US intelligence agency has since 1945 succeeded in deposing or killing a string of leaders, but was forced to cut back after a Senate investigation in the 1970s
Some of the most notorious of the CIA’s operations to kill world leaders were those targeting the late Cuban president, Fidel Castro. Attempts ranged from snipers to imaginative plots worthy of spy movie fantasies, such as the famous exploding cigars and a poison-lined scuba-diving suit.
But although the CIA attempts proved fruitless in the case of Castro, the US intelligence agency has since 1945 succeeded in deposing or killing a string of leaders elsewhere around the world – either directly or, more often, using sympathetic local military, locally hired criminals or pliant dissidents.
According to North Korea’s ministry of state security, the CIA has not abandoned its old ways. In a statement on Friday, it accused that the CIA and South Korea’s intelligence service of being behind an alleged recent an assassination attempt on its leader Kim Jong-un.
