This riveting account examines the new Islamic radicalism through the stories of its flag-bearers, including a U.S. Air Force colonel who once served Saddam Hussein, a provincial bookworm who declared himself caliph of all Muslims, and bin Laden’s own beloved son Hamza, a prime candidate to lead the organization his late father founded. lays bare the psychology and inner workings of al-Qaeda, the Islamic State, and their spawn, and shows how the spread of terror can be stopped.
