PORT-OF-SPAIN, Trinidad - It looks like the United States and Cuba are getting unstuck, taking tentative steps in a diplomatic dance that could resolve a half-century of hostility.

Within the last 24 hours, Barack Obama, Raul Castro and Hillary Rodham Clinton have made a flurry of conciliatory gestures, and expectations for a thaw are soaring.

The head of the Organization of American States acknowledged the momentum today by saying he'll ask his group to readmit Cuba 47 years after it suspended the communist country to support the U.S. trade embargo. Caribbean leaders said they would gladly provide neutral ground for U.S.-Cuba talks.

The U.S. secretary of state not only called America's Cuba policy a failure, but characterized the Cuban President's latest comments as a "very welcome gesture."
