What is the importance of Washington D.C. in the book, Miami?

Washington figures prominently in this book, despite the book's title. Didion shows how deeply implicated the United States government is in 'la lucha,' not because Washington has given thorough and effective support to the Cuban exiles' cause but because of the history of collaboration, manipulation, political pandering, and other strategies employed by Washington to make use of the ideological fervor of the Miami Cubans. Didion shows how broken promises made by Presidents Kennedy and Reagan at different times have become embedded in the Cuban exile's psyche, creating environments of distrust, feelings of betrayal, yet continuously drawing the exiles into Washington plots against Communism in Latin America.
