Rob,
What did the Kremlin gain by assassinating JFK?
You mean other than the deleterious effects the hordes of Mark Lane and Oliver Stone, et al.-inspired CTers have had on our country over the years through their unwitting spreading of what boils down to anti-CIA, anti-FBI, anti-Military, and anti-Federal government Ruskie propaganda for fifty years now, all of which unfortunately prepared the way for KGB-boy Putin and his lackey-agent Assange to install, through yet another "active measures" campaign, Russian Mafia mobbed-up, "useful idiot" Donald Trump as our president?
Or do you mean the things Mark Riebling writes about in his 1994 book, "Wedge"?
If the latter, then why don't you just read the two pages of that book that I suggested to you?
LOL
