While they hated the Arabs as a “race,” (whom Hitler called monkeys, even when he met the Mufti in 1941, he refused to shake his hands) they admired the totalitarianism of Islam
On the other hand, Persia became “Iran” in 1935, because the then-Shah was such an admirer of Hitler, he changed it to the Farsi word for “Aryan.”
I imagine Hitler’s plan was to inevitably coax the Turks into creating a new “Ottoman Empire” to rule over the Arabs, and keep them in line.
