That hardly proves anything one way or the other.
The fact remains that a week before that day, the US was in the process of withdrawing from Vietnam, and a week later under different leadership began the process of escalation, thus changing history IMO not for the better.
Well, you got me there.
It really is inconceivable that a communist, with USMC rifle marksmanship training, who defected to Russia for a while, might get bent out of shape by the most outspoken anti-communist POTUS since before WW2 and have the ability to shoot him.
Nah, it had to be a conspiracy.
