Quite likely that the more daring Patton could have prevented the partition of Germany, or at least left a smaller E Germany.
Especially if Ditka was driving.
Probably not. The partition of Germany had been settled at Yalta the year before.
In another “brilliant” move, Ike would not let Patton take Berlin and gave it to Stalin. I know that it saved American lives by allowing the Soviets to take Berlin. However, the Germans would have not have put up as brutal a fight and would have surrendered much easier to the Americans than the Soviets. This also helped to ensure Soviet dominance in East Germany for the 40+ years.
