In the words of author James W. Douglass, this was President Kennedy's greatest speech. His unprecedented turn toward peace in the wake of the Cuban Missile Crisis was seen by the National Security State as treasonous. Shortly thereafter his own NSS brutally murdered him.
I wholeheartedly recommend Douglass' book JFK and the Unspeakable: Why He Died and Why it Matters, 2008, and the 5 volume tome by Douglas Horne, Inside the Assassination Records Review Board: The U.S. Government's Final Attempt to Reconcile the Conflicting Medical Evidence in the Assassination of JFK, 2009 available HERE... who in excruciating detail documents the medical cover-up.
