korean War
The next event in the Cold War we will focus on is the Korean War. After WWII, USSR and USA split the Korean peninsula into 2 at the 38th parallel. This division was supposed to be temporary untill free elections could be made. However, the USA-USSR relationship soured and both sides started setting up a system that is favourable to them. Then the USSR started to build up military might in North Korea. As such, when USA and USSR left, South Korea had a poorly trained and equipped army while the North had had a well armed and well trained army. When the South threatened to attack the North, North Korea used it as a reason to have a full scale invasion of South Korea. The North Koreans captured most of South Korea. USA became alarmed and sent tropps to reinforce the South Koreans while leading an amphibious attack from Inchon. The US troops managed to push the frontier all the way to the Chinese border. The chinese then became alarmed and sent troops to support the North Koreans. The south started losing and was pushed all the way past Seoul. This is when the US landed more troops and used bombers. They even threatened the use of the atomic bomb. When the the fighting came to a stalemate, the frontier was back at the 38th parallel.
Reflections:
Personally, I think that the Korean War was no ones fault. Both the USA and USSR had to leave the Korean Penisula and neither actively tried to change events. In fact, it was the South Korean president Syngman Rhee for provoking the North Koreans.
