Patton was not too PC. He called them as he saw them. He was the best allied general, far ahead of Eisenhower and Montgomery. His political candor prevented him from getting too far with the high command. He was wanting to go on toward Moscow and capturing Stalin. The world would have been far better off if his advice had been folllwed.
Patton was fortunate that he didn't have to live too long after WWII. I don't think he could have stomached the complete surrender of E Europe to the Soviets.
