My opinion on Patton is based pretty much on his military merit.
Consider - if there were a politician running for election who supported almost all the issues you supported, wouldn’t you be willing to give him a lot of leeway on his personal life? At least, this is my taste when it comes to powerful figures. For example, I am willing to overlook Bill Clinton’s sexual indiscretions when I try to measure whether or not he was a successful president.
So before I move on, I guess I should discuss the character flaws I’m going to overlook.
Patton had, in my opinion, a large number of character deficits. He was often stubborn and arrogant, had difficulty compromising, and held others to a nearly impossible standard.
He believed that he was the reincarnation of ancient military figures. (For me, this is a deficit, make of it what you will)
He made numerous political blunders that had to be cleaned up, sometimes, according to some historians, accidentally divulging secret information.
Now, all the being said, let us consider his value to the American military:
Here was a man born for war. He trained his whole life, studying the tactics and strategy of military commanders long dead. He didn’t just learn it; he applied it. In this way, he was able to take into account the accumulated strategic wisdom of all of human history when he made command decisions.
Patton seemingly itched for war, wanted nothing more than to participate in great battles. Convinced that he had died gloriously in ancient wars, he had no qualms about dying heroically in the name of American conquest. Probably his greatest frustration was that World War II ended. Some of his comments indicate that he wanted to keep going at the end of the war, attacking the Soviets after German surrender.
In other words, Patton was an unstoppable killing machine.
Whatever else you might say about him, that is precisely the sort of man I would want in command of my military during wartime.
