What happened to Douglas MacArthur during the Korean War?

• A. He was relieved by President Truman for publicly challenging policy and seeking to strike China.
• B. He was promoted and given wider authority to lead the war in Asia.
• C. He retired after a ceremonial farewell with no conflict.
• D. He led a successful invasion of China.

Answer: (A)

Civilian control of the military and the boundaries of war policy are in play here. MacArthur was commanding UN forces in Korea and had achieved early gains, but he began to push for broader actions—advocating an invasion of China and even suggesting the use of nuclear weapons. He publicly challenged the administration’s Korea strategy, crossing from military advice into political policy and undermining the authority of the civilian leadership. That clash over who makes war decisions led President Truman to relieve him from command in 1951. The other statements don’t fit what happened: he wasn’t promoted, didn’t retire after a ceremonial farewell, and didn’t lead a successful invasion of China.
