Frank E. Terpil (1939 – March 1, 2016) was a CIA agent born in Brooklyn, New York, U.S. in 1939, who was asked to leave the agency for misconduct in 1971. He then "went rogue", supplying things such as poison, weapons or mercenaries to all comers on a commercial, rather than ideological, basis.
After serving for a short time in the U.S. Army, Terpil joined the CIA in 1965, working in the Technical Services division, which adapted technology and weaponry for covert work. After departing from the CIA, he supplied dictators including Muammar Gaddafi of Libya and Idi Amin of Uganda. In 1980, a U.S. court indicted him on charges of large-scale illegal arms dealing. He skipped bail and left the U.S.; in 1981, he was sentenced in absentia to 53 years' imprisonment, with the judge describing his operations as "trade in death and destruction". However, he was never put on the FBI most wanted list. He moved to Lebanon, offering his services to Yasser Arafat of the PLO.
In 1982, journalist David Fanning and director Antony Thomas produced Frank Terpil: Confessions of a Dangerous Man, which won the Emmy Award for best investigative documentary.
When Israel invaded Lebanon in 1982, he moved to Cuba, at that time in dispute with the U.S. and subject to an embargo. Terpil worked for the General Intelligence Directorate, trying to persuade CIA agents to defect, though he was not ideologically aligned with the government. Terpil and fugitive Robert Vesco joined forces and offered their network of contacts to the Cuban government.
