I totally disagree.
The Cuban Missle Crissis, the Bay of Pigs, an AG's war against organized crime all done by a moderate president belonging to a party the Soviets were trying to infiltrate.
That kind of president and that kind of Democrat was not in the interest of the Soviets.
And the effect on the Democrat party was chilling. Democrats from that point forward started acting in support of anti American and pro Soviet interests.
The Bay of Pigs was a disastrous display of Kennedy’s inherent cowardice and invited The soviets to arm Cuba with missiles. To resolve the matter we agreed to remove missile from Greece. JFK was exactly the sort of weakling the soviets would want to keep in power.
