State Sponsors of Terrorism

"State Sponsors of Terrorism" is a designation applied to countries that are alleged to have "repeatedly provided support for acts of international terrorism" per the United States Department of State. Inclusion on the list enables the United States government to impose four main types of unilateral sanctions: a restriction of foreign aid, a ban on weapons sales, heightened control over the export of dual-use equipment, and other miscellaneous economic sanctions. The State Department is required to maintain the list under section 1754(c) of the National Defense Authorization Act for Fiscal Year 2019, section 40 of the Arms Export Control Act, and section 620A of the Foreign Assistance Act.

In 1979, the first such list was published by the State Department, designating Iraq, Libya, South Yemen, and Syria as terrorist states. As of 2025^[update], the list consists of Cuba, Iran, North Korea, and Syria. The countries that were once on the list but have since been removed are: Iraq, Libya, South Yemen (dissolved in 1990), and Sudan. A resolution concerning the addition of Russia to the list was introduced to the Senate following the Russian invasion of Ukraine in 2022.

Cuba was added to the list on March 1, 1982, on the basis that it has a history of supporting revolutionary movements in Spanish-speaking countries and Africa.

Havana openly advocates armed revolution as the only means for leftist forces to gain power in Latin America, and the Cubans have played an important role in facilitating the movement of men and weapons into the region. Havana provides direct support in the form of training, arms, safe havens, and advice to a wide variety of guerrilla groups. Many of these groups engage in terrorist operations.

According to the U.S. Department of State, Cuba "encouraged terrorism in the hope of provoking indiscriminate violence and repression, in order to weaken government legitimacy and attract new converts to armed struggle." In 1992, after the Soviet collapse, Fidel Castro stressed that his country's support for insurgents abroad was a thing of the past.

According to Country Reports on Terrorism 2010: August 18, 2011:

Designated as a State Sponsor of Terrorism in 1982, the Government of Cuba maintained a public stance against terrorism and terrorist financing in 2010, but there was no evidence that it had severed ties with elements from the Revolutionary Armed Forces of Colombia (FARC) and recent media reports indicate some current and former members of the Basque Fatherland and Liberty (ETA) continue to reside in Cuba. Available information suggested that the Cuban government maintained limited contact with FARC members, but there was no evidence of direct financial or ongoing material support. In March, the Cuban government allowed Spanish Police to travel to Cuba to confirm the presence of suspected ETA members. Cuba has been used as a transit point by third-country nationals looking to enter illegally into the United States. The Government of Cuba is aware of the border integrity and transnational security concerns posed by such transit and investigated third country migrant smuggling and related criminal activities. In November, the government allowed the Transportation Security Administration representatives to conduct a series of airport security visits throughout the island. Regional and International Cooperation: Cuba did not sponsor counterterrorism initiatives or participate in regional or global operations against terrorists in 2010.

On December 17, 2014, an agreement to restore relations with Cuba was reached (Cuban thaw); President Barack Obama instructed the Secretary of State to immediately launch a review of Cuba's inclusion on the list, and provide a report to the President within six months regarding Cuba's alleged support for international terrorism. President Barack Obama announced on April 14, 2015, that Cuba was being removed from the list. Cuba would not come off the list until after a 45-day review period, during which the U.S. Congress could try blocking Cuba's removal via a joint resolution. Congress did not act, and Cuba was officially removed from the list on May 29, 2015.
