I will go to my grave profoundly grateful that John Kennedy was President during the Cuban missile crisis. I think that is a saving event of the highest magnitude. Were Nixon, or Goldwater, or Reagan, or GWB, Cheney or a McCain type, in fact any Republican president we would have had a nuclear war with Russia.
The Russian troops in Cuba had nuclear weapons under local control with instructions to use them in the event of a US invasion. Most of Kennedy’s advisors wanted an invasion. (Interestingly, Kennedy surrounded himself with advisors of all persuasions, not the yes-men parrots every Republican president since Eisenhower except possibly for Ford has had around them. Have to be ideologically pure in their lock-step style, modeled on Hitler’s Nazis.) You can imagine what Republicans would have wanted.
With an American invading force off-shore, a Russian officer would have ordered a nuke fired off. The pressure to fire off a nuke at Russia would have been irresistable, and off we’d have gone.
I don’t think we give enough credit to Kennedy for his approach to that conflict. That I am writing this is a credit to him personally.
