USA HISTORY

Detailed explanation-1: -Concerned that the Soviet Union and Communist China might have encouraged this invasion, President Harry S. Truman committed United States air, ground, and naval forces to the combined United Nations forces assisting the Republic of Korea in its defense.

Detailed explanation-2: -America wanted not just to contain communism-they also wanted to prevent the domino effect. Truman was worried that if Korea fell, the next country to fall would be Japan, which was very important for American trade. This was probably the most important reason for America’s involvement in the war.

Detailed explanation-3: -The Korean War was difficult to fight and unpopular domestically. In late 1951, the two sides bogged down on the 38th parallel, and the conflict seemed reminiscent of trench warfare in World War I. The American public tired of a war without victory, especially when negotiation stalled as well.

Detailed explanation-4: -Truman and his advisors found themselves under increased domestic pressure not to appear “soft” on communism abroad. Thus, when North Korean troops invaded the South, the Truman administration seized upon the opportunity to defend a non-communist government from invasion by communist troops.
