During the Korean War it was a battle between South Korean and North Korea. The North wanted to take over all of Korea and change it into a communist country. Of course America would not let this go and intervened preventing North Korea to advance any further by launching a counterattack at Inchon. This pushed the North Koreans back to the border between the North and South of Korea.
I think that if America never intervene during the Korean War the world today would be very different. Communism would have spread through all of Korea turning it into a communist country. I think that it would have caused a Domino Effect causing other counties turning communist. The way this would impact my life is that I would be in great fear. I would be afraid that communism would spread world wide and eventually hit America.
The Korean War created more tension between the United States and the Soviet Union during the Cold War. The war showed that the United States would try everything possible to prevent the spread of communism. The Korean War never ended, the two sides were unable to resolve their differences.
