This book chapter addresses two questions. First, can targeted killing by drones in non-battlefield zones be justified on basis of just war theory? Second, will the proliferation and expansion of combat drones in warfare, including the introduction of autonomous drones, be an obstacle to initiating or executing wars in a just manner in the future? The first question is answered by applying traditional jus ad bellum and jus in bello principles to the American targeted killing campaign in Pakistan; the second (...) question is answered on basis of principles of “just military preparedness” or jus ante bellum, a new category of just war thinking. It is concluded that an international ban on weaponized drones is morally imperative and, certainly, that an international treaty against autonomous lethal weapons should be adopted. (shrink)

A number of recent and influential accounts of military ethics have argued that there exists a distinctive “role morality” for members of the armed services—a “warrior code.” A “good warrior” is a person who cultivates and exercises the “martial” or “warrior” virtues. By transforming combat into a “desk job” that can be conducted from the safety of the home territory of advanced industrial powers without need for physical strength or martial valour, long-range robotic weapons, such as the “Predator” and “Reaper” (...) drones fielded by the United States, call the relevance of the “martial virtues” into question. This chapter investigates the implications of these developments for conceptions of military virtue and, consequently, for the future of war. (shrink)

A variety of ethical objections have been raised against the military employment of uninhabited aerial vehicles (UAVs, drones). Some of these objections are technological concerns over UAVs abilities’ to function on par with their inhabited counterparts. This paper sets such concerns aside and instead focuses on supposed objections to the use of UAVs in principle. I examine several such objections currently on offer and show them all to be wanting. Indeed, I argue that we have a duty to protect an (...) agent engaged in a justified act from harm to the greatest extent possible, so long as that protection does not interfere with the agent's ability to act justly. UAVs afford precisely such protection. Therefore, we are obligated to employ UAV weapon systems if it can be shown that their use does not significantly reduce a warfighter's operational capability. Of course, if a given military action is unjustified to begin with, then carrying out that act via UAVs is wrong, just as it would be with any weapon. But the point of this paper is to show that there is nothing wrong in principle with using a UAV and that, other things being equal, using such technology is, in fact, obligatory. (shrink)
