I doubt that Ghislaine Maxwell and Epstein were working for Israel’s intelligence agency. I think Epstein figured out there were a lot of rich people and powerful people who were into paedafilia and he found a way to offer it to those nasty people.
In turn they let him in on a lot of lucrative deals and he got very rich. His clients figured out he had incriminating videos so they made it clear if he ever was in a position when or where those videos could be leaked, he would die. Thus his “suicide” in jail. Ghislaine knows this too so she will keep her mouth shut, no matter what.
The hole in all these theories is that Epstein as clever as he was - and he was, especially if these theories are correct - should have had systems in place to expose them if he got suicided.
Of course he would have had these systems in place. Plural. In case one or more failed.
Since no huge spill of information has come out, he obviously didn’t have them. Which makes me disbelieve he was a world class blackmailer.
