Hitler allied himself with groups that he despised ideologically, including Muslims and the Japanese. If he had managed to have world dominion then the persecution of those groups would have followed after the eradication of the groups he mainly focused on. Even Norwegians would have been seen as somewhat lesser humans than "true Germans" unless they had been sufficiently integrated into German Nazi culture, language and ideology to pass as Germans. I know this because Norway was occupied by the Germans from 1940-1945. We were sort of seen as Aryans but not quite.
Both extremes typically hate the nation of Israel and religious Jews, which is a spiritual phenomenon as you suggest. Some extreme right wingers do however embrace Christian values sufficiently to tip over into seeing Islam as their main enemy and they may actually find themselves on the pro-Israel side, not because of a love for Jews or Israel but as a function of their anti-Muslim sentiments.
There's a lot of cardboard Christianity among European far right wingers, with professions that sound Christian and hearts that are full of hatred.
