For weeks, rumors  had been swirling around Washington and Havana that changes in U.S.  policy toward Cuba were in the works. Then, on December
                                    17, President Barack Obama and President Raúl Castro made simultaneous announcements of a radical change in relations between the two countries. Not only would USAID subcontractor
                                    Alan Gross and the three remaining Cubans spies of the Cuban Five  be going home -- which was the deal most observers had anticipated --  but Cuba and the United States also would expand
                                    trade and travel, and  restore full diplomatic relations. 
Although President Obama had  said repeatedly that he thought
                                    the old policy of isolation and  hostility toward Havana no longer made any sense, for six years he did  little to change
                                    it. Then in one announcement, he reversed 50 years of  U.S. policy, completely revamping the basic framework and premises
                                    of  the relationship. What happened to finally break the log-jam?
First, the political calculus changed. Recent polls
                                    from the Atlantic Council and Florida International University  showed that the public in general and Cuban-Americans in particular  supported reconciliation between Washington and Havana.
                                    Comments by  prominent exiles like Alfie Fanjul and the Barcardi family  expressing a desire to do business in Cuba showed that even stalwart  anti-Castro leaders in the community were ready for
                                    change. 
Hillary Clinton's public declaration that the embargo ought to be lifted, and former Governor Charlie Crist's promise  to go to Cuba during his gubernatorial run indicated that seasoned  politicians recognized the shifting mood of the electorate.
                                    Weighing the  evidence, the White House concluded that Cuba was no longer the third  rail of Florida politics. And of course,
                                    Obama doesn't have to run for  re-election anyway.

Having just coauthored a book with Peter Kornbluh on secret diplomacy (Back Channel to Cuba: The Hidden History of Negotiations between Washington and Havana),  I wondered in the weeks leading up to the historic announcement whether  secret talks might already be underway with Cuba.
                                    Now we know that  these talks followed a classic pattern: only a handful of officials knew  about the negotiations; the talks
                                    were held outside the country to  avoid discovery; and the bargaining went on for months to produce an  accord. But the scope
                                    of the resulting agreements is unprecedented in  U.S.-Cuban relations, and the negotiators on both sides deserve enormous
                                     credit for bringing the talks to fruition. 
In April, the  presidents of the Americas will convene in Panama for their
                                    Seventh  Summit, and for the first time Cuba will be included. Obama's new Cuba  policy is extraordinarily popular in Latin
                                    America, and the good will it  has engendered will go far to revitalize U.S. relations with the entire  hemisphere. The summit
                                    will also give Raúl Castro and Barack Obama an  opportunity to talk in person about the next steps in the new  relationship.
When
                                    Richard Nixon went to China in 1972, the world  breathed a sigh of relief that U.S. policy was finally getting back in  touch
                                    with reality.  On December 17, Barack Obama took an equally bold  step by finally ending the cold war in the Caribbean. The
                                    reaction at  home and abroad has been overwhelmingly positive, a few churlish  conservative critics notwithstanding. Many
                                    loose ends remain to be tied  up before the United States and Cuba will have fully normal relations,  but a new chapter has
                                    been opened, and the idea of going back to the  past already seems ridiculous and impossible.
