The moral right to act in self-defense seems to be unproblematic: you are allowed to kill an aggressor if doing so is necessary for saving your own life. Indeed, it seems that from the moral standpoint, acting in self-defense is doing the right thing. Thanks, however, to works by George Fletcher and Judith Thomson, it is now well known how unstable the moral basis of the right to self-defense is. We are in the dark with regard to one of the (...) most basic problems raised by this right, namely: the problem of the innocent aggressor. The disturbing question is simple enough: Is a potential victim allowed to kill, in self-defense, a morally innocent aggressor? (shrink)

In war there is a phenomenon known as the Naked Soldier problem (NS). A combatant discovers a vulnerable enemy combatant who is unable to defend himself and usually unaware of the combatant’s presence. This enemy combatant is not presently engaged in fighting and not threatening the lives of others. While killing the NS is legally permissible, the question I address in this essay is whether or not there can be a moral justification for doing so. I think such a moral (...) justification is lacking, and there are only excuses for killing the NS. In this essay, I distinguish between a justification and an excuse and then I examine four traditional reasons given for the acceptability of killing in war to see if any of them are (a) justifications for killing in war in general and (b) justifications for killing the Naked Soldier, specifically.

This article presents a novel theory of noncombatant immunity that can serve as a practical guide for soldiers in the field. It improves on existing theories by justifying why and when an innocent...

In war a soldier behaving properly should take into account a universal requirement not to kill, to be applied strictly in dealing with civilians, but at the same time to support the exception of taking the life of enemy combatants as an act of selfdefense. This is the usual way to distinguish morally the proper treatment to soldiers and civilians. In this article the author criticizes it and outlines a different way to understand and justify the moral distinction mentioned.

Commonsense moral thought holds that what makes terrorism particularly abhorrent is the fact that it tends to be directed toward innocent victims. Yet contemporary philosophers tend to doubt that the concept of innocence plays any significant role here, and to deny that prohibitions against targeting noncombatants can be justified through appeal to their moral innocence. I argue, however, that the arguments used to support these doubts are ultimately unsuccessful. Indeed, the philosophical positions in question tend to misunderstand the justification of (...) both the prohibition against targeting noncombatants, and that of the permission to attack combatants, for which the paper offers a new account. Such misunderstandings make it all too easy to justify both terrorist actions and morally objectionable actions on the part of nations at war. Taking proper account of the role of innocence in the context of armed conflict will alter our ordinary ways of thinking about the ethics of war, with respect to both jus in bello and jus ad bellum.

The reductivist view of war holds that the moral rules of killing in war can be reduced to the moral rules that govern killing between individuals. Noam Zohar objects to reductivism on the grounds that the account of individual self-defence that best supports the rules of war will inadvertently sanction terrorist killings of non-combatants. I argue that even an extended account of self-defence—that is, an account that permits killing at least some innocent people to save one's own life—can support a (...) prohibition on terrorism, provided that it distinguishes between direct and indirect threats. What such an account cannot support is the blanket immunity of non-combatants to defensive killing. If a non-combatant is morally responsible for indirectly threatening in an unjust war, she can be liable to defensive killing. However, this gives us reason to revise our account of permissible killing in war, rather than to reject the reductivist account. (shrink)

This article challenges the tendency exhibited in arguments by Michael Ignatieff, Jeremy Waldron, and others to treat the Law of Armed Conflict as the only valid moral frame of reference for guiding armed rebels with just cause. To succeed, normative language and principles must reflect not only the wrongs of ‘terrorism’ and war crimes, but also the rights of legitimate rebels. However, these do not always correspond to the legal privileges of combatants. Rebels are often unlikely to gain belligerent recognition (...) and might sometimes have strong moral reasons to exceed the rights of regular combatants. Where this gives rise to tensions between morality and the LOAC, a decision is needed to determine which to follow. Setting aside the idea of suppressing just war theory altogether in favour of a more purely regulatory approach to war and reforming law in the direct light of moral theory, I question the attempt by Waldron to argue that moral weight of the legal conventions at the heart of the LOAC trump any moral reasons there might be for breaching them. Even if non-combatant immunity is, as Waldron suggests, a deadly serious convention, I argue that war is justified only if pursued for the sake of deadly serious causes which may even be serious enough to oblige agents to break the law. A political theory of the ethics of war is needed to mediate between the moral and legal in such cases where they cannot be reconciled directly. (shrink)

Over the past 20 years, there has been a huge amount of work on which things you can kill in self‐defense and why. This paper surveys that work.
