The idea that they do is a claim that comes up very often with the Far Right (the real Far Right, not the SJWs’ “you don’t want men in women’s locker rooms so you must be a fascist” version of the Far Right) when i point out that even though Jews are grossly over-represented in the West’s power structures they are still a minority and therefore not in control. It also comes up a lot when Americans try to explain why Israel supposedly controls America — “sure, we have the money and the weapons but they have photos of Donald Trump fucking a duck!” So goes the argument.
The problem with this is that it assumes that only the powerful Jews are out there digging up dirt on the opposition. How likely is this? So unlikely as to be impossible. The gentile oligarchs are just as smart and amoral as their Jewish counterparts, so it goes without saying that they are gathering dirt with which they hope to blackmail the Jews. The only other possibility is that the Jews are such good and pure people that there is no dirt to get on them. Needless to say, that’s not only offensively anti-gentile but also laughable given what’s happening in Gaza right now. So it’s a very safe assumption that while Soros has dirt on Musk, Musk has dirt on Soros, and that while the Mossad has dirt on everyone in the congress, the CIA has dirt on everyone in the Knesset. This, of course, leads to a stalemate where it is usually impossible to blackmail people on the other side of the fence. There will be cases where one side has a peccadillo, like duck-fucking, while the other side has a major crime, like serial rape, but usually it’s peccadillo vs. peccadillo and that means nobody has an advantage. In other words, while the Mossad may have photos of Donald Trump fucking a duck, you can bet that the CIA has photos of Netanyahu fucking a chicken!
