Well...that's not entirely accurate.
You may recall they were quite tolerant of the Japanese who were not well known for being tall, blue-eyed blonds; Arabs and Persians were also acceptable.
In other words, the Nazis were more like democrats, tolerant only of those of like mindset (as long as they weren't conserv... I mean, Jewish).
Same game, different players. Same intended result (as soon as they disarm us, that is).
They tolerated them because at the time they needed them; the Arabs and Persians in the Egyptian and Balkan campaigns and the Japanese in the Pacific to keep American, British and Dutch troops occupied and out of Europe. If they had won the war I am pretty sure that they would have got around to eventually exterminating them.
