The real difference between Stalin and Hitler...
Everyone loves a winner, no one likes a loser.
Zhukov.
Stalin was one lucky Сукин сын since, when he killed off all of his good officers in the 1937 purge, Zhukov somehow survived.
Hitler would have won Operation Barbarossa if he had actually stuck to the original plan, went straight to Moscow with his main force and swooped south to take over the oil fields, but he couldn't help himself and sent half his troops to Stalingrad instead. If Adolf had listened to his generals, it would never have happened.
