Look, it's all bunk. I don't even have to read one book on Khazars to tell that it is typical judeo-baloney. But this web site lays it all out - and see his conclusions. No evidence that Jews are anything special. They are the same as Palestinian Arabs. Even the Cohen gene is nothing special. It's all bullshit, which is all you can expect from these incredible liars.
