Historian Stephen Rabe writes that "scholars have understandably focused on…the Bay of Pigs invasion, the US campaign of terrorism and sabotage known as Operation Mongoose, the assassination plots against Fidel Castro, and, of course, the Cuban Missile Crisis. Less attention has been given to the state of US-Cuban relations in the aftermath of the missile crisis." Rabe writes that reports from the Church Committee reveal that from June 1963 onward, the Kennedy administration intensified its war against Cuba while the CIA integrated propaganda, "economic denial," and sabotage to attack the Cuban state as well as specific targets within.[5] One example cited is an incident where CIA agents, seeking to assassinate Castro, provided a Cuban official, Rolando Cubela Secades, with a ballpoint pen rigged with a poisonous hypodermic needle.[5] At this time, the CIA received authorization for 13 major operations in Cuba, including attacks on an electric power plant, an oil refinery, and a sugar mill.[5] Rabe has argued that the "Kennedy administration... showed no interest in Castro's repeated request that the United States cease its campaign of sabotage and terrorism against Cuba.
