JFK was killed because he had an attack of conscience and went against the will of his masters, not due to some fanciful left, right charade.

That day already cold early morning deep in Russian province my young scared mother run to my bed: Sonny, wake up. Kennedy killed. Couple years before our military shot spy plane, space race just started... But they recently exchanged good wills over Caribbean crisis. We all were terrified, trained to hide in nearest bomb shelter. Cold war and insane arm race were under way. That's the cost to brainless rhetoric and rampaging evil in society.
