Presidents Dwight Eisenhower and John Kennedy were very concerned about the communist takeover of Cuba because A. communists were now more of a threat to the United States. This became much more apparent under Kennedy's presidency when Castro's Cuba began receiving nuclear weapons from the Soviet Union. Cuba is only 90 miles away from the southern portion of Florida and thus the presence of a communist government with nuclear missiles that close to the United States made them a threat.
