This dissertation has its focus in the investigation of the domestic variables that contributed to shape the american foreign policy towards Cuba in the first term of Cintons administration, from 1993 to 1996. The argument presented here is that the continuity of the animosity pattern that distinguished the relationship between Washington and Havana during the Cold War, is due to the political mobilization of a powerful portion of the cuban-american community. That segment, wich its major part is established in Florida, knew how to deal with the opportunities that the american political system grant to social groups that try to influence the policy-making process in the United States. This analysis combines the observation of the political action of social agents involved with the cuban politcs and the institutional machinery that translates it into stimuli to the american policy-making process, and try to establish the relation between the domestic policy and the american diplomacy to Cuba.
