We won a war against them, so they are already by definition losers.
But that is not all. They were all like “We have the best people, nobody is as strong, intelligent, handsome, … as us. Our army is the best in the world, most high-tech, best supplied, …”
Then they fought a single war and lost.
Not only that, they lost against a coalition of many different countries that allowed anyone to join.
So the Nazis were literally defeated by diversity and inclusivity.
