Re: World War 2
He was not better. MacArthur, both in World War 2 and in the Korean War, filled his staff with loyalists who would never question what he said. Indeed, anyone who disagreed with him was rapidly pushed aside without consideration.
MacArthur refused to allow the OSS (later the CIA) to operate in the Pacific Theatre and in Korea because he wanted only the intelligence reports that he approved of to reach the president. Intelligence that he did not approve of (such as the fact that massive numbers of Chinese troops were about to join the Korean War) was surpressed because it was not convenient to the version of the story that MacArthur wanted to put out!
