How many times did the CIA try to kill Castro

In the sweltering summer of 1963, at the height of Cold War paranoia, CIA agent Robert "Bob" Maheu is sent to Cuba on a suicide mission: to humiliate Fidel Castro during a live television broadcast by dosing the dictator with LSD and making his beard fall out. But Bob bears the permanent scars of the MKULTRA program, a dark secret in the untold history of the United States' clandestine services. This is the (mostly) true story of how one agency's epic failure set the United States on a collision course with peace, told for the first time as a graphic novel.
