All the Presidential Conspiracies

Who killed JFK? Commentary's Jacob Cohen has a run down of all those who have been bruited to be behind the murder:

It was anti-Castro elements, furious at Kennedy for his betrayal during the Bay of Pigs invasion and his failure to dispatch Castro during the Bay of Pigs crisis. It was pro-Castro forces, furious at Kennedy’s attempts to assassinate Castro, also alerted by Kennedy’s sudden turn to a strongly anti-Communist position during the campaign, a turn that resulted in his contested victory over Nixon in the 1960 election. It was Nixon, angry about the outcome and also fearful that Kennedy was preparing to lead the United States out of Vietnam. Nixon’s connections with organized crime, derived from his involvement with illegal drug rings, also led him to think ill of the president, which naturally means to think of killing him. Suspiciously, Nixon was in Dallas the night before the assassination and departed just after or before the assassination, or perhaps he did not depart...

It was the Soviets,⁵ who, having programmed and trained Oswald to assassinate Kennedy, may have changed their minds and tried to deprogram him during his visit to Mexico City in early October 1963. It was the KKK, a former member of which foretold that Kennedy would be assassinated in Miami. It was, of course, organized crime, which hated Kennedy’s brother Bobby, their nemesis, and whose drug and gambling interests were being threatened by either Castro or Batista, and therefore by Kennedy, who swung all ways on these matters as well. Organized crime then ordered Ruby to kill Oswald, a kind of suicide bombing to which Ruby agreed because he favored a slow death in prison to the torture he would have received had he defied orders. It was the CIA, which actually had engineered previous assassinations, most notably of Jacobo Arbenz in Guatemala in 1954. The Arbenz assassination set the stage for their unsuccessful Bay of Pigs invasion, which in turn prompted anti-Castro Cubans to hate Kennedy and, therefore, proves that the CIA was the cause of the Kennedy assassination. It was Lyndon B. Johnson, for obvious, Macbethean reasons, but also because he hated the Kennedys, who constantly humiliated him—and because he, too, opposed Kennedy’s intent to leave Vietnam. Did you know that Johnson’s long-time mistress claimed that Johnson whispered to her (at a party they attended in Dallas the night before the assassination), “After tomorrow, goddamn Kennedy will never embarrass me again”?... 

It was the Justice Department. It was the Watergate burglars and especially Howard Hunt (punished for his illicit knowledge by the assassination of his wife). It was the same people who organized at least three other assassination plots against Kennedy, each similar to the Dallas assassination, with a patsy who was an ex-Marine looking “remarkably” like Oswald and an attack plan replicating the events in Dealey Plaza. It was China. It was jealous husbands whose wives consorted with JFK. It was the Dallas police. It was Washington insiders like the legendary James Jesus Angleton (who knew all about Oswald well before the assassination), and Allen Dulles. It was the French drug mafia, which was allied to the South Vietnamese drug mafia. It was the Corsicans, those notorious assassins, one of whom, world renowned, was in Dallas on the day of the assassination and was never even detained and questioned! Have I mentioned the Military-Industrial Complex?... 

Oswald, though, did not do it, although he was involved and would need to be framed as the designated patsy. After all, there is “credible evidence” that Oswald worked for the KGB, but also Naval Intelligence and the CIA. He was, therefore, simultaneously, a single, double, and triple agent...

 It was da Joooos!
