Nonsense. Hitler had contempt for Blacks and Slavs. But he didn’t view them as a threat in the same way he saw the Jews as a threat. And to say that he admired what Islam enabled the Arabs to achieve militarily isn’t to say that he thought Arabs and other “non-Aryans” were his equals.
Not as much as the Jew. He still viewd blacks and Slavs as useful. He didn’t think Jews were useful at all.
