Stalin’s antisemitism is a myth. Antisemitism was punishable by death and there still were plenty of Jews present in the party. Shortly after the second world war the Jewish Autonomous Oblast was formed in the USSR to provide a safe haven for Jews.
Stalin was anti Nazi even before Hitler took power.
