In our "Truther" community, people often talk about the "Khazars" or, thanks to the coining of the term by Ben Fulford, the "Khazarian Mafia", or "KM".
Prior to that, there was talk of the Khazars by the well-known independent filmmakers Janet Ossebaard and Cynthia Koeter, who spoke about the Khazars in their popular, multi-part documentaries "The Fall of the Cabal" and "Sequel to the Fall of the Cabal".
Prior to that, the torchbearer of the idea of "Khazaria" was drawn out by Arthur Koestler, in his well-known book "The Thirteenth Tribe".
As Khazaria is contained to a large extend by present-day Ukraine and a small part of southern Russia (the territories are historically contested), older and more accurate history of what took place in Khazaria may well reside today in Russia.
I believe Russia will have, in its upcoming contributions to Disclosure (what they uncovered in Ukraine and ancient history - note they also have the ancient territory that was Tartaria in present-day Siberia) some pretty daming information, about "who ran the world" until recently.
It is nice to feel justified and safe to use that term in its past tense now.
