Occupying the Land of the Two Holy Places," a manifesto published in the London-based Arabic newspaper . Issued from his base in after his expulsion from earlier that year, the 12-page Arabic text explicitly called for to expel U.S. forces from the , framing their presence as a religious violation of Islam's sacred territories— and in . Bin Laden positioned this as a defensive obligation under Islamic law, invoking historical precedents like the Muhammad's expulsion of polytheists from the Hijaz region. The declaration's core grievance centered on the stationing of approximately 5,000–10,000 U.S. troops in since Operation Desert Shield in 1990, which bin Laden described as an "occupation" enabling the plundering of Muslim resources and subjugation by the Saudi monarchy, which he accused of for permitting it. He cited specific incidents, such as U.S. airstrikes on during the and ongoing sanctions, as evidence of broader American aggression against Muslims, though the primary focus remained the "infidel" military bases near holy sites. Bin Laden rejected diplomatic resolutions, arguing that the U.S.-Saudi alliance had corrupted Islamic governance and that only armed resistance could restore sovereignty. Bin Laden outlined tactical prescriptions for jihad, urging Muslims to target U.S. military personnel and assets through , , and assassinations, while extending the call to civilians complicit in the occupation. He drew on Salafi interpretations of texts like Ibn Taymiyyah's rulings against Mongol invaders to justify killing as a religious , emphasizing collective participation from (global Muslim community). Secondary references included U.S. support for in the Palestinian territories, portrayed as part of a Crusader-Zionist , but these were subordinated to the Saudi occupation theme. This document marked bin Laden's first public escalation from regional Afghan jihad to global confrontation with the , mobilizing al-Qaeda's network and foreshadowing attacks like the 1998 embassy bombings. It rejected U.S. claims of defensive troop deployments post-Gulf War, instead interpreting them through a lens of perpetual religious conflict, with no acknowledgment of mutual security arrangements between the U.S. and Saudi governments.

1998 Fatwa on Jihad Against Jews and Crusaders

The 1998 , formally known as the "World Islamic Front Statement Urging Against Jews and Crusaders," was publicly issued on February 23, 1998, and signed by as the primary author, alongside (leader of ), Abu Yasir Rifa'i Ahmad Taha (leader of the Egyptian Islamic Group), Mir Hamzah (secretary of Jamiat ul-Ulema-e-Pakistan), and Fazlur Rahman (representing Jamiat ul-Ulema-e-Hind from ). Published in the London-based Arabic newspaper , the document framed against the and as a religious , building on bin Laden's 1996 declaration of war by broadening the targets to include all Americans—civilian and military—and their allies worldwide. It positioned these acts as defensive responses to perceived aggressions against , citing Quranic verses and prophetic traditions to argue that must expel infidels from Muslim lands or face divine punishment. The enumerated three principal grievances against the . First, it accused the U.S. of occupying the —Islam's holiest region, including and —for over seven years following the 1990-1991 , claiming American forces plundered Saudi resources, dictated to its rulers, humiliated its people, and used bases to attack neighboring Muslim states like . Second, it alleged U.S. complicity in Israeli control over , including the plundering of the , by replacing Muslim with Jewish forces and supporting the displacement of . Third, it condemned U.S. alliances with "apostate" regimes in Muslim countries (such as , , and ) that suppressed Islamic movements, and highlighted economic sanctions on —imposed after its 1990 invasion of —as causing the deaths of over one million Iraqi children through and . Religiously, the statement invoked Surah Al-Tawbah (9:5) from the , interpreting it as a command to fight polytheists until they convert or pay tribute, and referenced hadiths attributing to the Prophet Muhammad a of killing in the end times. It rejected partial truces or negotiations, asserting that ongoing U.S. presence in Muslim lands invalidated any peace and required immediate action. The core ruling declared: "The ruling to fight the Americans and their allies, civilians and military, is an individual obligation for every Muslim who can do it in any country in which it is possible to do it, in order to liberate the and the holy mosque of ." This served as a foundational ideological document for , explicitly linking these motives to a global that justified indiscriminate violence against Western targets, including the , 2001, attacks, which bin Laden later cited as fulfillment of this obligation. Unlike bin Laden's earlier statements focused primarily on , the 1998 declaration universalized the conflict, portraying the U.S. as the head of a "Crusader-Zionist" alliance intent on destroying , thereby mobilizing a broader network of jihadists.

Post-9/11 Letters and Videos by Al-Qaeda Leaders

In a video statement aired by Al Jazeera on October 7, 2001, coinciding with the start of U.S. military operations in , praised the as a divine response to perceived U.S. aggressions against , citing American support for in the Palestinian territories, military presence on the , sanctions on , and interventions in and as provocations that justified retaliation. He framed the strikes as part of a broader defensive against the "crusader-Zionist alliance," echoing themes from his pre-9/11 declarations while emphasizing that the timing aligned with U.S. actions in . A subsequent videotape, recovered by U.S. forces in and released by the U.S. Department of Defense on December 13, 2001, featured bin Laden explicitly claiming responsibility for the attacks and detailing , including the selection of targets to maximize economic and symbolic damage to the U.S. In the recording, dated November 2001, bin Laden reiterated motives rooted in opposition to U.S. , stating that the hijackers acted to avenge Muslim suffering caused by American "injustices" such as the stationing of troops near holy sites in and backing of Israeli actions, which he described as fulfilling religious obligations under Islamic law to combat occupation and aggression. Bin Laden's "," disseminated online in November 2002 via al-Qaeda-linked websites, provided the most detailed post-9/11 articulation of motives, attributing the attacks to U.S. support for —including financial and military aid enabling operations in —and the occupation of Muslim lands, particularly the presence of U.S. forces in since the 1991 . The document accused the U.S. of killing over 34,000 Palestinian children through proxy actions and imposing sanctions on that resulted in the deaths of more than 1.5 million civilians, primarily children, framing these as deliberate policies warranting ; it also condemned U.S. interventions in , , , and as part of a pattern of crusader aggression against . Bin Laden positioned the attacks as a call for Americans to convert to or face continued conflict, arguing that ending alliances with and withdrawing from Muslim territories would avert further violence. Ayman al-Zawahiri, al-Qaeda's deputy leader, reinforced these themes in post-9/11 videos, such as a September 2003 message where he described the attacks as retaliation for U.S. "crimes" against , including the desecration of Islamic holy sites and support for secular regimes in the , urging continued to expel Western influence from dar al-Islam. These statements aligned closely with bin Laden's, portraying 9/11 as a strategic blow to compel U.S. policy changes rather than mere vengeance, though al-Zawahiri emphasized ideological purification and the establishment of governance as ultimate goals intertwined with the grievances cited.

The initiated a significant to on August 7, 1990, in response to Iraq's invasion of on August 2, 1990, at the explicit invitation of the Saudi government to deter further Iraqi aggression. This buildup, known as Operation Shield, involved over 500,000 U.S. troops by early 1991, marking one of the largest rapid deployments in U.S. military history. Following the successful coalition expulsion of Iraqi forces from in February 1991, troop levels were substantially reduced, but a permanent rotational presence persisted to support ongoing containment of Saddam Hussein's regime, including enforcement of United Nations-authorized no-fly zones over southern . Operation Southern Watch, launched in August 1992, formalized this role, with U.S. forces operating from Saudi bases such as near . Approximately 5,000 to 6,000 U.S. personnel, predominantly Air Force airmen, were stationed there at any given time through 2003, supported by around 120 aircraft conducting patrols and strikes against Iraqi violations. This presence was maintained under bilateral agreements with , focused on regional stability rather than direct territorial control, though it involved access to airfields and logistical upgraded specifically for U.S. operations. Osama bin Laden, having returned from combat against Soviet forces in , viewed the U.S. deployment as a profound betrayal by the Saudi monarchy and a of the , which encompasses Islam's holiest sites, and . In 1990, bin Laden offered to mobilize thousands of Arab veterans to defend the kingdom against , but Saudi leaders rejected the proposal in favor of American assistance, prompting his growing opposition and eventual exile to in 1991, followed by the revocation of his Saudi citizenship in 1994. Bin Laden articulated this grievance as a central casus belli in his August 23, 1996, "Declaration of Jihad Against the Americans Occupying the Land of the Two Holiest Sites," where he described U.S. forces as "Crusaders" who had "occupied the land of the two holy places" since the Gulf War, violating Quranic injunctions against polytheist armies on the Peninsula. He framed their presence as the "greatest disaster" befalling Muslims, enabling alleged corruption of Islamic governance and serving as a rallying cry for global jihad to expel them. Al-Qaeda leaders, including bin Laden, reiterated this in the February 23, 1998, fatwa co-signed with allied clerics, condemning the "occupation of the Arabian Peninsula, which is the land of the two holy places" as part of a broader U.S. assault on Islam, justifying attacks on American civilians and military personnel worldwide. This objection resonated within al-Qaeda's Salafi-jihadist ideology, which interprets Islamic texts to prohibit non-Muslim military garrisons in the Hijaz region, equating the U.S. role with historical Crusader incursions despite the Saudi invitation and defensive intent. Bin Laden's statements positioned the presence not merely as a but as enabling moral decay and subservience to infidels, fueling by portraying withdrawal as a prerequisite for restoring Islamic . The U.S. relocated its combat forces from in 2003 amid shifting regional dynamics, but al-Qaeda continued to invoke the episode in post-9/11 communications as emblematic of unresolved Western interference.

U.S. Support for Israel and the Israeli-Palestinian Conflict

Al-Qaeda's grievances against U.S. support for Israel centered on perceptions of American complicity in Israeli military actions and occupation of Palestinian territories, particularly Jerusalem and the al-Aqsa Mosque, which bin Laden framed as religious desecration requiring defensive jihad. This issue was articulated as one of three core complaints—alongside U.S. troops in Saudi Arabia and sanctions on Iraq—motivating attacks on American targets to compel policy reversal. Bin Laden portrayed U.S. annual military aid to Israel, totaling over $3 billion by the late 1990s, as enabling aggression against Muslims, including demolitions of Palestinian homes and killings of civilians. In the February 23, 1998, fatwa titled "Jihad Against Jews and Crusaders," issued by bin Laden and allies, the U.S. was accused of sustaining Israel's "brutal crusade occupation" through support that fragmented Arab states and ensured the "petty state" of Israel's survival at Muslim expense. The document explicitly mandated killing Americans and allies as "an individual duty for every Muslim" to "liberate the al-Aqsa Mosque and the holy mosque [Mecca] from their grip," directly tying Palestinian sites under Israeli control to the need for global jihad against U.S. interests. This religious ruling elevated the conflict to a pan-Islamic obligation, arguing U.S. backing allowed Israel to occupy Jerusalem and murder Muslims without restraint. During a May 1998 interview with ABC News correspondent John Miller in , bin Laden elaborated on these charges, condemning U.S. policy for defending while labeling Palestinian resistors as terrorists: "Americans accuse our children in of being terrorists—those children, who have no weapons and have not even reached maturity. At the same time, Americans defend a country, the state of the , that has a policy to destroy the future of these children." He cited specific Israeli actions, such as "houses... demolished over the heads of children," as enabled by American influence, urging U.S. citizens to demand a government prioritizing their interests over "the interests of the " to avert retaliation. Bin Laden warned that persistent "tyranny" would extend the conflict to American soil, referencing prior plots like Ramzi Yousef's as precursors. These statements positioned U.S.-Israeli alliance as a catalyst for 's strategy, though operational focus remained on American assets rather than direct Palestinian involvement; pre-9/11, conducted no major attacks tied explicitly to the conflict, using it instead for ideological mobilization and recruitment. Bin Laden's rhetoric invoked historical caliphate-era duties to reclaim , blending Salafi theology with geopolitical critique to justify spectacular violence against the U.S. as a means to pressure withdrawal of support.

Sanctions and Military Actions Against Iraq

Al-Qaeda leaders, including Osama bin Laden, frequently invoked the United Nations sanctions regime against Iraq—imposed via UN Security Council Resolution 661 on August 6, 1990, following Iraq's invasion of Kuwait—as a key justification for jihad against the United States, framing it as deliberate mass murder of Muslim civilians. In his February 23, 1998, fatwa "Jihad Against Jews and Crusaders," bin Laden asserted that the sanctions had resulted in the deaths of more than 600,000 Iraqi children due to shortages of food and medicine, positioning this as evidence of American criminality and aggression against the Islamic world. This claim echoed earlier propaganda disseminated by the Iraqi regime under Saddam Hussein, which attributed civilian hardships primarily to the sanctions rather than internal mismanagement, corruption, or the regime's diversion of resources to military and palace-building programs. The sanctions, maintained through the 1990s despite the introduction of the Oil-for-Food Program in 1995 (UNSC Resolution 986), were estimated by some humanitarian reports to have contributed to excess child mortality rates. A 1999 UNICEF assessment, drawing on Iraqi Ministry of Health data, suggested approximately 500,000 additional child deaths between 1991 and 1998 compared to pre-Gulf War levels, though subsequent analyses, including a 2001 peer-reviewed study in the Journal of Epidemiology and Community Health, attributed much of the crisis to Saddam Hussein's policies, such as the destruction of water treatment infrastructure during the 1991 war and ongoing repression, rather than sanctions alone. Bin Laden and al-Qaeda exploited these figures in recruitment and ideological materials, portraying the U.S. as the primary culprit for a "genocide" against Muslims, thereby fueling anti-American sentiment without acknowledging Iraq's role in initiating the conflict or the UN's multilateral enforcement. Complementing grievances over sanctions, condemned U.S. military interventions in , including the 1991 (Operation Desert Storm, January 17–February 28), which expelled Iraqi forces from and involved coalition airstrikes that destroyed significant Iraqi infrastructure, leading to an estimated 20,000–35,000 Iraqi military deaths and indirect civilian casualties from post-war chaos. Ongoing U.S.-led enforcement of no-fly zones over northern and southern from 1991 onward, justified to protect Kurdish and Shiite populations from Saddam's reprisals, included periodic airstrikes, such as Operation Desert Fox (December 16–19, 1998), which targeted weapons facilities and reportedly killed hundreds of Iraqi personnel. In a May 1998 , bin Laden described these actions as part of a broader American occupation and crusade against , estimating that sanctions and bombings had collectively killed around 1 million Iraqis, a figure that amplified calls for retaliatory strikes on U.S. soil to deter further interventions. These narratives positioned Iraq's plight as emblematic of U.S. imperialism, aligning with al-Qaeda's strategic aim to unite against perceived Western subjugation.

U.S. Interventions in Other Muslim-Majority Regions

U.S. forces participated in Operation Restore Hope in from December 1992 to March 1993, leading a multinational coalition under UN auspices to secure delivery amid and , involving up to 28,000 troops at peak. The mission transitioned to UNOSOM II in May 1993, escalating to armed operations against warlord , culminating in the Battle of Mogadishu on October 3, 1993, where 18 U.S. Rangers and operators were killed, alongside over 1,000 Somali casualties reported by some accounts. , through affiliated networks including members, claimed involvement in supporting Somali fighters against U.S. and UN forces, portraying the intervention as a "Crusader" invasion of Muslim territory aimed at subjugating Somalis under the guise of humanitarianism. Osama bin Laden referenced the Somalia intervention in his August 23, 1996, Declaration of Jihad, listing it among U.S. aggressions against Muslims and highlighting the "defeat of the American forces in Somalia" as evidence of vulnerability exploitable through persistent resistance, framing the initial deployment as part of a pattern of infidel occupation of Islamic lands. This narrative positioned U.S. actions in Somalia not as neutral peacekeeping but as ideological warfare echoing historical , motivating recruitment by demonstrating that asymmetric could compel superpower withdrawal after inflicting casualties. In August 1998, following al-Qaeda's bombings of U.S. embassies in and , the U.S. launched , firing 13 Tomahawk missiles at the Al-Shifa pharmaceutical plant in , , on August 20, destroying the facility—Sudan's primary source of medicine—and killing at least one Sudanese employee, with estimates of broader health impacts from lost drug production. U.S. intelligence alleged the site produced chemical weapons precursors linked to bin Laden, a claim disputed by Sudanese authorities and independent analyses questioning evidence of nerve gas production. Bin Laden and interpreted the strike as unprovoked aggression against a sovereign Muslim nation harboring him previously (1991–1996), exemplifying U.S. willingness to bomb civilian infrastructure in Islamic countries under pretexts of , thereby justifying retaliatory . Al-Qaeda's 1998 fatwa further articulated grievances against U.S. designs to "fragment" Muslim states like into weak entities subservient to Western interests, viewing such interventions as strategic encirclement to bolster and suppress Islamic unity. Similarly, U.S. naval presence in , including port visits and advisory support against Islamist groups, fueled perceptions of creeping military footholds in the Arabian Peninsula's periphery, as evidenced by al-Qaeda's October 2000 attack on the USS Cole in harbor, which killed 17 U.S. sailors and was framed as defensive response to American "occupation" of Muslim waters. These episodes reinforced bin Laden's worldview of U.S. interventions as a coordinated assault on Muslim sovereignty, distinct from core complaints about , , and , yet integral to the imperative for global retaliation.

Cultural and Moral Objections Raised

Perceived American Immorality and Secularism

Al-Qaeda's ideological framework portrayed American society as emblematic of moral decay, characterized by the endorsement of vices such as alcohol consumption, gambling, usury, and homosexuality, which bin Laden explicitly condemned as spreading debauchery among Muslim youth through exported media and cultural influence. In his 2002 "Letter to America," Osama bin Laden accused the United States of permitting "acts of immorality" and fostering a culture where such behaviors were normalized, positioning this as a direct affront to Islamic principles of modesty and piety. He further criticized the American separation of religion from public policy and governance, equating the invocation of God in political discourse with "backwardness" and "terrorism," thereby framing secularism as an aggressive promotion of atheism that undermined the sovereignty of Sharia law in Muslim societies. This perception extended to al-Qaeda's view of U.S. cultural exports, including Hollywood films, , and entertainment industries, as vehicles for disseminating vice and eroding traditional Islamic family structures and gender roles. Bin Laden argued that ordinary Americans bore collective responsibility for these societal norms by electing leaders who upheld them and funding policies that propagated secular values abroad, such as through military bases in that symbolized the intrusion of godless influences into holy lands. , al-Qaeda's deputy, echoed this by denouncing Western-style democracy as a "new religion" antithetical to , reinforcing the narrative that American secular governance posed an ideological threat comparable to physical occupation. These cultural and moral objections were not isolated but intertwined with al-Qaeda's salafist-jihadist doctrine, which held that confronting the "far enemy"—America—was essential to purify from corrupting external forces before addressing internal . Bin Laden's statements positioned the attacks on , 2001, as a defensive against a he deemed the "worst" in for its vices, though primary fatwas like the 1998 declaration emphasized geopolitical grievances more prominently, with moral critiques serving to justify targeting civilians as complicit enablers. Empirical analyses of captured al-Qaeda documents confirm this ideological consistency, revealing training materials that vilified Western as a form of (pre-Islamic ignorance) warranting violent opposition.

Accusations of Cultural and Environmental Imperialism

leaders, particularly , accused the of cultural imperialism by disseminating , moral permissiveness, and Western values that allegedly corroded Islamic societies and traditional norms. In his October 2002 "," bin Laden condemned American freedoms as enabling , , alcohol, , and —practices he described as violations of divine law and hallmarks of a corrupt imposed on through media and alliances with apostate regimes. He specifically targeted U.S. cultural exports like Hollywood films as tools for ideological subversion, claiming they glorified vice while supporting policies that desecrated holy sites and prioritized Jewish interests over Muslim sovereignty. These accusations framed U.S. influence as an extension of colonial domination, where military presence in after the 1990–1991 facilitated the influx of non-Islamic customs, including mixed-gender interactions and consumerist lifestyles antithetical to . Bin Laden's 1996 against the U.S. portrayed the Saudi monarchy's hospitality toward American forces as enabling this cultural erosion, arguing it betrayed by allowing infidel troops to corrupt the Arabian Peninsula's sanctity. Such positioned as a defensive response to preserve Islamic purity against perceived American efforts to secularize and morally degrade Muslim populations. Environmental imperialism entered al-Qaeda's grievances through claims of resource plunder and ecological harm tied to U.S. interventions in Muslim-majority regions. Bin Laden alleged that America exhausted Islamic lands' wealth, especially and , by propping up exploitative regimes and enforcing policies like post-1991 sanctions that starved civilians while securing energy flows for Western consumption. In the 1996 declaration, he decried U.S. occupation of holy territories as safeguarding oil extraction at the expense of Muslim , implying broader despoliation of natural endowments. Though less emphasized than or cultural critiques, these charges portrayed U.S. basing and operations—such as in —as contributors to localized degradation, framing resource dominance as a form of imperial sustenance that justified retaliatory strikes.

Strategic and Tactical Inferences from Al-Qaeda Actions

Intent to Provoke Overreaction and Resource Drain

Al-Qaeda's strategic calculus for the included a deliberate aim to elicit an exaggerated and economic response from the , thereby imposing unsustainable costs and weakening its global position through attrition. , in a videotaped message released on October 29, 2004, explicitly outlined this objective, stating that sought to "bleed America to the point of bankruptcy" by continuing a policy of asymmetric confrontation that mirrored their earlier success in draining Soviet resources during the Afghan jihad of the 1980s. He claimed the attacks themselves cost al-Qaeda roughly $500,000 while inflicting damages exceeding $500 billion on the U.S. economy, framing the operation as a high-return in protracted conflict designed to exploit America's reliance on expensive . This intent aligned with bin Laden's broader vision of provoking U.S. overextension into Muslim-majority territories, anticipating invasions that would not only strain American finances but also radicalize additional recruits by portraying the response as imperial aggression. In the same 2004 address, bin Laden referenced baiting the Bush administration into opening multiple "war fronts" for the benefit of corporate interests like , calculating that such reactions would amplify al-Qaeda's narrative of defending against occupation. The destruction of the World Trade Center towers was cited as a calculated provocation to "get them out of their land" while forcing resource-intensive countermeasures, including the subsequent U.S.-led in October 2001 and in March 2003, which al-Qaeda viewed as fulfilling their trap. Empirical outcomes partially validated this strategy from al-Qaeda's perspective, as U.S. post-9/11 military engagements incurred expenditures totaling trillions of dollars over two decades, though bin Laden's attribution of direct causality overstated al-Qaeda's isolated influence amid broader geopolitical decisions. Intercepted communications and al-Qaeda training manuals from the era reinforced this emphasis on economic disruption over symmetric battles, prioritizing spectacles that compelled opponents to overcommit resources in retaliation.

Expansion of Jihad and Recruitment Through Spectacle

Al-Qaeda's planning for the emphasized targets that would maximize visual impact and media coverage, such as the World Trade Center and , to create a spectacle symbolizing strikes against American power. This approach aligned with the group's broader doctrine of using dramatic operations to propagate ist ideology, as articulated by leaders like , who viewed such acts as essential for elevating al-Qaeda's profile beyond regional conflicts. , the operation's principal architect, proposed the hijackings to bin Laden in 1996 precisely for their potential to deliver a "spectacular" blow, aiming to rally support by showcasing operational success against a . The attacks' televised destruction—resulting in the collapse of the Twin Towers before millions—was calculated to demoralize the while invigorating the global Muslim community () to perceive as a viable for resistance. Bin Laden and associates anticipated that the imagery of humiliated American icons would serve as , encouraging recruitment by framing the strikes as divine validation of against the "far enemy." Captured documents and interrogations of figures like Mohammed confirm this intent: the operation sought to "awaken consciences" and inspire Muslims to join the fight, expanding from localized insurgencies to a transnational movement. Post-attack statements reinforced this motive; in an October 2001 video, bin Laden described the events as initiating an "awakening" among , with recruits reportedly flocking to camps in response to the perceived triumph. Annual commemorations by , labeling 9/11 the "Manhattan Raid," continued to invoke the attacks' spectacle to sustain recruitment appeals, claiming they provoked U.S. overreach while boosting ideological adherence worldwide. This strategy contributed to the proliferation of affiliates in regions like , , and in the years following, as the operation's notoriety drew ideological sympathizers seeking to emulate its scale. However, while short-term inspirational effects were evident in heightened jihadist activity, systemic biases in Western analyses of such recruitment—often downplaying ideological drivers in favor of grievance narratives—have led to debates over the attacks' net expansionary impact.

Alignment with Patterns in Prior Al-Qaeda Operations

The exemplified 's recurrent strategy of employing suicide operatives in coordinated assaults on high-profile U.S. symbols of power, building directly on tactics refined in prior operations such as the 1998 bombings of U.S. embassies in , , and , , which killed 224 people using simultaneous truck bombs timed for maximum disruption during business hours. These embassy strikes, orchestrated by figures like and , targeted diplomatic outposts representing American influence in Muslim-majority regions, mirroring 9/11's selection of the World Trade Center as an economic icon and as a hub to undermine U.S. global projection. Similarly, the October 12, 2000, suicide bombing of the USS Cole in Harbor, , which claimed 17 American sailors using a small boat laden with explosives, demonstrated Al-Qaeda's pattern of naval interdiction against U.S. forces deployed near Islamic holy sites, aligning with 9/11's aim to strike naval-adjacent infrastructure while escalating to domestic territory. Al-Qaeda's modus operandi consistently involved small teams of trained jihadists from Afghan camps, utilizing forged documents and commercial conveyance for infiltration, as seen in the 1993 World Trade Center truck bombing—perpetrated by with indirect ties to emerging networks—which sought to topple the towers and kill tens of thousands, prefiguring 9/11's aviation-based demolition of the same structures. This operation's focus on economic disruption through symbolic destruction recurred in 9/11, where 19 hijackers, many with prior combat experience, executed a low-cost ($400,000–$500,000) plot involving and box cutters, evolving from earlier explosive methods to hijacked as improvised missiles. The 1994–1995 , led by (later 9/11's architect), tested mid-air bombings on flights and envisioned crashing planes into U.S. targets like CIA headquarters, directly prototyping 9/11's airborne suicide paradigm while adhering to 's objective of bleeding U.S. resources through spectacular violence. Objectives across these pre-9/11 actions—expelling U.S. forces from the , retaliating for perceived interventions, and inspiring global recruitment—remained invariant, as articulated in bin Laden's 1996 fatwa and 1998 , which framed attacks on civilians as justifiable under jihadist doctrine. The 1995 and 1996 Khobar Towers bombings in , killing American personnel at military facilities, reinforced this anti-occupation thrust, with providing ideological and logistical inspiration despite varying direct involvement. 9/11 represented not a departure but an amplification: shifting from overseas peripheral strikes to the U.S. homeland for psychological magnification, yet preserving the pattern of minimal footprints, martyr operations, and fatwa-driven rationales to provoke overreaction and sustain the "far enemy" campaign against America. This continuity underscores 's adaptive persistence, with 9/11's four-plane synchronization echoing the embassy bombings' simultaneity but scaled for unprecedented media resonance.

Debates on Motive Interpretations

Supremacist Ideology vs. Policy Grievance Frameworks

The supremacist ideology framework posits that al-Qaeda's actions, including the , were fundamentally driven by a Salafi-jihadist seeking to reestablish a global under strict law, viewing the as the primary obstacle due to its perceived role in propping up "apostate" Muslim regimes and promoting secular values antithetical to . This ideology, influenced by thinkers like and Ibn Taymiyyah, frames the conflict as a cosmic struggle between believers and infidels (" and Crusaders"), where violent is a religious to expel non-Muslims from Islamic lands and ultimately subjugate or eliminate Western influence worldwide. Al-Qaeda's own documents and training materials emphasize martyrdom, the rejection of and pluralism, and the pursuit of weapons of mass destruction as a divine imperative, indicating motives transcending temporal disputes. In contrast, the policy grievance framework interprets the attacks primarily as retaliatory responses to specific U.S. decisions, such as the stationing of s in after the 1990-1991 , unconditional support for , and economic sanctions on that reportedly caused over 500,000 child deaths according to some estimates cited by . Bin Laden's 1998 explicitly lists these as , portraying U.S. presence on the as a of holy sites and against , framing as a defensive duty to liberate occupied lands. Proponents of this view, often drawing from bin Laden's public statements, argue that addressing these grievances—such as withdrawals—could mitigate such , as evidenced by al-Qaeda's initial focus on the "far enemy" (the U.S.) to weaken local Muslim governments. The tension between these frameworks arises from how grievances are contextualized: while policy advocates treat them as root causes amenable to diplomatic adjustment, ideology proponents contend they serve as religious pretexts within a supremacist that deems any non-Islamic illegitimate, explaining al-Qaeda's simultaneous targeting of "apostate" regimes in , , and alongside U.S. interests. Empirical patterns support the ideological primacy; U.S. withdrawal of combat troops from by September 2003 did not halt al-Qaeda operations, which expanded to attacks like the 2004 bombings and 2005 bombings, driven by calls for global rather than resolved disputes. Captured al-Qaeda communications, including bin Laden's directives, prioritize ideological purity and recruitment through spectacle over policy concessions, revealing a commitment to perpetual conflict until Islamic dominance is achieved. This causal realism underscores that without the supremacist lens—evident in al-Qaeda's fusion with to export revolution—grievances alone fail to explain the scale, persistence, and transnational ambition of the plot, which aimed to provoke a to rally Muslims.

Empirical Evidence from Captured Documents and Interrogations

Captured documents and interrogations of principals consistently identify retaliation against U.S. military presence in , support for , and interventions in as core grievances motivating the . (KSM), captured on March 1, 2003, and interrogated extensively, confessed to masterminding the plot as a means to strike U.S. symbols of power and economy, driven by opposition to American favoritism toward and regional policies perceived as aggressions against Muslims. , in approving KSM's 1996 proposal, linked the operation to his 1998 , which framed the attacks as obligatory against U.S. "occupation" of the —stemming from troop deployments post-1991 —and aid to amid the Palestinian conflict. Declassified analyses of interrogations, including those of KSM and , underscore intent to provoke U.S. overextension, anticipating invasions would drain resources and galvanize global jihadist recruitment, while addressing the third fatwa grievance: U.S.-led sanctions on , blamed for mass civilian deaths. These accounts align with pre-attack al-Qaeda training manuals and operational notes captured in raids, which portrayed Americans as crusaders enabling apostate regimes and justifying spectacular violence to restore Islamic sovereignty. Post-capture documents from bin Laden's 2011 Abbottabad raid reinforce private consistency with public declarations, with letters decrying U.S.-backed Saudi rulers for suppressing reform and tying Palestinian liberation to expelling Western influence from Muslim lands, viewing 9/11 as a pivotal blow to sustain long-term attrition against perceived imperial dominance. Interrogations further reveal ideological layering, where policy objections fused with Salafi-jihadist doctrine mandating warfare on infidels occupying dar al-Islam, aiming not mere destruction but systemic upheaval to impose sharia governance.

Critiques of Western Self-Blame Narratives

Critics contend that narratives framing the September 11 attacks as primarily retaliatory "blowback" from U.S. foreign policy—such as support for Israel or military presence in Saudi Arabia—oversimplify al-Qaeda's motivations by subordinating ideological drivers to geopolitical grievances, thereby excusing jihadist aggression as a predictable response rather than an initiative rooted in religious supremacism. Gilles Kepel, analyzing post-attack commentary, argued that such interpretations erroneously treated the strikes as "the fruit of US policy in Palestine or Iraq," ignoring al-Qaeda's pursuit of a global Salafi-jihadist project aimed at overthrowing apostate regimes and confronting the West irrespective of specific interventions. This view, echoed in works like Paul Berman's Terror and Liberalism, posits jihadism as a totalitarian ideology akin to 20th-century fascism and communism, manifesting hatred for liberal democratic values and secularism, not merely tit-for-tat policy reactions. Al-Qaeda's own declarations underscore this ideological primacy, with Osama bin Laden's 1998 framing the killing of Americans as "an individual duty for every Muslim" to defend against perceived crusader aggression, using policy complaints as religious justifications rather than standalone causes. Lawrence Wright's examination of al-Qaeda's origins reveals a foundational rejection of Western modernity, tracing from Sayyid Qutb's writings decrying U.S. cultural influence as moral corruption to al-Zawahiri's lifelong crusade against secular , indicating that attacks would persist even absent contested policies. Empirical patterns support this: targeted non-U.S. entities like the 1998 U.S. embassy bombings in and plots against , where analogous "imperialist" grievances were absent or minimal, suggesting a broader anti-infidel animus. Such self-blame frameworks, prevalent in certain academic and media circles, have been faulted for systemic reluctance to confront Islamist doctrinal imperatives, potentially inflating source credibility for grievance-centric analyses while marginalizing evidence of captured materials emphasizing eschatological jihad over pragmatic retaliation. For instance, bin Laden's pre-9/11 declarations of war in 1996 preceded escalated U.S. actions like the Iraq no-fly zones, yet invoked eternal religious mandates, implying policy as pretext rather than catalyst. Critics argue this misattribution risks policy paralysis, as historical concessions—such as U.S. withdrawal from in 1993—emboldened rather than deterred al-Qaeda, aligning with patterns where ideological commitment overrides deterrence.
