The KGB from decades ago helped Trump get elected? LOL. That may be the single dumbest JFK-related conspiracy theory in history and most tortured example of Trump Derangement Syndrome that has ever been contrived. Which is saying a lot. A whole lot. No one needs to "encourage" the citizens of the US to be skeptical of our government. The US government provides ample grounds for doing so. Vietnam, weapons of mass destruction, Afghanistan, Ukraine, COVID, open borders, no pardon for Hunter, Biden is fine behind "closed doors" and on and on. I say "no."

By the way, didn't you know that during the January-February 1959 Extraordinary (i.e., mid-term) 21st Congress of the Communist Party of the Soviet Union in Moscow, the Kremlin, having realized that the USSR and the Warsaw Pact couldn't defeat the US and NATO militarily, decided to try to get us to tear ourselves apart by waging long-term Sun Tzu-like deception, "active measures," and "Inside Man" / "Outside Man" strategic deception counterintelligence ops against us and our NATO allies?
Don't you think the KGB's publishing an anti-Clay Shaw / anti-CIA article in a Communist-owned Italian newspaper (Paese Sera) three days after Jim Garrison had arrested Shaw on suspicion of having organized a "homosexual thrill-kill" assassination of JFK, which article -- given to Garrison by Bertrand Russell's London secretary / Joan Mellen's ex-husband, Ralph Schoenman -- probably motivated overly ambitious, scandal-plagued and revengeful Garrison to change his theory against Shaw to "He Organized it for the Evil, Evil CIA!!!" falls into the category of disinformation / "active measures"?
You do realize, don't you, that Oliver Stone's movie "JFK" was based largely on Garrison's specious 1988 book, "On the Trail of the Assassins," and that it led to something like 70% of Americans' believing the JFKA was a CIA conspiracy, which in turn contributed to the making cynical and paranoiac a good part of our body politic? Which cynicism and paranoia, with help from the likes of Alex Jones, QAnon (Michael Flynn?), and Putin's professional trolls in St. Petersburg, et al. ad nauseam, The Traitorous Orange Turd (who was compromised by the KGB by at least 1987) was able to take advantage of during the 2016 and 2020 campaigns and get hisself (sic) "elected."
