Five decades after Fidel Castro toppled a U.S.-backed dictator to take power in Cuba, the Cold War rivalry with Washington could be thawing as President-elect Barack Obama looks to ease sanctions against the communist-run island, according to Reuters. Obama has made clear he favors relaxing restrictions on family travel and cash remittances by Cuban Americans to Cuba, which this week marks the 50th anniversary of Castro's revolution. Obama could also reverse other steps taken by outgoing President George W. Bush to tighten sanctions on Cuba, such as the prepayment of food imports from the United States, and he is expected to restore migration talks broken off by Bush. Experts on Cuba believe modest changes in policy will come quickly, but stop short of lifting the trade embargo first imposed in 1962 or allowing all Americans to travel to the island 90 miles (145 km) off the coast of Florida. Obama, who takes office on Jan. 20, will be the 11th U.S. president to deal with the Cuban revolution in a dispute that has outlived the Cold War and took the world to the brink of nuclear war during the 1962 Soviet missile crisis. On the campaign trail, Obama said the embargo should stay in place to press for democratic reforms in Cuba, but he said he was open to dialogue with the Cuban leadership. Cuba has welcomed Obama's proposals as a good first step and President Raul Castro, who took over from his older brother Fidel Castro early this year, has offered to free political dissidents in exchange for the release of five convicted Cuban spies in U.S. prisons as "gestures" to help set up a meeting with Obama. While such an exchange is unlikely and Obama will not end the embargo without major concessions from Castro, his arrival is seen by some as opening a window of opportunity for improved relations at a time of political transition in Cuba. "The potential for change is more real than ever," said Katrin Hansing, associate director at the Florida International University's Cuban Research Institute.
