Dulles brothers are at the root of it all. Allen transformed the OSS into the CIA and later was the chairman of the Warren Commission that blamed a lone shooter for the assassination of JFK.
The Dulles brothers came from Southern oil Money and were very close to the Bush family. GHW Bush, who eventually became CIA director himself really worked from the CIA from the moment he graduated college and Skull and Bones.
It was Allen who was friends with LBJ and Hoover.
Many revisionist historians think the JFK assassination was about southern oil interests and the military intelligence complex taking out JFK because he had been converted into a dove and planned to end the war in Vietnam.
The Dulles brothers and what they created in the early 60s is what executed 9/11.
This is why the JFK assassination is still so relevant, today.
But, I'm sure most that are here know this already.
Here is an outstanding interview with David Talbot who recently published "The Devil's Chessboard, Allan Dulles, and the Rise of America's Secret Government."
