Shower thought:
JFK, Reagan and Trump were all struggling against the cabal. JFK made his intentions clear to the public and he paid the ultimate price. Reading between the lines; Reagan hinted at what was going on and the future consequences of not correcting our course.
Growing up during that era, there was a lot of news about Reagan's Strategic Defense Initiative or "Star Wars" program. The plan was to have armed US satellites orbiting earth ready to obliterate any inbound nukes (or anyone) that dared attack us. I assume that the project was already well underway when he announced it on March 23, 1983.
"I call upon the scientific community in this country, those who gave us nuclear weapons, to turn their great talents to the cause of mankind and world peace, to give us the means of rendering these nuclear weapons impotent and obsolete"
The Space Shuttle was a VERY popular NASA success at the same time and the payloads were occasionally "classified" since nearly every launch was a big deal and televised.
Since we sorta know how the cabal operates, it's possible that they knew of "Star Wars" in addition to Reagan's other plans and had him shot, and maybe even had someone sabotage the Space Shuttle Challenger. Doing so would derail the means to install a weapon system so advanced (for the era) that the any faction of the cabal could be evaporated at any moment.
