Central Treaty Organization

The Central Treaty Organization (CENTO), formerly known as the Middle East Treaty Organization (METO) and also known as the Baghdad Pact, was a military alliance of the Cold War. It was formed on 24 February 1955 by Iran, Iraq, Pakistan, Turkey, and the United Kingdom. The alliance was dissolved on 16 March 1979.

U.S. pressure and promises of military and economic aid were key in the negotiations leading to the agreement, but the United States could not initially participate. John Foster Dulles, who was involved in the negotiations as United States Secretary of State under President Dwight D. Eisenhower, claimed that was due to "the pro-Israel lobby and the difficulty of obtaining Congressional Approval." Others said that the reason was "for purely technical reasons of budgeting procedures."

In 1958, the U.S. joined the military committee of the alliance. It is generally viewed as one of the least successful of the Cold War alliances.

The organization's headquarters was in Baghdad, Iraq from 1955 to 1958 and thereafter in Ankara, Turkey from 1958 to 1979. Cyprus was also an important location for CENTO due to the British military bases in Akrotiri and Dhekelia along with the island’s location in the Middle East.

Modeled after the North Atlantic Treaty Organization (NATO), METO committed the nations to mutual cooperation and protection, as well as non-intervention in each other's affairs. Its goal was to contain the Soviet Union (USSR) by having a line of strong states along the Soviet Union's southwestern frontier. Similarly, it was known as the 'Northern Tier' to prevent Soviet expansion into the Middle East. Unlike NATO, METO did not have a unified military command structure, nor were many American or British military bases established in member countries, although the United States had communications and electronic intelligence facilities in Iran, and operated U-2 intelligence flights over the Soviet Union from bases in Pakistan. The United Kingdom had access to facilities in Pakistan and Iraq at various times while the treaty was in effect.

On 14 July 1958, the Iraqi monarchy was overthrown in a military coup. The new government was led by military officer Abd al-Karim Qasim who withdrew Iraq from the Baghdad Pact, opened diplomatic relations with Soviet Union and adopted a non-aligned stance. The organization dropped the name 'Baghdad Pact' in favor of 'CENTO' at that time.

The Middle East and South Asia became extremely volatile areas during the 1960s with the ongoing Arab–Israeli conflict and the Indo-Pakistani wars. CENTO was unwilling to get deeply involved in either dispute. In 1965 and 1971, Pakistan unsuccessfully tried to get assistance in its wars with India through CENTO, but this was rejected under the idea that CENTO was aimed at containing the Soviet Union, not India.

CENTO did little to prevent the expansion of Soviet influence to non-member states in the area. Whatever containment value the pact might have had was lost when the Soviets 'leap-frogged' the member states, establishing close military and political relationships with governments in Egypt, Syria, Iraq, South Yemen, Somalia, and Libya. By 1970, the Soviet Union had deployed over 20,000 troops to Egypt, and had established naval bases in Syria, Somalia, and South Yemen.
