Two Koreas and two completely different governments lead to one deadly war. The Korean War is sometimes referred as the "Forgotten War." Since the 1400's either Japan or China has conquered Korea. From 1910 to 1945, Korea was completely under Japanese control. Then, after World War II Korea was on its own. The people had no government, no money, and no navy or army to protect their country. Due to the lack of organization that Korea had, it sparked attention from other powerful nations to conquer.
On January 12, 1950, the U.S. Secretary of State, Dean Acheron, addressed the National Press Club in Washington D.C. He made the announcement that, in the line with the U.S. policy of containing communism in a certain geographical boundaries. The defense perimeter in the Pacific would run from Aleutians, off Alaska, down Japan, the Ryukyu's Islands and the Philippines. The countries lying beyond the perimeter would have to rely upon their own resources to prevent any communist advances. To the Korean people this meant that the fate of their country was to be left to them.
The speech was greeted with horror by the government of South Korea. The government feared that the military power of the communist government would take over the Democratic republic of North Korea. The North Korean government believed that the refusing of the country under communist control could be achieved without interference of the United States. On June 25, the United States was caught unprepared. As the North Korean troops advanced into the South to meet with the anti-government forces within the country. The United States President Harry S. Truman met up with his advisors to decide what to do. The policy formed a few months earlier was reversed and the United States pledged to provide military support to the government in the South.
The Korean City of Pusan was very important during the Korean War. It was a perfect place for the United States military force to land troops and supplies and to use as a base for carrying on a war in Korea.
