The violent use of armed, unmanned aircraft ('drones') is increasing worldwide, but uncertainty persists about the moral status of remote-control killing and why it should be restrained. Practitioners, observers and potential victims of such violence often struggle to reconcile it with traditional expectations about the nature of war and the risk to combatants. Addressing the ongoing policy concern that state use of drone violence is sometimes poorly understood and inadequately governed, the book's ethical assessments are not restricted to the application of traditional Just War principles, but also consider the ethics of artificial intelligence (AI), virtue ethics, and guiding principles for forceful law-enforcement. This edited collection brings together nine original contributions by established and emerging scholars, incorporating expertise in military ethics, critical military studies, gender, history, international law and international relations, in order to better assess the multi-faceted relationship between drone violence and justice.
