My history isn't great but I've always wondered this question ever since learning about JFK's assassination happening only three weeks after Diem's assassination during a coup which JFK actually knew about. Considering how little we know of JFK's assassination would it be completely implausible to say that the two were somehow linked? I haven't been able to find anyone else online suggesting this although I'm not the best at finding things on Google. I know I must be missing something and my idea is probably complete bollocks so I'd appreciate a respectful answer considering I'm not particularly knowledgeable of history and am still learning it at school but I am very interested in it, particularly this area of history has always intrigued me.
To clarify, I believe I remember learning that JFK whilst supposedly not having any direct organisation with the coup against Diem, did know about it beforehand and allowed it to happen as Diem had lost US support. Then, only three weeks later he himself was assassinated famously. I've always wondered if perhaps the assassination was some sort of revenge against his knowing of the coup? Again, I am almost certain I'm going wrong somewhere but I'd appreciate someone pointing it out to me.
