McArthur was surrounded by patsies that were unwilling to give him the real poop. He was ok with that because he didn’t want to hear anything that would dissuade from his firmly held belief that Chang Kai Shek was China and had an army of 500,00 warriors.
Douglas ended up a colossal failure as a military commander.
Mac may have been a bit of a “perfumed prince” but he fared better than Patton as things turned out; Far from a failure.
Patton actually outranked Ike at the close of WWII, due to his wartime rank/promotions remained RA, whereas Ike’s were US rank/promotion and to be reverted to actual RA rank.
Anyway, Patton failed only due to his questionable demise and failure to become POTUS. He had intended to resign not retire from the Army.
Such is life, politics, etc.
