We watched a movie on North and South Korea war in history class. At that time, lots of people are dying. Some of them are forced to join the war as soldiers. The Chinese and Americans join the war. The reason that US helps South Korea is because they want them to stay democracy. The US are nervous about communist because they felt that communist are like dominos. They'll spread out and finally control the whole world. The reason that Chinese helps North Korea is because they like communist and because the US troops push South Korea upward near the China border. After the war, North and South Korea stays separate between 38th parallel.
