I never criticized Hitler for not being Pan-European; I criticized him for placing the Arabs (non-whites) above Europeans.

From Albert Speer's memoir -- which, again, is a dubious source, self serving and should be taken with skepticism but let's just assume it's true.

Hitler said that the conquering Arabs, because of their racial inferiority, would in the long run have been unable to contend with the harsher climate of the country. They could not have kept down the more vigorous natives, so that ultimately not Arabs but Islamized Germans could have stood at the head of this Mohammedan Empire.
