Those of us who are not pacifists face an obvious challenge. Common-sense morality contains a stringent constraint on intentional killing, yet war involves homicide on a grand scale. If wars are to be morally justified, it needs be shown how this conflict can be reconciled. A major fault line running throughout the contemporary just war literature divides two approaches to attempting this reconciliation. On a ‘reductivist’ view, defended most prominently by Jeff McMahan, the conflict is largely illusory, since such killing (...) can be justified by aggregating individuals’ ordinary permissions to use force in self- and other-defence. In opposition, a rival ‘nonreductivist’ approach holds that these considerations are insufficient for the task. One prominent version of non-reductivism grounds the permission to kill in combatants’ membership in certain kinds of group or association. The key claim is that participation in certain morally important relationships can provide an independent source of permission for killing in war. This paper argues that non-reductivism should be rejected. It does so by pushing a dilemma onto non-reductivists: if they are successful in showing that the relevant relationships can generate permissions to kill in war, they must also jettison the most intuitive restrictions on conduct in war—the constraint on intentionally killing morally innocent non-combatants most saliently. Since this conclusion is unacceptable, non-reductivism should be rejected. (shrink)

Since its earliest incarnations, just war theory has included the requirement that war must be initiated and waged by a legitimate authority. However, while recent years have witnessed a remarkable resurgence in interest in just war theory, the authority criterion is largely absent from contemporary discussions. In this paper I aim to show that this is an oversight worth rectifying, by arguing that the authority criterion plays a much more important role within just war theorising than is commonly supposed. As (...) standardly understood, the authority criterion provides a necessary condition for the justification of the resort to war, but has no bearing on the question of permissible conduct in war. In opposition, I argue for an alternative interpretation of the criterion, which attributes to it a fundamental role in assessing this latter question. With this revised interpretation in place, I then demonstrate its advantages by applying it to the practical issue of armed conflicts that are initiated and fought by non-traditional belligerents. While several theorists have recognised that this common feature of modern armed conflict poses a challenge to mainstream just war theory in general—and to the authority criterion in particular—I argue that existing discussions frequently misconstrue the nature of the challenge, since they assume the standard interpretation of the authority requirement and its role within the theory. I then show that the revised interpretation provides a clearer account of both the challenge posed by non-traditional belligerency and the kind of response that it requires. (shrink)

Jeff McMahan has argued against the moral equivalence of combatants (MEC) by developing a liability-based account of killing in warfare. On this account, a combatant is morally liable to be killed only if doing so is an effective means of reducing or eliminating an unjust threat to which that combatant is contributing. Since combatants fighting for a just cause generally do not contribute to unjust threats, they are not morally liable to be killed; thus MEC is mistaken. The problem, however, (...) is that many unjust combatants contribute very little to the war in which they participate—often no more than the typical civilian. Thus either the typical civilian is morally liable to be killed, or many unjust combatants are not morally liable to be killed. That is, the liability based account seems to force us to choose between a version of pacifism, and total war. Seth Lazar has called this “The Responsibility Dilemma”. But I will argue that we can salvage a liability-based account of war—one which rejects MEC—by grounding the moral liability of unjust combatants not only in their individual contributions but also in their complicit participation in that war. On this view, all enlistees, regardless of the degree to which they contribute to an unjust war, are complicitously liable to be killed if it is necessary to avert an unjust threat posed by their side. This collectivized liability based account I develop avoids the Responsibility Dilemma unlike individualized liability-based accounts of the sort developed by McMahan. (shrink)

Recent work in the ethics of war has done much to challenge the collectivism of the convention-based, Walzerian just war theory. In doing so, it raises the question of when it is permissible for soldiers to resort to force. This article considers this issue and, in doing so, argues that the rejection of collectivism in just war should go further still. More specifically, it defends the ‘Individual-Centric Approach’ to the deep morality of war, which asserts that the justifiability of an (...) individual’s contribution to the war, rather than the justifiability of the war more generally, determines the moral acceptability of their participation. It then goes on to present five implications of the Individual-Centric Approach, including for individual liability to attack in war. (shrink)

: When suggesting that we—the affluent in the developed world—are legitimate targets of defensive force due to our contribution to global poverty one is likely to be countered by one of two strategies. The first denies that we contribute to global poverty. The second seems to affirm that we contribute, and even that we have stringent contribution-based duties to address this poverty, but denies that such contribution makes forcible resistance permissible. Those in this second group employ several argumentative strategies. In (...) this paper I investigate these strategies for denying the force-related implication of contribution to poverty. I do not argue for political violence or for the permissibility of targeting the affluent, I merely investigate a conditional: if contribution to global poverty generates stringent duties to address it, then this contribution implies permission on the part of the victims to defend themselves with force, or for third parties to use force on their behalf.

Some contemporary Just War theorists, like Jeff McMahan, have recently built upon an individual right of self-defense to articulate moral rules of war that are at odds with commonly accepted views. For instance, they argue that in principle combatants who fight on the unjust side ought to be liable to punishment on that basis alone. Also, they reject the conclusion that combatants fighting on both sides are morally equal. In this paper, I argue that these theorists overextend their self-defense analysis (...) when it comes to the punishment of unjust combatants, and I show how in an important sense just and unjust combatants are morally equal. I contend that the individualistic and quid pro quo perspective of the self-defense analysis fails to consider properly how the international community, morally speaking, ought to treat combatants, and I set forth four elements of justice applicable to war, which, together, support the conclusion that in principle the international community should not take on the activity of punishing combatants solely for fighting on the unjust side.

The principle of discrimination (or distinction, as it is sometimes called in legal circles) requires that soldiers treat civilians differently from fellow soldiers, generally not attacking the former except in extreme situations. The Geneva Conventions call for a clear separation of people into two camps: those who are protected from assault, including army medical personnel, injured soldiers, prisoners of war, and civilians on the one hand, and soldiers actively engaged in hostilities on the other hand. Since the Middle Ages, it (...) has been common to differentiate these people into two large groups, although there has not been wide agreement about which of the following groups were the most salient: civilians versus soldiers; noncombatants versus combatants; or the innocent versus the non-innocent (the guilty). In this chapter, I will argue that the principle of discrimination or distinction is most plausibly defended as an extension of the principle of humane treatment, and only on that basis is it to be seen as providing a nonutilitarian basis for deciding how to act during war.

The traditional theory of the just war comprises two sets of principles, one governing the resort to war ( jus ad bellum) and the other governing the conduct of war ( jus in bello). The two sets of principles are regarded, in Michael Walzer’s words, as “logically independent. It is perfectly possible for a just war to be fought unjustly and for an unjust war to be fought in strict accordance with the rules.”1 Let us say that those who fight (...) in a just war are “just combatants,” while those who fight in a war that is unjust because it lacks a just cause are “unjust combatants.” (A just cause is an aim that can contribute to the justification for war and that may permissibly be pursued by means of war.)2 The most important implication of the idea that jus in bello is independent of jus ad bellum is that..

This paper argues that certain central tenets of the traditional theory of the just war cannot be correct. It then advances an alternative account grounded in the same considerations of justice that govern self-defense at the individual level. The implications of this account are unorthodox. It implies that, with few exceptions, combatants who fight for an unjust cause act impermissibly when they attack enemy combatants, and that combatants who fight in a just war may, in certain circumstances, legitimately target noncombatants (...) who bear a significant degree of moral responsibility for a wrong, when the prevention or rectification of that wrong constitutes a just cause for war.

This thesis examines the key moral principles that should govern decision-making by police and military when using lethal force. To this end, it provides an ethical analysis of the following question: Under what circumstances, if any, is it morally justified for the agents of state-sanctioned security institutions to use lethal force, in particular the police and the military? Recent literature in this area suggests that modern conflicts involve new and unique features that render conventional ways of thinking about the ethics (...) of armed conflict, and the use of lethal force, as inadequate or redundant. In particular, there is an increased concern with the moral difficulties created by “non-standard” cases. This is where the police or military are obliged to operate outside their conventional contexts. In such non-standard cases, on what moral basis can (or should) state actors – especially the police and military – use lethal force? One approach argues that there is nothing morally exceptional about the use of lethal force by police or military. This says the only available moral justification for using lethal force is killing in self-defence or defence of others. In contrast, I use an institutional approach to develop a moral framework for the state’s morally exceptional use of lethal force. The institutional approach is concerned with the ends (telos) or purpose of a social institution. It says that the moral purpose of a social institution alters the moral responsibilities of its agents; what is referred to as role morality. My analysis demonstrates that there is an important moral distinction between justified killing in self-defence and state-sanctioned uses of lethal force. My claim is that police and military uses of lethal force are not morally justified in the same way as the average person’s use of lethal force (i.e. self-defence or defence of others). Instead, I argue that the state-sanctioned institutional role of police and military give these state actors special moral duties, and therefore exceptional moral justification, for using lethal force. I argue that the institutional end of the police is the preservation of public safety. This includes using lethal force where it is necessary to protect life and prevent serious injury to jurisdictional inhabitants. In contrast, a morally responsible state uses military force to defend the “common good.” That is, when it is necessary to defend the peaceful functioning of a state from armed threats or other forms of political violence. I then conclude that non-standard cases require the addition of jus ad vim (or the just use of military force short-of-war) as a hybrid element to the moral framework for the state-sanctioned use of lethal force. This provides a better way of applying ethics to the use of military force when defending the common good against serious threats in non-standard cases. This is because jus ad vim complements the conventional military paradigm by permitting the use of military capabilities to defend the common good. But, at the same time, it inhibits the move towards the more destructive levels of violence characteristic of conventional warfighting. (shrink)

Most philosophers writing on the ethics of war endorse “reductivist individualism,” a view that holds both that killing in war is subject to the very same principles of ordinary morality ; and that morality concerns individuals and their rights, and does not treat collectives as having any special status. I argue that this commitment to individualism poses problems for this view in the case of national defense. More specifically, I argue that the main strategies for defending individualist approaches to national (...) defense either fail by their own lights or yield deeply counterintuitive implications. I then offer the foundations for a collectivist approach. I argue that such an approach must do justice to the collective goods that properly constituted states make possible and protect through certain acts of defensive war; and that any such picture of national defense must make room for some form of national partiality.

Contemporary just war theory is divided into two broad camps: revisionists and traditionalists. Traditionalists seek to provide moral foundations for something close to current international law, and in particular the laws of armed conflict. Although they propose improvements, they do so cautiously. Revisionists argue that international law is at best a pragmatic fiction—it lacks deeper moral foundations. In this article, I present the contemporary history of analytical just war theory, from the origins of contemporary traditionalist just war theory in Michael (...) Walzer's work to the revisionist critique of Walzer and the subsequent revival of traditionalism. I discuss central questions of methodology, as well as consider the morality of resorting to war and the morality of conduct in war. I show that although the revisionists exposed philosophical shortcomings in Walzer's arguments, their radical conclusions should prompt us not to reject the broad contemporary consensus, but instead to seek better arguments to underpin it.

Recent debates in just war theory have been concerned with the status of combatants during war. Unfortunately, however, the debate has, up to now, focused on self-defensive wars. The present article changes the focus slightly by exploring the status of combatants during military humanitarian intervention (MHI). It begins by arguing that MHI poses a number of challenges to our thinking about the status of combatants. To solve these it draws on Jeff McMahan's theory of combatant liability. On this basis, the (...) article contends that, first, combatants engaged in atrocities lack the same set of rights and liberties held by intervening combatants. Second, and more controversially, drawing on McMahan's theory as well as the notion of complicity, it suggests that the same applies to those combatants who do not perpetrate atrocities but are merely ordered to defend the target state against the intervening state.

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)

Innocence is a notion that can prove controversial. Claims of innocence typically support not imposing burdens on the innocent when their conduct is relevantly unobjectionable. This paper examines innocence in the context of violent conflict between states or groups. Many thinkers about the morality of such violence want to establish a principle that would protect innocent civilians. Yet the common view in just war theory does not affirm the moral innocence of civilians. Similarly, the common view that soldiers have an (...) equal right to kill does not affirm their equal moral culpability. (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.

This paper questions the moral foundations of the equal war-right to kill in international law. Although there seems to be a moral difference between fighting a just and unjust war, this need not reflect on our moral assessment of soldiers, since unjust combatants can be non-culpable by virtue of excuse. Under the aspect of immunity from blame, an equal war-right to kill is upheld, and belligerent equality restored among innocents. It must therefore be proven that innocent threats can be justifiably (...) killed. If this fails, there is nothing about the people who kill and are killed in war that justifies their killing. This leads to a strong presumption against war and to question the notion of just war. Further, there should be an incentive to increase protection of combatants in war. (shrink)

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.

The orthodox account of the morality of war holds that the responsibility for resorting to war rests on the state’s political authorities and the responsibility for how the war is waged rests only on the state’s army and, thus, business firms have no special obligations in wartime. The purpose of this article is to reconsider the ethical responsibilities of business firms in wartime. I defend the claim that a plausible standard of liability in war must integrate the degree of the (...) agent’s contributions to posing an unjust threat, the nature of agent's behavior, and his/her intentions. If these premises are correct, it follows that the moral obligations of civilians and business corporations are fundamentally altered by war. Taking into consideration their relative contributions to the war effort, a taxonomy of business firms is developed. (shrink)

The purpose of this paper is to explore the relation between the right to self-defense against an innocent attacker and the notion of moral luck. It argues that those who accept the existence of such a right rely on the assumption that mere agency makes a significant moral difference – which is precisely the assumption that underlies the view held by believers in moral luck. Those who believe in the right to self-defense against innocent attackers are thus committed to the (...) idea of moral luck much more than they usually acknowledge. The paper also argues that the arguments offered in support of moral luck, in particular the one based on the relation between agency and self-identity, might help to shed light on the rather puzzling above right.
