you're talking about the WWII contest specifically, though. I'm referring to a Cold War afterwards, when Stalin is long gone. The Nazis will be limited in looking for allies by their racial supremacy beliefs.
The Nazi's were allied with Spain (Franco), so that opens up all of Latin America as possible allies (join the winning team). They also had Japan, so there's another, fairly large group.The United States had a Nazi party before the war, although Hitler apparently didn't get along with it's leader. I'm not sure if Canada had it own Nazi party, perhaps under a different name?
There was also a connection with certain Arab groups, don't know if that rose to "allied" status. The modern middle eastern Batha party is basically the Nazis under a different name.
So the Nordic/Aryan Nazis would/might have been at the top of the pecking order, but there was plenty of room for others.
