Interest in just war theory has boomed in recent years, as a revisionist school of thought has challenged the orthodoxy of international law, most famously defended by Michael Walzer [1977]. These revisionist critics have targeted the two central principles governing the conduct of war (jus in bello): combatant equality and noncombatant immunity. The first states that combatants face the same permissions and constraints whether their cause is just or unjust. The second protects noncombatants from intentional attack. In response to these (...) critics, some philosophers have defended aspects of the old orthodoxy on novel grounds. Revisionists counter. As things stand, the prospects for progress are remote. In this paper, we offer a way forward. We argue that exclusive focus on first-order moral principles, such as combatant equality and noncombatant immunity, has led revisionist and orthodox just war theorists to engage in “proxy battles.” Their first-order moral disagreements are at least partly traceable to second-order disagreements about the nature and purpose of political theory. These deeper disputes have been central to the broader discipline of political theory for several years; we hope that bringing them to bear on the ethics of war will help us move beyond the present impasse.

Can the global poor wage a just redistributive war against the global rich? The moral norms governing the use of force are usually considered to be very strict. Nonetheless, some philosophers have recently argued that violating duties of global justicecanbe a just cause for war. This paper discusses redistributive wars. It shows that the strength of these arguments is contingent on the underlying account of global distributive justice. The paper focuses on the “doing harm argument,” under the assumption that the (...) alternative “allowing harm argument” is a more difficult route to justify redistributive wars. After highlighting several preliminary problems, the paper breaks down and assesses in depth the “doing harm argument”: the empirical premise, the rights violation that constitutes the wrong, liability and degrees of responsibility, and the conditions for justified self-defense. By drawing on principles reflected in criminal law, this paper argues that a general “doing harm argument” for redistributive wars is unconvincing, while a reinterpretation of that argument could theoretically give rise to a just cause for war.

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)

This paper argues for the superiority of international law’s existing ban on unilateral secession over its reform to include either a primary or remedial right to secession. I begin by defending the claim that secession is an inherently institutional concept, and that therefore we ought to employ institutional moral reasoning to defend or criticize specific proposals regarding a right to secede. I then respond to the objection that at present we lack the empirical evidence necessary to sustain any specific conclusion (...) regarding an international legal right to secession. Specifically, I argue that we ought to adopt a precautionary approach, and that such an approach justifies giving no weight to promoting political self-determination per se when considering whether to reform international law governing secession. I conclude with several reasons to think that even a remedial right to unilateral secession will detract from, not enhance, the international legal order’s ability to promote peace and human rights.

Through a critical engagement with Jeremy Waldron’s work, as well as the work of other writers, I offer an account of the relative scope of the morality of war, the laws of war, and war crimes. I propose an instrumentalist account of the laws of war, according to which the laws of war should help soldiers conform to the morality of war. The instrumentalist account supports Waldron’s conclusion that the laws of war justifiably prohibit attacks on civilians even if it (...) turns out that some civilians lack a moral right not to be killed. Importantly, the instrumentalist account also offers what Waldron thinks impossible: a non-consequentialist defense of the failure of the laws of war to prohibit the killing of nonthreatening combatants. Finally, I argue that new war crimes can be broader than the morality of war as well as established laws of war and that many of the arguments for defining war crimes more narrowly than either the morality of war or the laws of war are unconvincing. In all of these ways, I hope to carry forward Waldron’s project of exploring the relationship between law and morality in war. (shrink)

The conventional view of Just War thinking holds that militaries operate under “special” moral rules in war. Conventional Just War thinking establishes a principled approach to such moral exceptionalism in order to prevent arbitrary or capricious uses of military force. It relies on the notion that soldiers are instruments of the state, which is a view that has been critiqued by the Revisionist movement. The Revisionist critique rightly puts greater emphasis on the moral agency of individual soldiers: they are not (...) mere instruments of the state. Although Revisionism has something particularly important to contribute when applied to cases that are short-of-war, where an individual agent’s moral culpability plays a greater role, soldiers fighting wars are not wholly autonomous moral agents. An Institutionalist approach that responds to Revisionist criticisms is a plausible alternative to the conventional Just War account for grounding the moral exceptionalism of war. For the Institutionalist, soldiers are moral agents with state-imposed obligations whose fundamental responsibility is the performance of the proper moral ends of the military institution they serve. If this is true, then soldiers have a moral obligation to be attentive to the moral corruption of the military institution of which they are a part. (shrink)

this paper advances a novel account of part of what justifies killing in war, grounded in the duties we owe to our loved ones to protect them from the severe harms with which war threatens them. It discusses the foundations of associative duties, then identifies the sorts of relationships, and the specific duties that they ground, which can be relevant to the ethics of war. It explains how those associa- tive duties can justify killing in theory—in particular how they can (...) justify overrid- ing the rights to life of some of those who must be killed to win a war. It then shows how these duties can be operationalised in practice: first, showing how soldiers who fight on behalf of their community can act on reasons that apply to the members of that community; second, showing that the argument from associative duties does not prove too much—in particular, that it does not license the intentional killing of noncombatants in war.

War should be understood as an actual, intentional and widespread armed conflict between political communities. Thus, fisticuffs between individual persons do not count as a war, nor does a gang fight, nor does a feud on the order of the Hatfields versus the McCoys. War is a phenomenon which occurs only between political communities, defined as those entities which either are states or intend to become states (in order to allow for civil war). Classical war is international war, a war (...) between different states, like the two World Wars. But just as frequent is war within a state between rival groups or communities, like the American Civil War. Certain political pressure groups, like terrorist organizations, might also be considered “political communities,” in that they are associations of people with a political purpose and, indeed, many of them aspire to statehood or to influence the development of statehood in certain lands.

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.

Modern analytical just war theory starts with Michael Walzer's defense of key tenets of the laws of war in his Just and Unjust Wars. Walzer advocates noncombatant immunity, proportionality, and combatant equality: combatants in war must target only combatants; unintentional harms that they inflict on noncombatants must be proportionate to the military objective secured; and combatants who abide by these principles fight permissibly, regardless of their aims. In recent years, the revisionist school of just war theory, led by Jeff McMahan, (...) has radically undermined Walzer's defense of these principles. This essay situates Walzer's and the revisionists’ arguments, before illustrating the disturbing vision of the morality of war that results from revisionist premises. It concludes by showing how broadly Walzerian conclusions can be defended using more reliable foundations. (shrink)

Rights-based approaches and consequentialist approaches to ethics are often seen as being diametrically opposed to one another. In one sense, they are. In another sense, however, they can be reconciled: a ‘global’ form of consequentialism might supply consequentialist foundations for a derivative morality that is non-consequentialist, and perhaps rights-based, in content. By way of case study to illustrate how this might work, I survey what a global consequentialist should think about a recent dispute between Jeff McMahan and Henry Shue on (...) the morality and laws of war.

New biotechnologies have the potential to both dramatically improve human well-being and dramatically widen inequalities in well-being. This paper addresses a question that lies squarely on the fault line of these two claims: When as a matter of justice are societies obligated to include a new biotechnology in a national healthcare system? This question is approached from the standpoint of a twin aim theory of justice, in which social structures, including nation-states, have double-barreled theoretical objectives with regard to human well-being. (...) The first aim is to achieve a sufficient level of well-being in each of six core dimensions. In the special case of healthcare systems, this aim is focally but not exclusively attentive to achieving health sufficiency as one of the core dimensions. The second aim is to combat the emergence and persistence of densely woven patterns of systematic disadvantage that tend to undermine the achievement of a sufficient level of health and the other core elements of well-being of some persons and groups. Judgments about entitlements to health related resources, including new biotechnologies, are made in light of a threshold notion of health sufficiency. What is enough or sufficient health? The answer that is defended here is that sufficient health is enough health for a decent human life, understood as enough health to live a full life course without preventable, significant functional disability or decrement in health, or treatable pain or suffering. When a state must include a new biotechnology in its national healthcare system is also influenced by ancillary concerns about the connection between health and other core dimensions of well-being. What counts as a significant functional impairment or health decrement is thus explicated, in part, in relation to the theory’s sufficiency aim for the other essential dimensions of well-being, and thus for a decent life, overall. Those elements of health that play a critical role in the experience of sufficient reasoning, affiliation, security, respect and self determination are especially important; any loss of health function or capacity that threatens the individual’s prospects for sufficiency in these other dimensions, including the relational egalitiarian concerns they entail, constitutes a significant functional impairment. Within national borders, individuals are thus entitled to those health-related goods and services that are essential for a sufficiency of each of the dimensions of well-being; with regard to self determination and respect, what is sufficient by way of guaranteed access to specific goods and services is going to depend on the implications of such access for where an individual stands in relation to her co-nationals. The content of any entitlement to health-related goods and services is also necessarily dynamic. What can be done for health and the other core dimensions of well-being as a function of technological innovation and diffusion is in constant flux. The paper concludes by considering the implications of this analysis for the conditions under which states are obligated to include access in their healthcare systems to one biotechnology, deep brain stimulation.
