What are the individual and societal causes of terrorism? The book's great strength is its focus on new sources of data examined in new ways. The most compelling analysis in the book is of biographical information on operatives from Hezbollah and Hamas. This is a substantial contribution, offering insight into who becomes a terrorist and, as important, pushing terrorism studies in a productive new direction, toward microlevel data. The book provides a valuable service in dispelling the stereotype of the poor, ignorant terrorist.--Ethan Bueno de Mesquita, Science sakriti opis
