Luis Posada Carriles (http://en.wikipedia.org/wiki/Luis_Posada_Carriles) is an anti-Castro Cuban exile. In 1976 he bombed a Cuban airliner over Venezuela, killing 76 people. He was convicted of the crime in Venezuela, but escaped from prison and, later, helped supply arms to the U.S.-backed Nicaraguan Contras. In 2000 he and three associates were convicted of conspiring to assassinate Castro during a regional summit in Panama, but the Panamanian president pardoned all four of them.
On April 13, 2005, Posada applied for asylum in the U.S.; on May 3, the Venezuelan Supreme Court approved a request to extradite him to Venezuela. Whether he is actually in the U.S. at this time is unclear.
Assuming he can be located, should the U.S. grant him asylum, or extradite him to Venezuela?
Here is an interview with Ricardo Alacon, president of the Cuban National Assembly, setting forth Cuba’s views on the matter: http://www.democracynow.org/article.pl?sid=05/05/09/148248 As Alacon points out, since 9/11/01 the U.S. has been pushing the standard that no country should give harbor to terrorists or even friends or supporters of terrorism; and Posada is a terrorist by any reasonable definition of the term.
