"I mean sure, it was about race, not about passport. "

But we agree it seems. I was just arguing against the common missconception of trying to understand the Nazis as Ultra-nationalists, while they were mainly thinking in racial terms. Not germany should have ruled the world, but the Aryans. (With germany at it's heart, but that was more a side point)
