Input: Consider Input: Question: When was the author of JFK and the Unspeakable born? Passage:Jim Garrison said anti-Communist and anti-Castro extremists in the CIA plotted the assassination of Kennedy to maintain tension with the Soviet Union and Cuba, and to prevent a United States withdrawal from Vietnam. James Douglass wrote in JFK and the Unspeakable that the CIA, acting upon the orders of conspirators with the "military industrial complex", killed Kennedy and in the process set up Lee Harvey Oswald as a patsy. Like Garrison, Douglass stated that Kennedy was killed because he was turning away from the Cold War and pursuing paths of nuclear disarmament, rapprochement with Fidel Castro, and withdrawal from the war in Vietnam. Mark Lane author of Rush to Judgment and Plausible Denial and the attorney who defended Liberty Lobby against a defamation suit brought by former CIA agent E. Howard Hunt has been described as a leading proponent of the theory that the CIA was responsible for the assassination of Kennedy. Others who believe the CIA was involved include authors Anthony Summers and John M. Newman.
