An Operational Perspective on the Ethics of the Use of Autonomous Weapons

Abstract Rapid technological change is resulting in the development of ever increasingly capable autonomous weapon systems. As they become more sophisticated, the calls for developing restrictions on their use, up to and including their complete prohibition, are growing. Not unlike the call for restrictions on the sale and use of drones, most proposed restrictions are well-intentioned but are often ill-informed, with a high likelihood of degrading national security and putting additional lives at risk. Employed by experienced operators well-versed in the laws of armed conflict, autonomous weapons can advance the objectives of those who would prohibit their use. This essay takes an operational perspective to examine the role that autonomous weapon systems can play while complying with the laws of armed conflict. With responsible design and incorporation of applicable control measures, autonomous weapons will be able not just to comply but also to enhance the ethical use of force. This essay contends that efforts by the international community to use international legal means and/or institutions to over-regulate or even ban lethal autonomous weapons are counterproductive. It considers and describes the end-game results of the use of autonomous weapons in enhancing the application of both international law and human ethical values.
