The statement that best describes why in 1951, President Truman decided to fire General Douglas MacArthur is “MacArthur had publicly criticized Truman’s approach to the war”.
General Douglas MacArthur was fired because of his insubordination. General MacArthur had the plan to bomb the People's Republic of China, but President Eisenhower was against it and General MacArthur opposed the command-in-chief. That’s why he was fired for insubordination.
