I disagree.
JFK was murdered by a rogue Communist by the name of Lee Harvey Oswald.
The conspiracy theories around the JFK assassination were started by the American Left to hide the facts of the case, and to make a martyr out of a Leftist president with a track record of failure two years into his term of office.
Otherwise, why would Oliver Stone expend so much time, energy and money to make a movie that twists the JFK assassination every which way in order to indict the “fascists”, i.e, the Patriots, as being the real assassins?
I'll let the facts stand in the face of the gooberment “answer” to the question at hand.
