At the end of World War II, the Soviet Union and the United States divided up the Korean Peninsula, formerly a Japanese colonial possession, along the 38th parallel, setting up a communist government in the north and a pro-Western, anti-communist government in the south. North Korean leader Kim Il Sung visited Stalin in March 1949 and again in March 1950; he wanted to invade the south, and although Stalin was initially reluctant to provide support, he eventually agreed by May 1950. The North Korean Army launched the Korean War by invading South Korea in June 1950, making swift gains and capturing Seoul. Both Stalin and Mao believed that a swift victory would ensue. The U.S. went to the UN Security Council—which the Soviets were boycotting over its refusal to recognise Mao's government—and secured international military support for the South Koreans. U.S. led forces pushed the North Koreans back. Stalin wanted to avoid direct Soviet conflict with the U.S., and convinced the Chinese to enter the war to aid the North in October 1950.
