It seems to be all about money and banking. How about George Soros - he's got the money to afford this and more.
Given his background and the particular method by which he made his pile, he could very easily be associated with Russian oligarchs and involved in some way. Again, the oligarchs have a large overlap with both the Russian gangs and government. But I don't think Soros would be directly behind it, beyond identifying people to extort, coerce, and/or take out to those who are really running the show. Of course it is in the nature of a guy like Soros to
think he is playing the silent partners, right up until they find him either a liability or just no longer useful, when he will suddenly find out who's
really being played, as his personal lights go out.
