On April 18, 1983, a van rigged with two thousand pounds of heavy explosives broke through the security perimeter of the American embassy in Lebanon and exploded, killing sixty-three people and decimating intelligence operations throughout the Middle East. Only one man inside the CIA possessed the courage and skills to rebuild the networks destroyed in the blast: William Buckley. Assigned as the new Beirut Station Chief, Buckley arrived in the war-torn city to find a CIA station in tatters and an intelligence playing-field unlike any other in the world; the veteran of the Cold War would now be learning Beirut rules. A field operative at heart, he delved into Beirut’s darkest corners, developing new sources and handling assets. Then, on October 23, a US Marine Corps barrack was destroyed in a plot masterminded by a young terrorist named Imad Mughniyeh. But even as President Reagan vowed revenge, Mughniyeh eyed a new target: Buckley. Beirut Rules is the pulse-by-pulse account of Buckley’s abduction, torture, and murder at the hands of Hezbollah terrorists. Drawing on never-before-seen US government documents, as well as interviews with Buckley’s co-workers, friends, and family, Fred Burton and Samuel M. Katz reveal how the relentless search for Buckley in the wake of his kidnapping ignited a war against terror that continues to shape the Middle East to this day.
