The main part was Kennedy wanted to end production of nuclear weapons and wanted no more countries obtaining them. The Rosenbergs were executed 10 years earlier for giving info to the Soviets and at the time nuclear weapons were a major political issue. Kennedy was actively trying to get the Soviets to abandon nukes and he wanted the US to do the same. Kennedy probably didn't realize the jew fuck bastards that ran the Soviet Union had no intention of doing that. I am damn sure the info passed to the Russians was also passed to Israel. The jew fuck bastards in Israel wanted Kennedy out of the way and Kennedy spent an entire life gathering enemies from all walks of life. The plot to kill him was literally genius. Everyone gained from the main dying so who really did it? My guess is naval intelligence, the CIA, and Mossad were the planners and provided the bankroll. The rest was recruiting and carrying it out.
