Because he was an arrogant prima donna who surrounded himself with toadies. The antithesis of Omar Bradley in a general officer.
On Dec 7, 1941, how many valor awards did Bradley have versus MacArthur?
Wasn't Bradley known for sacking his generals?
Bradley sacked Terry Allen and Theodore Roosevelt Junior from the Big Red One, in Sicily. He sacked others. He was also Ike’s stoolie in II Corps when Patton was the CG.
And good old Brad honed his “Infantryman’s General” persona with as much of a vengeance as Pistol Packin’ Georgie did with his. But at least his mother never lobbied for him [including pushing for medals in WW I] like Dougie’s did.
I will concede that Bradley lacked MacArthur’s self-promotional skills and had only a fraction of his ego.
