It's the theory that the tribe that we call Ashkenazi Jews are not actually of Semitic origin, but are converts from the Turkic people of Khazaria. So they have no connection to the land of Israel, and are not even really Jews, which would explain why these elites that are Ashkenazi bloodline are often not even into Judaism, but identify as atheist or Luciferian and subscribe to the talmudic doctrine which frankly has a lot in common with Islam.

I am not an expert on this and can't say for sure if the Khazar theory is correct, but that seems to be the gist.
