Cuban National Ballet prima ballerina assoluta and director, Alicia Alonso, arrives to a news conference with her husband, Pedro Simon, in Havana June 28, 2011. The Cuban National Ballet completed a month long tour to the United States. The tour was the latest in a series of cultural exchanges that began after U.S. President Barack Obama took office as the longtime ideological foes seek common ground they have been unable to find politically since Cuba's 1959 revolution.
