Why did the United States enter the Korean War?
The US Army had been in Korea since the end of World War II, when it was given up by the Japanese, with all the rest of Japan’s colonies. Korea was split into two spheres of influence, with the Soviets controlling the North and the Americans the South. When the war broke out in 1950, American troops were still in the South when the invasion came, so naturally they defended the anti-communist regime against the North Korean army. This is why there was no one vote to go to war in Korea, America was there when the war began. Truman decided to continue the defense by sending more troops and to attempt to recapture South Korea even when it looked as though the North would win. This was done because the United States wanted to make a point that it would not allow further communist expansion by conquest, and would go to war again to prove it.
