Hitler certainly used Middle Eastern antisemitism and allied with the Arab Nationalists, Muslim Brotherhood, and the Arab leaders in British Mandate Palestine to slaughter every Jew in the region. But this was far from the genesisi of antisemitism in the region. It goes back to Jews refusing to convert under the Hellenistic Syrians and then Romans. Islam created its own antisemitism. Medina was once called Yathrib and dominated by Jews. After Mohammed and his cult fled Mecca, they were given shelter in Yathrib, largely because many members of his clan were Jewish. When enough people converted to Islam, Mohammed waged war on the Pagans, Christians and Jews of Yathrib. Mohammed had a tummy ache, claimed he was poisoned, and proceeded to have every adult male member of a clan of Jews killed, took their wives as rape slaves, and their children for all purposes. Mohammed famously raped Rayhana bint Zayd while literally covered with her husbands blood.
Thanks for getting the history right. I think Hitler exploited the preexisting antisemitism through his propaganda program on steroids. The plan was to use antisemitism to wrestle control from England of the oil resources in the Middle East and control of the Suez Canal. That effort has come to haunt us today even though we took out the Third Reich.
