One of Carter's first acts was to order the withdrawal of troops from South Korea, which had hosted a large number of U.S. military personnel since the end of the Korean War. Carter believed that the soldiers could be put to better use in Western Europe, but opponents of the withdrawal feared that North Korea would invade South Korea in the aftermath of the withdrawal. South Korea and Japan both protested the move, as did many members of Congress, the military, and the State Department. After a strong backlash, Carter delayed the withdrawal, and ultimately only a fraction of the U.S. forces left South Korea. Carter's attempt to remove U.S. forces from South Korea weakened the government of South Korean President Park Chung-hee, who was assassinated in 1979.
