Hitler, as we all know, was famous for refusing to admit any more Muslim immigrants to Germany.
Stands to reason that if Hitler was being urged by mudslimes to retain Jews in Germany (for extermination) rather than emigration to what would become Israel, those same mudslime advisors would urge Hitler to not take mudslimes so as to leave more eligible mudslime fighters in the middle east.
Hitler wished that Germany was Muslim. Christianity was a religion for weaklings, according to Hitler. Islam was more suited for soldiers.
