Is what some of the GIs called him, presumably because of his ability to stay out of the line of fire. Whether that is a fair assessment, or even a common one at the time, I really do not know, and I will suspend my judgement.

He was certainly an egotistical man, one very concerned with "publicity". But whether the criticisms or praises heaped on him were justified I really cannot tell. Maybe they were both justified. He did win the war in the Pacific, that cannot be denied, and victory is the only judgement that matters. Still, it was primarily a Naval conflict.

The rest of what I know about MacArthur is spotty. I know he was in command when the WWI veterans agitating for their pensions were routed at bayonet point, one of the most shameful episodes in American history. But can he be blamed for that? He had his orders. His attack at Inchon was a brilliant maneuver, but also incredibly risky. He might have led our forces into a humiliating disaster, another Dunkirk, at best. At worst, a total rout. But instead it led to a collapse of the enemy, and in war, it is the result that matters, not the possibilities.

But shortly after that triumph, he uttered the remarks that eventually led the Chinese to enter Korea, so that great Inchon victory was nullified. Truman was perfectly right, and highly courageous himself, in firing his ass.
