"For decades, Mark Juergensmeyer has been studying the rise of religious violence around the world, including groups like ISIS and Christian militias that have been involved in acts of terrorism. Over the years he came to realize that war is the central image in the worldview of virtually every religious movement engaged in violent acts. Behind the moral justification of using violence are images of great confrontations of war on a transcendent scale. This book explores the dark attraction between religion and warfare and explains why religion needs war and war needs religion. Virtually every religious tradition leaves behind it a bloody trail of stories, legends and images of war, and most wars call upon the divine for blessings in battle. This book probes the connection between religion and warfare -- the remarkably similar alternative realities that are created in the human imagination by both religious ideas and images of war in response to crises both personal and social. Based on the authors thirty years of field work interviewing activists involved in religious-related terrorist movements around the world, this book explains why desperate social conflict and personal fears lead to extremes of both religion and war, and why invariably God is thought to be engaged in battle." --.
