I can’t see who killed JFK, but I might be able to forward a plausible theory about why it was felt necessary to kill him.
JFK was in terrible health, and one of his worst afflictions was Addison’s disease, which today is closely associated with him. With the severity he had it, a major and unique symptom is the appearance of the skin of the upper chest and face. If you are looking for it, you can even see it on him in the pictures and film of the time. At the time, any physician familiar with Addison’s would have known he had it at 50 feet, just by looking at him.
The only effective treatment they had for years for Addison’s was cortisone, which was very expensive and rare. For this reason he had supplies of it and other essential drugs stored in safe deposit boxes around the US.
But then, in the early 1950s, a pharmaceutical company developed a process to make artificial cortisone cheaply. As a very useful drug, it was soon seen as a “miracle drug” and was widely prescribed for many conditions.
However, the false rumor began in the medical community that taking too much cortisone could make a person mentally imbalanced, even clinically paranoid. This became amplified terribly with the release of the James Mason film Bigger Than Life in 1956. Mason did a “chilling” performance of a mild mannered man driven into a homicidal rage by taking cortisone.
So far, just about anyone could piece together that the president had Addison’s disease and was taking cortisone, which could drive him mad.
But then the Cuban Missile Crisis happened. Suddenly the light dawned that the president could become insane, *and* that he had his hand on “the nuclear trigger”.
JFK was asked by many people to step down for health reasons, but he always adamantly refused. So isn’t it reasonable to assume that *someone* decided that he was too dangerous to live?
When Kennedy signed Executive Order 11110 which called for a return of America’s currency to the gold standard, and the dismantling of the Federal Reserve System — he signed his own death warrant.
The world bankers were not going to allow some foolish rich kid to crush their power machine.
