I’m surprised no one has mentioned it but especially after seeing the files I think it was very likely Zionist Israel and Mossad. Gaddafi said the same before he was unalived.
The real giveaway is Jack Ruby and the horseshit excuse the media gave for him. The Israeli mafia member killed Lee Harvey Oswald while the media floated it was “because Jack really loved JFK”. So the guy who loved JFK so much that he killed for him, was in Dallas the day JFK was there and didn’t even attend the event…Sure.
JFK didn’t want Israel having nukes and decided to inspect a nuclear plant over there. I think the federal reserve and CIA enemies didn’t help either. LBJ takes over and all those of things went back to status quo, Israel got their nukes. Happily ever after.
