If there was no speech at Columbia University it appears this quote is a fabrication. Liberty-Quote should send an email retraction to avoid expanding conspiracy stuff regarding JFK. There is already enough of that extant thanks to the Stone's JFK movie. I happen to believe JFK was killed by the CIA because of the Bay of Pigs and his lack of enthusiasm for the Vietnam War, willingness to fund Eisenhower's military industrial complex, but the facts are important and this quote is not sufficiently certain to be circulated.
