During the Second World War Japan had formed an alliance with Germany and stretched out its influence in Asia. After Germany and Japan had to capitulate unconditionally in 1945 Korea, a previously occupied country was divided into two occupation zones. While the USA occupied the south, the Soviet Union controlled the north, establishing two opposing ideologies in the occupation zones. The Soviet Union proclaimed a socialistic republic in North Korea while the USA established democracy in the south as a counterweight to the Soviet influence in the north. When the North Korean army breached the South Korean borders in 1950 and attacked American air force bases the UN Security CouncilThe aim of the United Nations Security Council is the establishment of peacekeeping operations, the establishment of international sanctions, and the authorization of military action reacted with a military intervention of the United Nations1.
Course of the war
While the North Korean forces, supported by the United Nations, invaded the North the Chinese and the Soviets, united in a communistic bond, got involved in the war using airplanes and soldiers. In the spring of 1951 North Korea increased the pressure on the South and, with Chinese help, forced the UN and US troops to retreat. In the autumn of the same year both sided increased the use of bombs in warfare, leading to a high number of victims and combat fatigue. After the war had developed into positional warfare, North Korea and the United Nations agreed on a ceasefire in July 1953.
Until today the conflict between North and South Korea concerning the border of the 38th degree of latitude has not ceased. Ever since the Korean War several divergences between the USA and China arose as China had supported the Soviet Union in the war. Moreover the Korean War led to an increased armament in the USA as well as in the Soviet Union, exacerbating the global conflict, nowadays known as the cold war.
Recently found defence alliances (NATO, Warsaw PactThe Warsaw Pact was a collective defense treaty among eight communist states of Central and Eastern Europe in existence during the Cold War) divided the world into the Eastern and Western power bloc2.
