well the West's current zeitgeist is a direct backlash to the Nazis and WW2. The Nazis made European nationalism unpalatable. They also made White ethnocentrism taboo. Europe decided to reject its prior obsession with race and homogeneity, and chose to open up its societies (without ever imagining the damaging consequences of mass immigration and multiculturalism, because European leaders are functional retards). Not to mention that WW2 left Europe with a labor shortage, and so Muslims were imported to make up for this.

As for Germany specifically, the Nazis brought upon their people the destruction of many of their cities, the death of millions of young men, the rape of their women, and then 45 years of Allied/Soviet occupation. The Germans were forced by Americans to allow the migration of Turks as a source of cheap labor. And their guilt has led them to a state of total cuckoldry, to the extent that they have imported millions of nonWhites. There hardly even exists a cultural Germany anymore. None of this would have ever, ever happened without the Nazi's loss.

So it was a large gamble. Beat the Russians and the Nazis would have given Germany possibly the greatest nation in world history. But lose, and the Germans would become dispossessed.
