U.S. entering the Korean War

With the Korea Peninsula now divided between a Soviet-backed government in the north and an American-backed government in the south tensions were quickly rising. It was only a matter of time before the ideologies of both countries were going to be put to the test. The United States was afraid that the Soviet backed North would soon try to invade the entire peninsula, and they were right. Their ideologies involved aggressive military action for control, while ours involved necessary action for protection, so obviously there was bound to be conflict. The United States policy of Containment states that the US will help any country that is being threatened with communism. North Korean troops coordinated attacks on sever places along the parallel and began a movement toward Seoul, this is the reason the United states entered the conflict.
