RFK Jr. speaks out on Cuba
In an important article published by the Inter Press Service news agency Robert F. Kennedy Jr., the nephew of President John F. Kennedy, highlights an important point about U.S.-Cuba relations that President Obama normalized last week: The CIA opposed President Kennedy’s efforts to do the same 51 years ago.

RFK Jr., an environmental attorney, is right that the CIA knew about JFK’s interest in normalizing relations, and opposed it.
“The president had asked his speechwriter, Theodore Sorensen, for language that would open a door to the Cuban leader, although, as Sorensen later observed, the audience was a very tough anti-Castro group.'”
