A visitor looks a photograph of former Cuban leader Fidel Castro, part of an exhibit titled “To the Brink: JFK and the Cuban Missile Crisis” at the John F. Kennedy Library in Boston, Massachusetts December 18, 2014.

F. Kennedy – also a Democrat – betrayed them during the failed 1961 Bay of Pigs invasion. REUTERS/Brian Snyder (UNITED STATES – Tags: POLITICS)
