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)

The nature of warfare is changing. Increasingly, developments in military technology are removing soldiers from the battlefield, enabling war to be waged from afar. Bombs can be dropped from unmanned drones flying above the range of retaliation. Missiles can be launched, at minimal cost, from ships 200 miles to sea. Micro Air Vehicles, or 'WASPS', will soon be able to lethally attack enemy soldiers. Though still in the developmental stage, progress is rapidly being made towards autonomous weaponry capable of selecting, (...) pursuing, and destroying targets without the necessity for human instruction. These developments have a profound — and as yet under-analysed — impact on just war theory. I argue that a state under attack from remote weaponry is unable to respond in the traditional, just war sanctioned, method of targeting combatants on the battlefield. This restriction of options potentially creates a situation whereby a state is either coerced into surrender, or it must transgress civilian immunity. Just war theory in conditions of remote warfare therefore either serves the interests of the technologically advanced by demanding the surrender of targeted states, or else it becomes redundant.

Abstract The debate about the ethics of uninhabited aerial vehicles (UAVs) is failing to keep pace with the rise of the technology. Therefore, all the key players, including ethicists, lawyers, and roboticists, are keen to offer their views on the use of these drone aircraft. Some are opposed to their use, citing a range of ethical, legal and operational issues, while others argue for their ethically mandated use. B.J. Strawser fits into this latter category. He develops a principle of ?unnecessary (...) risk?, from which he argues that we have an ethical obligation to employ UAVs if we can do so without incurring a loss of capability. Strawser defends his argument against a number of potential objections, most questionably, the argument that the use of distance weaponry such as drones, against another state without distance weaponry, crosses some moral threshold that makes the combat immoral. Utilising Jeff McMahan's work on the inequality of combatants, Strawser essentially argues that there are no grounds for a ?fair fight?. However, this paper will argue that it is not so easy to overturn the doctrine of the moral equality of combatants, nor dismiss the problem with asymmetry. It will demonstrate that if the asymmetry reaches a certain level, the justification for resorting to war may be removed and some sort of policing action may remain the only option. (shrink)

In this paper we examine the ethical implications of emerging Nanotechnologically Enhanced Combat Systems (or 'NECS'). Through a combination of materials innovation and biotechnology, NECS are aimed at making combatants much less vulnerable to munitions that pose a lethal threat to soldiers protected by conventional armor. We argue that increasing technological disparities between forces armed with NECS and those without will exacerbate the ethical problems of asymmetric warfare. This will place pressure on the just war principles of jus in bello, (...) by encouraging the resort to tactics that either (i) make it more difficult to respect these principles or (ii) directly violate them, by virtue of attacking non-combatants or creating disproportionate numbers of casualties without a clear military goal.
