In late 2014, President Obama and Raúl Castro announced that the United States and Cuba would restore full diplomatic ties for the first time in more than 50 years. And late last month, of course, Fidel Castro died at age 90. So what happens next in U.S.-Cuban relations? Where do we go from here? Our guest on ST recently gave an address at the Tulsa Committee on Foreign Relations that was focused on such questions. Ambassador Dennis K. Hays (ret.) joins us in the studio; over the course of his long career, he has served in the Foreign Service; the U.S. Department of State in Washington; the U.S. Embassy in Bujumbura, Burundi; and the U.S. Embassy in Georgetown, Guyana. He was also the Coordinator for Cuban Affairs during the time of the Cuban Rafter Crisis. Ambassador Hays retains a strong interest in Cuba and our relationship with that country. He frequently speaks about and/or debates the subject on national news programs.
