The United States Army’s Future Combat Systems Project, which aims to manufacture a “robot army” to be ready for deployment by 2012, is only the latest and most dramatic example of military interest in the use of artificially intelligent systems in modern warfare. This paper considers the ethics of a decision to send artificially intelligent robots into war, by asking who we should hold responsible when an autonomous weapon system is involved in an atrocity of the sort that would normally (...) be described as a war crime. A number of possible loci of responsibility for robot war crimes are canvassed; the persons who designed or programmed the system, the commanding officer who ordered its use, the machine itself. I argue that in fact none of these are ultimately satisfactory. Yet it is a necessary condition for fighting a just war, under the principle of jus in bellum, that someone can be justly held responsible for deaths that occur in the course of the war. As this condition cannot be met in relation to deaths caused by an autonomous weapon system it would therefore be unethical to deploy such systems in warfare. (shrink)

The first section of this article argues that the best-known definition of physical courage, stemming from Aristotle's Nicomachean Ethics, is less than fit for today's military. Having done so, a short outline is given of more scientific approaches to physical courage, drawing mainly on insights offered by psychologists, and of the problems that are inherent to these approaches. Subsequently, the article turns to a topic that is often paid lip service to in the military, yet remains somewhat hard to pin (...) down: moral courage. Although both forms of courage are intertwined, they are so in a less straightforward manner than is often thought. The way the development of physical courage in today's military is undertaken, for instance, contributes little to the development of moral courage. (shrink)

ABSTRACTThis article explores the relationship between the operation of combat drones and the martial virtue courage. The article proceeds in three parts. Part one develops a brief account of virtue generally, and the martial virtue courage in particular. Part two discusses why critics suggest that drone operation does not fit the orthodox conceptualization of courage and, in some instances, even erodes the virtue. Part three explores how these criticisms are flawed. This section of the paper goes on to argue that (...) the criticisms are predicated on a twofold misunderstanding. The first involves improperly truncated conceptualizations of courage, which are, in part, predicated upon a narrow definition of risk. From this narrow definition of risk springs the conclusion that drone operation must be riskless. The second misunderstanding follows from the first and involves the failure to grasp properly how courage can be cultivated and required in drone operation. The paper concludes with a discussion of how, pr.. (shrink)

This article contends that in crucial respects effective soldiers are ethical soldiers, that good soldiers in the military sense are good soldiers in the moral sense, and that this is so for quite traditional reasons. The thesis is defended by identifying and then resolving basic paradoxes regarding what soldiers must be trained to do or be, e.g.: be trained to kill but also not to be brutal; be trained to react in combat situations almost automatically but also to deliberate and (...) decide if a command is unlawful; as peacekeepers, be trained to be impartial but also to know right from wrong and be firmly committed to upholding the former and opposing the latter. It is shown that contradictory things are not really thus being called for. With the aid of a blend of deontology and virtue theory, it is argued that certain standard qualities of effective soldiers have an associated moral dimension. For example, true military courage implies an unwillingness to engage in cruelty; the self‐control on which success of missions depends implies eschewing motives of personal vengeance; and the capacity for comprehending complex equipment and data implies a mentality for assessing the validity of orders.

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)

This paper makes the case for arms control regimes to govern the development and deployment of autonomous weapon systems and long range uninhabited aerial vehicles.
