Truman Doctrine in the context of "Cold War"

The Turkish Straits crisis was a Cold War–era territorial conflict between the Soviet Union and Turkey. Turkey had remained officially neutral throughout most of the Second World War. After the war ended, Turkey was pressured by the Soviet government to institute joint military control of passage through the Turkish Straits, which connected the Black Sea to the Mediterranean. When the Turkish government refused, tensions in the region rose, leading to a Soviet show of force and demands for territorial concessions along the Georgia–Turkey border.

This intimidation campaign was intended to preempt American influence or naval presence in the Black Sea, as well as to weaken Turkey's government and pull it into the Soviet sphere of influence. The Straits crisis was a catalyst, along with the Greek Civil War, for the creation of the Truman Doctrine. At its climax, the dispute would motivate Turkey to turn to the United States for protection through NATO membership.

Harry S. Truman (May 8, 1884 – December 26, 1972) was the 33rd president of the United States, serving from 1945 to 1953. As the 34th vice president in 1945, he assumed the presidency upon the death of Franklin D. Roosevelt that year. Subsequently, Truman implemented the Marshall Plan in the aftermath of World War II to rebuild the economy of Western Europe, and established both the Truman Doctrine and NATO to contain the expansion of Soviet communism. A member of the Democratic Party, he proposed numerous New Deal coalition liberal domestic reforms, but few were enacted by the conservative coalition that dominated the United States Congress.

Born in Lamar, Missouri, Truman was raised in Independence, Missouri, and during World War I fought in France as a captain in the Field Artillery. Returning home, he opened a haberdashery in Kansas City, Missouri, and was elected as a judge of Jackson County in 1922. Truman was elected to the U.S. Senate for Missouri in 1934. Between 1940 and 1944, he gained national prominence as the chairman of the Truman Committee, which aimed to reduce waste and inefficiency in wartime contracts. Truman was elected vice president in the 1944 presidential election and became president upon Roosevelt's death in April 1945. Only then was he told about the ongoing Manhattan Project and the atomic bomb. Truman authorized the first and only use of nuclear weapons in war against the Japanese cities of Hiroshima and Nagasaki.

Counter-Guerrilla (Turkish: Kontrgerilla) is a Turkish branch of Operation Gladio, a clandestine stay-behind anti-communist initiative backed by the United States as an expression of the Truman Doctrine. The founding goal of the operation was to erect a stay-behind guerrilla force to undermine a possible Soviet occupation. The goal was soon expanded to subverting communism in Turkey.

The Counter-Guerrilla initially operated out of the Turkish Armed Forces' Tactical Mobilization Group (Turkish: Seferberlik Taktik Kurulu, or STK). In 1967, the STK was renamed to the Special Warfare Department (Turkish: Özel Harp Dairesi, ÖHD). In 1994, the ÖHD became the Special Forces Command (Turkish: Özel Kuvvetler Komutanlığı, ÖKK).

The participation of the United States in regime change in Latin America involved U.S.-backed coup d'états which were aimed at replacing left-wing leaders with right-wing ones, military juntas, or authoritarian regimes. Intervention of an economic and military variety was prevalent during the Cold War. Although originally in line with the Truman Doctrine of containment, United States involvement in regime change increased following the drafting of NSC 68, which advocated more aggressive actions against potential Soviet allies.

In the early 20th century, during the "Banana Republic" era of Latin American history, the U.S. launched several interventions and invasions in the region (known as the Banana Wars) in order to promote American business interests. United States influenced regime change in this period of Latin American history which started after the signing of the Treaty of Paris in the wake of the Spanish–American War. Cuba gained its independence, while Puerto Rico was annexed by the United States. Expansive and imperialist U.S. foreign policy combined with new economic prospects led to increased U.S. intervention in Latin America from 1898 to the early 1930s. Continued activities lasted into the late 20th century.

George Frost Kennan (February 16, 1904 – March 17, 2005) was an American diplomat and historian. He was best known as an advocate of a policy of containment of Soviet expansion during the Cold War. He lectured widely and wrote scholarly histories of the relations between the USSR and the United States. He was also one of the group of foreign policy elders known as "The Wise Men".

During the late 1940s, his writings confirmed the Truman Doctrine and inspired the U.S. foreign policy of containing the USSR. His "Long Telegram" from Moscow in 1946 and the subsequent 1947 article "The Sources of Soviet Conduct" argued that the Soviet regime was inherently expansionist and that its influence had to be "contained" in areas of vital strategic importance to the United States. These texts provided justification for the Truman administration's new anti-Soviet policy. Kennan played a major role in the development of definitive Cold War programs and institutions, notably the Marshall Plan.

The involvement of the United States in the Vietnam War began in the 1950s and greatly escalated in 1965 until its withdrawal in 1973. The U.S. military presence in Vietnam peaked in April 1969, with 543,000 military personnel stationed in the country. By the end of the U.S. involvement, more than 3.1 million Americans had been stationed in Vietnam, and 58,279 had been killed.

After World War II ended in 1945, President Harry S. Truman declared his doctrine of "containment" of communism in 1947 at the start of the Cold War. U.S. involvement in Vietnam began in 1950, with Truman sending military advisors to assist the French Union against Viet Minh rebels in the First Indochina War. The French withdrew in 1954, leaving North Vietnam in control of the country's northern half. President Dwight D. Eisenhower ordered covert CIA activities in South Vietnam. Opposition to the regime of Ngo Dinh Diem in South Vietnam was quashed with U.S. help, but from 1957 insurgents known as the Viet Cong launched a campaign against the state. North Vietnam supported the Viet Cong, which began fighting the South Vietnamese army. President John F. Kennedy, who subscribed to the "domino theory" that communism would spread to other countries if Vietnam fell, expanded U.S. aid to South Vietnam, increasing the number of advisors from 900 to 16,300, but this failed to produce results. In 1963, Diem was deposed and killed in a military coup tacitly approved by the U.S. North Vietnam began sending detachments of its own army, armed with Soviet and Chinese weapons, to assist the Viet Cong.
