Although most styles of military ethics are hybrids that draw on multiple ethical theories, they are usually based primarily on the model of Aristotelian virtue ethics. Virtue ethics is well-suited for regulating the conduct of soldiers who have to make quick decisions on the battlefield, but its applicability to military personnel is threatened by the growing use of unmanned weapon systems. These weapons disrupt virtue ethics’ institutional and cultural basis by changing what it means to display virtue and transforming the (...) roles soldiers perform and the nature of the military profession itself. I argue that in light of these challenges to virtue ethics, at least as it is traditionally understood within the armed forces, soldiers operating unmanned weapons require a more heavily rule-based approach to military ethics.

In 2014, Colonel M. Shane Riza published an article in this journal arguing that remotely piloted aircraft and robotic weapons threaten the US Air Force’s warrior ethos. Riza has clearly articulated the sentiments of one side of a vibrant debate within our service. This paper presents an alternative view; a view held by some who have experienced these new forms and tools of war, and who have wrestled with their implications first-hand. In this paper, we address some methodological concerns with (...) Riza’s approach and then engage some misunderstandings about RPA’s relationship to military history and to risk. The second part of this paper takes a close look at some of the early Just War thinkers to determine what implications the tradition may have on the warrior ethos. We propose, as an alternative to Riza’s position, a return to an ethos grounded in humility, charity, and a conception of war as a last resort; in short, a return to the Just Warrior Ethos. (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)

This book assesses the ethical implications of using armed unmanned aerial vehicles in contemporary conflicts. The American way of war is trending away from the heroic and towards the post-heroic, driven by a political preference for air-powered management of strategic risks and the reduction of physical risk to US personnel. The recent use of drones in the War on Terror has demonstrated the power of this technology to transcend time and space, but there has been relatively little debate in the (...) United States and elsewhere over the embrace of what might be regarded as politically desirable and yet morally worrisome: risk-free killing. Arguably, the absence of a relationship of mutual risk between putative combatants poses a fundamental challenge to the status of war as something morally distinguishable from other forms of violence, and it also undermines the professional virtue of the warrior as a courageous risk-taker. This book considers the use of armed drones in the light of ethical principles that are intended to guard against unjust increases in the incidence and lethality of armed conflict. The evidence and arguments presented indicate that, in some respects, the use of armed drones is to be welcomed as an ethically superior mode of warfare. Over time, however, their continued and increased use is likely to generate more challenges than solutions, and perhaps do more harm than good. This book will be of much interest to students of the ethics of war, airpower, counter-terrorism, strategic studies and security studies in general. (shrink)

This book is an examination of the permissions, prohibitions and obligations found in just war theory, and the moral grounds for laws concerning war. Pronouncing an action or course of actions to be prohibited, permitted or obligatory by just war theory does not thereby establish the moral grounds of that prohibition, permission or obligation; nor does such a pronouncement have sufficient persuasive force to govern actions in the public arena. So what are the moral grounds of laws concerning war, and (...) what ought these laws to be? Adopting the distinction between jus ad bellum and jus in bello, the author argues that rules governing conduct in war can be morally grounded in a form of rule-consequentialism of negative duties. Looking towards the public rules, the book argues for a new interpretation of existing laws, and in some cases the implementation of completely new laws. These include recognising rights of encompassing groups to necessary self-defence; recognising a duty to rescue; and considering all persons neither in uniform nor bearing arms as civilians and therefore fully immune from attack, thus ruling out 'targeted' or 'named' killings. This book will be of much interest to students of just war theory, ethics of war, international law, peace and conflict studies, and Security Studies/IR in general. (shrink)
