korean War
The Korean war was the first proxy war that the U.S were involved in. The war started when the North tried to take over the South. At this point North Korea was a communist country and South Korea was a democratic country. North Korea was able to push South Korea to the coast, but when the U.S stepped in they pushed North Korea out of South Korea, and kept pushing until they reached the Chinese border. China then pushed us back down to where North Korea and South Korea border each other. A guy named Douglas MacArthur tried to convince Truman to drop a nuke on China, because it would get rid of one of the communist countries and end the Cold War, but Truman refused the idea because he didn't want to start WWIII. In the end of the Korean war the U.S ended up losing 50,000 people and Korea ended up losing around 4,000,000 people.
