Patton also believed he had been reincarnated as a warrior many times throughout history:
General George S. Patton - died December 21, 1945
General David Petraeus - born November 7, 1952
Well...?
It would be difficult to find two such consummate warriors as Patton and Petraeus who differ more in personality.
Patton would never have been able to handle the counter-insurgency warfare in Iraq. What it required from a commander was totally alien to his style of warfare.
OTOH, I suspect Petraeus would have done just fine against the Wehrmacht. (Especially if we allow him a few dozen Abrams.)
