Who is Imad Fa'iz Mughniyah from See No Evil: The True Story of a Ground Soldier in the CIA's War on Terrorism and what is their importance?

Imad Fa'iz Mughniyah was a Shi'a Muslim from southern Lebanon. He was responsible for the kidnapping of CIA chief Bill Buckley and the other hostages who were held at a compound in Kurdish territory in northern Iraq that had been commandeered by the Iranians. When a CIA chief came to Robert for advise on how to handle Mughniyah in attempting to free the hostages, Robert suggested that the US should hit Mughniyah where it would hurt the most—his family. But Mughniyah was elusive and was difficult to keep track of. The embassy bombing in Beirut where six CIA agents lost their lives haunted Robert Baer for decades. Robert found links between Mughniyah and the bombing.
