Was John F. Kennedy in danger because of his speech in November of 1963?

I don't remember that speech, but I was only 15 at the time. Still, this isn't the first I've heard of Bush Crime Family involvement in the inations of JFK and RFK, the character ination of Ted Kennedy, the ination of JWOL and attempted assassination of RWR, both by readers of "Catcher in the Rye" (one of them the brother of a friend of Neil Bush), or the death of JFK, Jr. It's like there's no room in this town for a benevolent dynasty when an evil one wants power.
