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)

Unmanned systems in military applications will often play a role in determining the success or failure of combat missions and thus in determining who lives and dies in times of war. Designers of UMS must therefore consider ethical, as well as operational, requirements and limits when developing UMS. I group the ethical issues involved in UMS design under two broad headings, Building Safe Systems and Designing for the Law of Armed Conflict, and identify and discuss a number of issues under (...) each of these headings. As well as identifying issues, I offer some analysis of their implications and how they might be addressed. (shrink)

We live in a world of rapidly advancing, revolutionary technologies that are not just reshaping our world and wars, but also creating a host of ethical questions that must be dealt with. But in trying to answer them, we must also explore why exactly is it so hard to have effective discussions about ethics, technology, and war in the first place? This article delves into the all-too-rarely discussed underlying issues that challenge the field of ethics when it comes to talking (...) about war, weapons, and moral conduct. These issues include the difficulty of communicating across fields; the complexity of real world dilemmas versus the seminar room and laboratory; the magnified role that money and funding sources play in shaping not just who gets to talk, but what they research; cross-cultural differences; the growing role of geographic and temporal distance issues; suspicion of the actual value of law and ethics in a harsh realm like war; and a growing suspicion of science itself. If we hope better to address our growing ethical concerns, we must face up to these underlying issues as well. (shrink)

Plans to automate killing by using robots armed with lethal weapons have been a prominent feature of most US military forces? roadmaps since 2004. The idea is to have a staged move from ?man-in-the-loop? to ?man-on-the-loop? to full autonomy. While this may result in considerable military advantages, the policy raises ethical concerns with regard to potential breaches of International Humanitarian Law, including the Principle of Distinction and the Principle of Proportionality. Current applications of remote piloted robot planes or drones offer (...) lessons about how automated weapons platforms could be misused by extending the range of legally questionable, targeted killings by security and intelligence forces. Moreover, the alleged moral disengagement by remote pilots will only be exacerbated by the use of autonomous robots. Leaders in the international community need to address the difficult legal and moral issues now, before the current mass proliferation of development reaches fruition. (shrink)

This article, an introduction to a special issue of the Journal of Military Ethics devoted to emerging military technologies, elaborates the present status of certain predictions about the future of warfare and combat made by postmodern essayist, Umberto Eco, during the First Gulf War in 1991. The development of military robotics, innovations in nanotechnology, prospects for the biological, psychological, and neurological ?enhancement? of combatants themselves, combined with the increasing use of nonlethal weapons and the advent of cyber warfare, have operationalized (...) the diffuse, decentralized, ?neoconnectionist? vision of warfare in the post-Clausewitzian, postmodern world that Eco first prophesied. On the one hand, such technologies threaten to make war ever more ubiquitous as the path of least resistance, rather than the option of last resort, for the resolution of political conflict. On the other hand, these same technologies offer prospects for lessening the indiscriminate destructive power of war, and enhance prospects for the evolution from state-centered conventional war, to discriminate law enforcement undertaken by international coalitions of peacekeeping forces.

Soldiers hiding in enemy territory that are discovered by civilians face acute ethical problems as to what to do about them. The law of armed conflict forbids harming civilians, yet if they are released they may well betray the soldiers and alert enemy forces that will kill or capture the soldiers. This is not just a theoretical problem; there are recent documented accounts of British and American soldiers who have found themselves in such a position and who have died because (...) they released the civilians. This paper argues that the ethical imperative here is to save the lives of both the soldiers and the civilians and that this should be the guiding principle in such cases. To this end, where possible, non-lethal means of restraint should be used on civilians to incapacitate them while the soldiers escape. (shrink)

We conclude this special issue with the Executive Summary and Command Brief from the McCain Conference, ?New Warriors/New Weapons: The Ethical Ramifications of Emerging Military Technologies?, as formulated by the conference convener, the Stockdale Center for Ethical Leadership at the US Naval Academy, and as prepared for the: Chief of Naval Operations and the Commandant, US Marine Corps (Ed).

Explores the moral dimensions of the current global role of the U.S. military.

Computers are already approving financial transactions, controlling electrical supplies, and driving trains. Soon, service robots will be taking care of the elderly in their homes, and military robots will have their own targeting and firing protocols. Colin Allen and Wendell Wallach argue that as robots take on more and more responsibility, they must be programmed with moral decision-making abilities, for our own safety. Taking a fast paced tour through the latest thinking about philosophical ethics and artificial intelligence, the authors argue (...) that even if full moral agency for machines is a long way off, it is already necessary to start building a kind of functional morality, in which artificial moral agents have some basic ethical sensitivity. But the standard ethical theories don't seem adequate, and more socially engaged and engaging robots will be needed. As the authors show, the quest to build machines that are capable of telling right from wrong has begun. -/- Moral Machines is the first book to examine the challenge of building artificial moral agents, probing deeply into the nature of human decision making and ethics.
