Drones are the iconic military technology of many of today's most pressing conflicts, a lens through which U.S. foreign policy is understood, and a means for discussing key issues regarding the laws of war and the changing nature of global politics. Drones have captured the public imagination, partly because they project lethal force in a manner that challenges accepted rules, norms, and moral understandings. Drone Wars presents a series of essays by legal scholars, journalists, government officials, military analysts, social scientists, and foreign policy experts. It addresses drones' impact on the ground, how their use adheres to and challenges the laws of war, their relationship to complex policy challenges, and the ways they help us understand the future of war. The book is a diverse and comprehensive interdisciplinary perspective on drones that covers important debates on targeted killing and civilian casualties, presents key data on drone deployment, and offers new ideas on their historical development, significance, and impact on law and policy. Drone Wars documents the current state of the field at an important moment in history when new military technologies are transforming how war is practiced by the United States and, increasingly, by other states and by non-state actors around the world.
