Operation Blacklist Forty was the codename for the United States occupation of Korea between 1945 and 1948. Following the end of World War II, US forces landed within the present-day South Korea to accept the surrender of the Japanese, and help create an independent and unified Korean government with the help of the Soviet Union, which occupied the present-day North Korea. However, when this effort proved unsuccessful, the United States and the Soviet Union both established their own friendly governments, resulting in the current division of the Korean Peninsula.
