Ummmmm. I just looked this up. This appears to be the latest re-hash of a conspiracy theory over 100 years old that contends that the Rothschild family, and Jews generally, secretly rule the world by pulling strings from behind the scenes. A certain PhD kept coming up when I searched for “Khazarian Mafia.” Dr Preston James, PhD. He claims that Israel did the 9-11 bombings. This is just nuts.
Its simply not reality, and has led down a path towards some terrible outcomes in Russia, Central Europe, and elsewhere.
Aside from your belief in this “Khazarian Mafia”, you seem like an otherwise smart and good guy. It’s often hard to tell what’s what with all the diverse and divergent information all around us. I would encourage you to investigate the folks propagating these ideas and re-examine your belief in this rather far-fetched theory.
