8 September – On this day
U.S. troops land in Korea to begin their postwar occupation of the southern part of that nation, Soviet troops had already entered northern Korea to begin their own occupation. Although the U.S. and Soviet occupations were supposed to be temporary, the division of Korea quickly became permanent.
Soviet troops withdrew in 1948, having established a communist government in North Korea, and U.S. troops in South Korea followed suit in 1949. In 1950, the North Koreans attempted to reunite the nation by force and launched a massive military assault on South Korea. The United States quickly came to the aid of South Korea, beginning a three-year involvement in the bloody and frustrating Korean War. Korea remains a divided nation today, and the North Korean regime is one of the few remaining communist governments left in the world.
