Add to that the continuing myth that the Soviets removed the missiles because of the blockade and Kennedy ordering Defcon 2. The real reason was Castro and Guevara looking to take control of the missiles and launch them, starting WW3. Kruschev reconsidered the missiles in Cuba, and got them out.
LOL, I thought Kruschev was just responding to Bertrand Russell’s famous, frenetic letter to him and Kennedy, pleading for peace. Old Bertie was the original peacenik, and in fact invented the peace symbol, fashioned to represent an ICBM pointed downward.
