Two of the immediate effects of The Korean War are that it was one of the most destructive of the 20th century, and The Korean War also brought social damage to Korea, especially in the North. North Korea remained a communist nation and South Korea became a free republic. This social difference still brings conflict even today. . However, the Korean War was able to boost the economy of both Japan and the US. The Korean War also legitimized the United Nations and led to further expansion of military power. The war had a lasting consequence beyond Korea. Much of the material used in the war was bought from nearby Japan. This gave Japanese economy such an dynamic boot after the ravages of WWII that some have called the Korean War, also it had similar effects on the American economy, as defense spending nearly quadrupled in the last six months of 1950.
Truman wanted to go to war with North Korea by himself but decided that he cannot act alone without UN support. Truman saw this as a test for containment and he later went to the UN and he asked for help. The UN approve sending troops to help defend South Korea from North Korea. After that, Britain, Australia, Canada, Columbia, Turkey, New Zealand, and other nations were among the UN to help out the US and South Korea against the North Korea aggression. The war went on for 3 years and UN successfully defend South Korea from North Korea aggression.
The U.S sent troops to south korea and the united nations backed them up and they went against north korea and fought them.across the 38th parallel and pushed them up to the yalu river on the boarder of china and the UN captured pyongyang north korean capital and china was pissed because the u.s and UN went to china border so china pushed them back to south korea over the 38th parallel and to prevent ww3 everything went back to where it started and nations north and south went back to where they started and left it at that. The president’s “Truman Doctrine” committed the United States to a policy of supporting foes of Communism everywhere in the world. Truman’s failure to lead the United States to victory in the Korean War led to a severe decline in support for the president’s policies among the American people.
