Anti-communismAnti-communism is political and ideological opposition to communist beliefs, groups, and individuals. Organized anti-communism developed after the 1917 October Revolution in the Russian Empire, and it reached global dimensions during the Cold War, when the United States and the Soviet Union engaged in an intense rivalry. Anti-communism has been an element of many movements and different political positions across the political spectrum, including anarchism, centrism, conservatism, fascism, liberalism, nationalism, social democracy, socialism, leftism, and libertarianism, as well as broad movements resisting communist governance.
DétenteDétente; detɑ̃t) is the relaxation of strained relations, especially political ones, through verbal communication. The diplomacy term originates from around 1912, when France and Germany tried unsuccessfully to reduce tensions. The term is often used to refer to a period of general easing of geopolitical tensions between the Soviet Union and the United States during the Cold War. Détente began in 1969 as a core element of the foreign policy of United States President Richard Nixon.
Carter DoctrineThe Carter Doctrine was a policy proclaimed by President of the United States Jimmy Carter in his State of the Union Address on January 23, 1980, which stated that the United States would use military force, if necessary, to defend its national interests in the Persian Gulf. It was a response to the Soviet Union's intervention in Afghanistan in 1979, and it was intended to deter the Soviet Union, the United States' Cold War adversary, from seeking hegemony in the Persian Gulf region.
RollbackIn political science, rollback is the strategy of forcing a change in the major policies of a state, usually by replacing its ruling regime. It contrasts with containment, which means preventing the expansion of that state; and with détente, which means a working relationship with that state. Most of the discussions of rollback in the scholarly literature deal with United States foreign policy toward communist countries during the Cold War. The rollback strategy was tried and was not successful in Korea in 1950 and in Cuba in 1961, but it was successful in Grenada in 1983.
Harry S. TrumanHarry S. Truman (May 8, 1884 December 26, 1972) was the 33rd president of the United States, serving from 1945 to 1953. A member of the Democratic Party, he previously served as the 34th vice president from January to April 1945 under Franklin D. Roosevelt and as a United States senator from Missouri from 1935 to January 1945. Assuming the presidency after Roosevelt's death, Truman implemented the Marshall Plan to rebuild the economy of Western Europe and established both the Truman Doctrine and NATO to contain the expansion of Soviet communism.
Deterrence theoryDeterrence theory refers to the scholarship and practice of how threats or limited force by one party can convince another party to refrain from initiating some other course of action. The topic gained increased prominence as a military strategy during the Cold War with regard to the use of nuclear weapons and is related to but distinct from the concept of mutual assured destruction, according to which a full-scale nuclear attack on a power with second-strike capability would devastate both parties.
Greek Civil WarThe Greek Civil War (ο Eμφύλιος [Πόλεμος], o Emfýlios [Pólemos], "the Civil War") took place from 1946 to 1949. The conflict, which erupted shortly after the end of World War II, consisted of a communist-dominated uprising against the established government of the Kingdom of Greece. The opposition declared a people's republic, the Provisional Democratic Government of Greece, which was governed by the Communist Party of Greece (KKE) and its military branch, the Democratic Army of Greece (DSE).
Reagan DoctrineThe Reagan Doctrine was stated by United States President Ronald Reagan in his State of the Union address on February 6, 1985: "We must not break faith with those who are risking their lives—on every continent from Afghanistan to Nicaragua—to defy Soviet-supported aggression and secure rights which have been ours from birth." It was a strategy implemented by the Reagan Administration to overwhelm the global influence of the Soviet Union in the late Cold War.
Gulf of Tonkin incidentThe Gulf of Tonkin incident (Sự kiện Vịnh Bắc Bộ) was an international confrontation that led to the United States engaging more directly in the Vietnam War. It consisted of a confrontation on August 2, 1964, when United States forces were carrying out covert operations close to North Vietnamese territorial waters and North Vietnamese forces responded. The United States government falsely claimed that a second incident occurred on August 4, 1964, between North Vietnamese and United States ships in the waters of the Gulf of Tonkin.
Domino theoryThe domino theory is a geopolitical theory which posits that increases or decreases in democracy in one country tend to spread to neighboring countries in a domino effect. It was prominent in the United States from the 1950s to the 1980s in the context of the Cold War, suggesting that if one country in a region came under the influence of communism, then the surrounding countries would follow. It was used by successive United States administrations during the Cold War as justification for American intervention around the world.
