I remember hearing somewhere that after an attempt on his life by far right elements of the French version of the CIA, de Gaulle sent a wire to JFK warning him that the same could happen to him. JFK responded something like, "lol for that to happen here, you'd have to have a young president who had some kind of a Bay of Pigs situation oh no haha." I have no memory of where I heard that and I'm posting at work so I don't have time to go hunting all over, but when I heard that, it definitely confirmed my suspicion that the CIA had something to do with it.
