Who was the overall commander of the United Nations forces during the Korean War?

The overall commander of the United Nations forces during the Korean War was General Douglas MacArthur. He played a crucial role in orchestrating the military strategy and operations for the UN coalition that intervened in Korea following North Korea's invasion of the South in June 1950. MacArthur's leadership was pivotal during several key battles, including the successful amphibious assault at Inchon, which turned the tide in favor of the UN forces. His approach and decisions had significant impacts on the course of the war, and although his command was later mired in controversy, particularly regarding his views on China's involvement, his initial military successes established him as a prominent figure in the conflict. The other figures listed did not serve as commanders for the UN forces during this specific conflict, as they were involved in different capacities during different wars or time periods.
