operation barbarossa was a mistake, he tried to sucker punch Russia and he missed. When you try to sucker punch and you miss, you are fucked.

His panzer doctrine ("the bigger the better") was faulty. German tanks were too heavy and hard to repair. Wehrmacht lacked adaptability.

Sunk cost falacy, Hitler couldn't admit he lost a battle and retreat (Stalingrad) so he lost the war instead.
