The decision to intervene in Korea grew out of the tense atmosphere that characterized Cold War politics. On the eve of the North Korean invasion, a number of events had made Truman anxious. The Soviet Union exploded an atomic bomb in 1949, ending the United States' monopoly on the weapon. In Europe, Soviet intervention in Greece and Turkey had given rise to the Truman Doctrine and the Marshall Plan, which funneled aid to war-torn Europe in the hopes of warding off communist political victories. In early 1950, President Truman directed the National Security Council (NSC) to conduct an analysis of Soviet and American military capabilities. In its report, known as "NSC 68," the Council recommended heavy increases in military funding to help contain the Soviets.

Thus, when North Korean troops invaded the South, the Truman administration seized upon the opportunity to defend a noncommunist government from invasion by communist troops. Determined not to "lose" another country to communism, and interested in shoring up its anticommunist credentials, the Truman administration found itself defending a nation a world away from U.S. soil. Yet Truman's response was not merely a response to internal pressure. The invasion of South Korea made Truman genuinely fearful that the Soviet Union and China intended to expand the sphere of communism throughout Asia.

Truman's statement of June 27 illustrates his concern with communist aggression and expansion. In it, Truman argues that "communism has passed beyond the use of subversion to conquer independent nations and will now use armed invasion and war." Truman's statement suggests that he believed the attack by North Korea had been part of a larger plan by communist China and, by extension, the Soviet Union. The President believed that the Korean situation was similar to that of Greece in 1947. He informed his advisors that he believed the invasion was "very obviously inspired by the Soviet Union." This gave America a moral imperative to act. "If we don't put up a fight now," Truman observed to his staff, there was "no telling what they'll do." His concern over the future of anticommunist governments in Asia showed in his public statement. Truman pledged to defend Formosa (Taiwan) from attack and to support French forces in Indochina, a conflict that would eventually escalate into the Vietnam War. Yet Truman had no wish to provoke a full-scale war with the Soviets. By blaming "communism" in the statement, as opposed to the Soviet Union, Dean Acheson later explained, the administration sought to give the Soviets a "graceful exit" and not provoke open confrontation with Russia.

Truman's statement also reflected a new military order. Although the United States took the lead in the Korean action, it did so under the rubric of the United Nations. Truman made it clear that his actions fell within the measures recommended by the United Nations, and reminded "all members of the United Nations" to "consider carefully the consequences of this latest aggression in Korea" and that America "will continue to uphold the rule of law."

The Cold War shaped American foreign policy and political ideology, impacted the domestic economy and the presidency, and affected the personal lives of Americans creating a climate of expected conformity and normalcy. By the end of the 1950's, dissent slowly increased reaching a climax by the late 1960's.

Explanation:

The Cold War brought about changes to the presidency of the United States. Internal and external forces influenced those changes. Internally, Truman's hard-line stand against Stalin put enough pressure on his administration to affect many presidential acts. Externally, politicians used anti-communist hysteria to campaign on a strong, rightist platform, occasionally accusing the current administration of softness in order to improve their lot. In one instance Robert Taft blamed Truman for seeking a congress "dominated by a policy of appeasing the Russians abroad and of fostering communism at home." (2) American foreign policy became one of containment as it reacted to the Cold War. As the mutual confidence of the two nations weakened, a kind of chess game evolved using the world map as its board. The United States supported corrupt and anti-democratic governments, but friendly to America. Meanwhile, the Soviets subsidized groups favorable to their own interest.
