Great minds think alike or led by the nose?

Update to the last post – surprise! There it is in the book, I found today. Kennedy was afraid of the monster he’d created in NASA and, given the opportunity, he’d have done a deal with Krushchyov to end the space race. So did the military/industrial Mafia behind NASA realize that Kennedy was more valuable to them dead rather than alive and wobbling, and have him whacked?
