You re missing the point there is a theory that Ashkenazi Jews originated in Khazaria not Israel and converted to Judaism only in the 8th 9th Centures C E The western portion of Khazakhstan corresponds to historical Khazaria so it s almost like Sacha Cohen half Ashkenzai Jew is poking fun at the people from the same region where Ashkenazi Jews are proposed to have originated from and to make matters even more funny Borat is anti Semitic Face it if Borat grew a beard and had a NY accent he d be Jewish all the way because Sacha Cohen looks like a Caucasianized Eastern European Jew even though he has a Sephardic mother
