We propose a multi-step evaluation schema designed to help procurement agencies and others to examine the ethical dimensions of autonomous systems to be applied in the security sector, including autonomous weapons systems.

ABSTRACTIn this paper I argue that a remotely piloted aircraft pilot’s act of killing remotely, when it is done in the defense of another person, can be viewed as an act of sacrifice. This argument concludes from two premises. First, the RPA pilot faces psychological risk to self by carrying out such an action; second, the RPA pilot is motivated to some significant degree by something other than self-interest. Moreover, I challenge both the view that RPA represent merely an incremental (...) development in technology yielding an incremental expansion of the distance between the war-fighter and the target and the view that RPA is revolutionary in some fundamental sense. I instead argue that, based upon the natural geometric boundary imposed by the earth’s shape, RPA have maximized the physical distance between the war-fighter and the target and, over time, this fact will change, not only the psychological effects on the RPA pilot, but also the way we view killing and distance in general.

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)

One criticism of revisionist just war thought is often called the “contingent pacifism” objection. According to this objection, revisionist just war theory fails because it requires combatants on the just side to evaluate the moral responsibility for wrongful harm of each combatant on the unjust side to determine liability to defensive harming in each case. Combatants on the just side are epistemically barred from making these determinations. Moreover, many combatants on the unjust side (e.g., cooks and administrative soldiers) fail to (...) meet the threshold of responsibility for wrongful harm to make them liable to lethal defensive harm. Therefore, ex hypothesi, combatants on the just side will inevitably target enemy combatants who are not liable to be killed. In this paper, I offer a novel response to the contingent pacifism objection. I argue that, even on the revisionist account, participation in a military engaged in an unjust war is sufficient for liability to lethal defensive harm. First, I show merely signaling a threat of unjust harm—even if one lacks the means to actualize the threat—is sufficient for liability to defensive harm. Second, I argue that almost all participants in military activity signal a threat. Finally, I conclude that, in general, combatants on the unjust side of a conflict signal threats of unjust harm and are therefore liable to lethal defensive harming. This novel account of signaling-as-threatening disarms the contingent pacifist objection. (shrink)

In this article, I ask whether the martial virtues can serve as a role morality for soldiers. In it I compare three role morality theories and ask, according to each, whether the role of ‘soldier’ is the kind of role that generates a role morality. I conclude that the cultivation of the martial virtues may be a necessary condition for martial morality, but it is not a sufficient one. Finally, I present a positive account of a role morality for soldiers (...) that creates the space for crucial, if not traditionally martial, virtues such as respect for human life and human dignity.
