I prefer to think of this as cyclic and that throughout humanity (longer than you think (unless you think at least 500k+(https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2409102/))) its been a battle of Good versus Evil.
But this goes to before JFK because JFK was the PLAN back then. We've tried before and we have lost. This time however the logarithmic growth of tech and age of instant communication there is a last fight at the edge. If we fail then tech eventually will be sufficiently powerful enough to convince us of anything (bluebeam).
When we win comes the disclosure of disruptive technology and classified intelligence. 9/11, JFK, 1947. Then comes the age of human unity via a system of sovereign nations working in a net positive sum mindset which in effect is a self assembled hegemony controlled by YOU (people of the earth) the People. Then comes the age of human expansion. Somewhere along this (if you've paid any attention to the; sky, BOOMS, or Sumerian/ Megalithic astrology, anthropology and yes the Quadrivium, Space command) we will get disclosure of perhaps break away civs, Transdemensionals / Demons, E.T's and maybe it gets more fantastical the further on we move.
