To say that Patton does not stand up aginst a commie general-Zhokov - is one of the dumbest statements I have seen in a long while. I think you need to go back to the post office.
By all accounts he was more a military man than anything else.
One of the worst things you can do is let ideology blind you. Just be thankful Zhukof was on "our side" and not Hitler's.
You might well ask why it was Patton was not selected as Supreme Allied Commander. That will give you some answers to why any rational analysis has to place Zhukov head and shoulders over Patton.
