I'm still interested in why the US would think of withdrawing support from the Batista regime, when Castro's leadership in Cuba was by far the worse option. Consider how Castro blamed the United States for much of Cuba's troubles, and how it was able to seize control of many foreign companies.
How much do you think the Bay of Pigs invasion reflected JFK's early foreign policy? Remember that the invasion was planned during Eisenhower's administration, but carried out under JFK. Why, then, is the Cuban Missile Crisis that much more essential for JFK to solve?
