What if during a Nazi victory the Nazis begin to attack amd exterminate the Middle East since they are Semitic. Using the map from Phillip K. Dicks "Man in the High Castle" lets assume the Slavic people, Jews, amd other who were able to escape extermination were able to resettle in parts of Siberia and Kazahkstan. In this timeline the Muslims who were not exterminated also go to these areas. There a young man of Jewish descent listened to a Rabbi and went and prayed, he had a vision and began to preach unity between Jews and Muslims. Slowly there are followers who soon joined this fringe group. Boris Belikov received a vision that the sons of Noah needed to unite and become one in worship. Imams and rabbis soon distanced themselves from this charismatic leader but he became a pillar of the community. He opened soup kitchens, clothing recycling for widows, orphans, and the invalids. The Religion known as Sons Of Noah became small but powerful. Boris taught that Islam and Judaism are the same because Muhammad was a relative of Noah thus proving his prophethood amd converting Jews and Muslims in record numbers. The Sons of Noah celebrated the Jewish and Muslim holidays, reincorporating Polygamy into Judaism and keeping with Islam but the major difference was that Belikov preached that cousin marriage was not okay according to the laws of the Semitic people's. The major languages of Hebrew, Arabic, Russian, Ukrainian and many others became common in Siberia and Kazakhstan. The Sons of Noah became known not as Jews or Muslims but referred to themselves as Semites. The Jews and Muslims became a group the Nazis soon hated. Many formed militias, Muslims having fought the British and later Germans while the Jews were familiar in combat from their battles in Stalingrad the Jewish uprising and other conflicts.
