Thanks to diligent reporting from two independent outlets, Drop Site and Reason, we now have a much better sense of Epstein’s relationship with the foreign policy elite of the US and Israel. It seems that Epstein was not a CIA or Mossad asset—not because he didn’t have it in him, but because that was too lowly a role. Rather, he was a power broker, an American oligarch, who played a major role in shaping Western policy, which brought him in contact with spy agencies and diplomats.
It's a pretty interesting claim that Epstein was too big to be a spy. This article references two main other articles to support this idea. That makes it seem strange to me that he got caught at all.
