And note the SS death’s head insignia on the cap (under the Nazi eagle, for those in Rio Linda), heh...
Those were Bosnian Muslims of an SS regiment raised by the Grand Mufti of Jerusalem, Haj Amin al-Husseini. Their sole mission was to hunt down and kill Jews.
They are reading something entitled “Islam and Jewry”, no doubt excerpts from Mein Kampf where Hitler praises Islam as a superior religion for a master race.
Ironically, Hitler despised Arabs; when Haj Amin journeyed to Berlin to offer his services, Hitler refused to meet with him until his adjutant whispered, “Mein Fuhrer, the Mufti has blue eyes”.
“Send him in”, was Hitler’s reply.
