Beneath the histories of religious traditions, from biblical wars to crusading ventures and great acts of martyrdom, violence has lurked as a shadowy presence. Images of death have never been far from the heart of religion's power to stir the imagination. The author asks one of the most important and perplexing questions of our age: Why do religious people commit violent acts in the name of their god, taking the lives of innocent victims and terrorizing entire populations? This, the first comparative study of religious terrorism, explores incidents such as the World Trade Center explosion, Hamas suicide bombings, the Tokyo subway nerve gas attack, and the killing of abortion clinic doctors in the United States. Incorporating personal interviews with World Trade Center bomber Mahmud Abouhalima, Christian Right activist Mike Bray, Hamas leaders Sheik Yassin and Abdul Azis Rantisi, and Sikh political leader Simranjit Singh Mann, among others, the author takes the reader into the mindset of those who perpetrate and support violent acts. In the process, he helps us understand why these acts are often associated with religious causes and why they occur with such frequency at this moment in history. This book places these acts of violence in the context of global political and social changes, and posits them as attempts to empower the cultures of violence that support them. He analyzes the economic, ideological, and gender-related dimensions of cultures that embrace a central sacred concept, cosmic war, and that employ religion to demonize their enemies. The narrative is engaging, incisive, and sweeping in scope. He convincingly shows that while, in many cases, religion supplies not only the ideology but also the motivation and organizational structure for the perpetrators of violent acts, it also carries with it the possibilities for peace.
