The Democratic People's Republic of Korea, also called North Korea for short, was a totalitarian socialist state established in 1948 to counter the U.S.-backed Republic of Korea (South Korea). After a series of border clashes with South Korean troops, the North proceeded to invade the South on June 25, 1950. While initially successful in taking most of the South, it faced of the US/SK forces on the city of Pusan in what is now known the Battle of the Pusan Perimeter. The North Koreans knew they could not take Pusan, so KPA General Choi Yong-Kun requested aid from the USSR and China against the adivse of Kim Il-Sung. The two large communist states agreed to intervene and successfully expelled the UN forces from the Korean Peninsula. This led to the Third World War, eventually won by the Soviet Bloc as the U.S.-bloc lost support from its NATO allies. As per agreement of the Sao Paulo Peace Accords, the sovereignty of the Korean Peninsula was given to the DPRK while ROK supporters peacefully relocated to Japan. The victory of the war gave the notion to North Korea, the PRC, and the USSR that capitalism could be defeated and that world revolution is attainable. The Korean People's Army, following the advise of the Soviet Union, sent peacekeepers to Hawaii, British Columbia, Yukon, the Pacific Trust Territories, and the Philippines.
North Korea faced its end during the Purge of the Revisionists when it was invaded by the Soviet Union. The KPA was quickly decimated. Contrary to his belief that he was a living god, Kim Il-Sung, Choi Yong-Kun, and several other KPA generals were executed when the Red Army annexed the Korean Peninsula into the Korean SSR, now part of an ever-mighty Soviet Union.
