>>510089332 (OP)A German saying goes: "Even a blind rooster is going to eventually pick up the corn." (German equivalent to ,,even a broken clock is right twice a day"). Guess it also works vice versa, even a healthy Rooster might miss one. The Nazi ideology made one wrong assumption: That the western Powers of Britain, France and America were equal to the Aryan Race while the East was inferior.
What actually transpired was the opposite. The French, despite maintaining the strongest land army at their time got steamrolled, the Brits ran back to their island with the tail between their legs and only beat the undersupplied German token force in Africa with certain difficulties, the Americans struggled against a small portion of a heavily battered German war machine (while the majority was deployed or dead on the Eastern Front) despite theoretically outcompeting the Germans in every single metric (Industry, technology, Numbers, Vehicles, air superiority,...). Meanwhile the Sovietss, altough backed up by Lend-lease, managed to stop the Nazi War Machine and offer a fight that has yet to be surpassed in scale in the entire Human history. The Slavic resistances brought the Germans much more difficulties than the Western Resistances and most Germans rather surrendered than facing the Soviets.
Hitler himself admitted it in the end that the East proved itself to be worthy of an opponent.
