Latin America and Communism

Arguing that "those who make peaceful revolution impossible, will make violent revolution inevitable,"Kennedy sought to contain communism in Latin America by establishing the Alliance for Progress, which sent aid to troubled countries and sought greater human rights standards in the region. He worked closely with Governor of Puerto Rico Luis Muñoz Marín for the development of the Alliance of Progress, and began working towards the autonomy of the Commonwealth of Puerto Rico.
When the president took office the Eisenhower administration, through the CIA, had begun formulating plans for the assassination of Castro in Cuba and Rafael Trujillo in the Dominican Republic. Kennedy privately instructed the CIA that any such planning must include plausible deniability by the U.S. His public position was in opposition.

In June 1961 the Dominican Republic's leader was assassinated; in the days following the event, Undersecretary of State Chester Bowles led a cautious reaction by the nation. Robert Kennedy, who saw an opportunity for the U.S., called Bowles "a gutless bastard" to his face.
