Question: How could the American electorate be so ignorant as to elect Donald Trump in 2016 and 2024?
Answer: It was the result of the cumulative effects of fifty-plus years of KGB disinformation and "active measures" operations aimed at getting Americans to distrust their government.
For example, Oliver Stone's 1991 film, "JFK," the origins of which can be traced back to an anti-Clay Shaw / anti-CIA article published in a Communist-owned Italian newspaper, Paese Sera, three days after overly ambitious, scandal-plagued, and revengeful New Orleans DA Jim Garrison arrested Shaw on suspicion of having masterminded a homosexual thrill-kill assassination of JFK, and which article motivated Garrison to change his theory against Shaw to "He organized it for the evil, evil CIA."
