I guess both sides could have done things smarter or dumber. BUT, even if Hitler had been a bit more smarter than he was I dont think it still would have mattered. It probably would have cost more in lives, but I believe Hitler would still have lost the war. If there was one lesson learned throughout history, DONT ATTACK THE RUSSIANS. Fighting them man on man is the dumbest thing you can do. Under communisim they may still have been the less motivated people, but the minute you step on her toes there are enough people, with the tencity to fight on even if they are dead (cuz no one told THEM yet :-D ). Of course Hitler brought the Russia problem on himself. As for America? Well, as I said, it may ahve cost more in lives, but FDR was ready to take back Britain from the Germans had they succeeded in that respect.
Bottom line, its good things didnt get too out of hand or Berlin would be glowing gree in the dark along with those two cities in Japan......
