JFK’s assassination occurred against the backdrop of tensions between the USA, Cuba, and Russia. Oswald was a known Cuba-Russian sympathizer, and according to Perry, this is the hardest theory to debunk.

“Supposedly Kennedy was fed up with the shenanigans that the CIA was pulling,” he told CNN. “He found out the CIA was trying to kill [Cuban leader Fidel] Castro, which is a fact. So the argument is that the CIA felt that Kennedy was going to disband them. And as a result of that, they were the ones that ordered the killing of Kennedy.”
