USA HISTORY

Detailed explanation-1: -The United States came to the aid of South Korea at the head of a United Nations force composed of more than a dozen countries. Communist China joined North Korea in the war in November 1950, unleashing a massive Chinese ground attack against American forces.

Detailed explanation-2: -The U.S.-ROK Mutual Defense Treaty, signed in 1953 at the end of the Korean War, commits the United States to help South Korea defend itself, particularly from North Korea (officially the Democratic People’s Republic of Korea, or DPRK). Approximately 28, 500 U.S. troops are based in the ROK.

Detailed explanation-3: -Relations between North Korea and the United States have been historically tense and hostile, as both countries have no diplomatic relations. The Swedish Embassy in Pyongyang is the U.S. protecting power and provides limited consular services to U.S. citizens.

Detailed explanation-4: -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-5: -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.
