USA HISTORY

Detailed explanation-1: -Truman had to decide whether to intervene in the Korean War. Truman’s deliberations were guided by the principles of containment policy of the early Cold War. Facing postwar expansion by the Soviet Union in Asia, the Middle East, and Europe, Truman and his foreign policy advisors developed the idea of containment.

Detailed explanation-2: -Containment-The korean war: from containment to liberation to containment. The Korean War led to the endorsement of NSC 68, vast expenditures for arms in Asia and in Europe, and the overextension of American power. American intervention in Korea was the most dramatic test to that date for containment.

Detailed explanation-3: -The temporary division of Korea along the 38th parallel was a success for the policy of containment, as communism did not spread into South Korea. In 1954, SEATO (South East Asian Treaty Organisation) was set up as a copy of NATO. Communism had been prevented in South Korea and the UN was seen as a success.

Detailed explanation-4: -More generally, the Truman Doctrine implied American support for other nations threatened by Moscow. It became the foundation of American foreign policy, and led, in 1949, to the formation of NATO, a military alliance that still exists. Historians often use Truman’s speech to date the start of the Cold War.
