Every indicator is that a cataclysmic, tidal-shift in liberal social-politics took place, on a global scale, almost immediately after the murder of President Kennedy, that almost exclusively favored the extreme fascist elements of humanity.
It was, in my opinion, a military coup, that involved domestic & international elements, state & non-state actors, with ranks of personnel in the hundreds, completely non-aligned from any structural organization, but instead were representational of personal social networks.
And it was highly compartmentalized.
