In this article, I present a two-pronged argument for the immorality of contemporary, asymmetric drone warfare, based on my new interpretations of the just war principles of “proportionality” and “moral equivalence of combatants” (MEC). The justification for these new interpretations is that drone warfare continues to this day, having survived despite arguments against it that are based on traditional interpretations of just war theory (including one from Michael Walzer). On the basis of my argument, I echo Harry Van (...) der Linden’s call for “an international treaty banning all weaponized UAV [uninhabited aerial vehicles].”. (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)

May lethal autonomous weapons systems—‘killer robots ’—be used in war? The majority of writers argue against their use, and those who have argued in favour have done so on a consequentialist basis. We defend the moral permissibility of killer robots, but on the basis of the non-aggregative structure of right assumed by Just War theory. This is necessary because the most important argument against killer robots, the responsibility trilemma proposed by Rob Sparrow, makes the same assumptions. We show that (...) the crucial moral question is not one of responsibility. Rather, it is whether the technology can satisfy the requirements of fairness in the re-distribution of risk. Not only is this possible in principle, but some killer robots will actually satisfy these requirements. An implication of our argument is that there is a public responsibility to regulate killer robots ’ design and manufacture. (shrink)

This paper explores the question of whether the United Nations should engage in preventive military actions. Correlatively, it asks whether UN preventive military actions could satisfy just war principles. Rather than from the standpoint of the individual nation state, the ethics of preventive war is discussed from the standpoint of the UN. For the sake of brevity, only the legitimate authority, just cause, last resort, and proportionality principles are considered. Since there has been disagreement about the specific content (...) of these principles, a third question also is explored: How should they be formulated? Moreover, these questions are addressed in the context of a particular issue: the goals of the non-proliferation and the abolition of weapons of mass destruction. (shrink)

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.

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.

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)

I argue that, according to Just War Theory, those who work as administrative personnel in the private military industry can be permissibly harmed while at work by enemy combatants. That is, for better or worse, a Just War theorist should consider all those who work as administrative personnel in the private military industry either: (i) individuals who may be permissibly restrained with lethal force while at work, or (ii) individuals who may be harmed by permissible attacks against their (...) workplace. In doing so, I also provide some critical analysis of the relevant Just War concepts. (shrink)

Quelle est la responsabilité des intellectuels en temps de guerre? Cet article entend offrir une analyse de la pensée de Michael Walzer afin de répondre à cette question. Il s’agira d’abord de revenir sur la distinction classique, au sein des théories de la guerre juste, entre combattants et non combattants. Par la suite, il sera possible d’examiner de manière plus exacte la responsabilité des citoyens en temps de guerre, et plus particulièrement des intellectuels.

The article provides an account of the unlikely revival of the medieval Just War Theory, due in large part to the efforts of Michael Walzer. Its purpose is to address the question: What is a just war theorist? By exploring contrasts between scholarly activity and forms of international activism, the paper argues that just war theorists appear to be just war criminals, both on the count of aiding and abetting aggression and on the count of inciting (...) troops to commit war crimes.

A famous Indian argument for jus ad bellum and jus in bello is presented in literary form in the Mahābhārata: it involves events and dynamics between moral conventionalists (who attempt to abide by ethical theories that give priority to the good) and moral parasites (who attempt to use moral convention as a weapon without any desire to conform to these expectations themselves). In this paper I follow the dialectic of this victimization of the conventionally moral by moral parasites to its (...) philosophical culmination in the fateful battle, which the Bhagavad Gītā precedes. Arjuna’s lament is an internalization of the logic of conventional moral expectations that allowed moral parasitism, and Krishna’s push for a purely procedural approach to moral reasoning (bhakti yoga) does away with the good as a primitive of explanation and provides the moral considerations that allow us to see that the jus ad bellum and jus in bello coincide: the just cause is the approximation to the procedural ideal (the Lord), which is also just conduct. Jeff McMahan is correct in claiming that it is wrong for the unjust to attack the just. But it is also not obviously correct that it is the same set of moral considerations in war and peace that mark out the sides, for peace is largely characterizable by conventional morality, which all are forced to abandon in war. Walzer is correct that there are different sets of standards at play at war and peace, and that getting hands dirty in immorality is a price worth paying in war, but Walzer is thereby incorrect for a subtle reason: conventional standards by way of which jus ad bellum and jus in bello appear corrupt are themselves actually corrupt when the need for a just war arises. It is because moral parasites use conventional morality as a means of hostility and not as a means of fair, inclusive social interaction that conventional morality is corrupted and turned into a tool of the unjust. It is hence unjust to employ these standards to judge those whose cause is just, though such a judgement is conventional. Those who fight for a just cause thereby justly get their hands dirty by departing from conventional moral standards. But this is to the disadvantage of parasites who can only function in a climate where the conventionally good are constrained by conventional morality. Just war so understood deprives parasites their weapon of choice. (shrink)

Vitoria and Suárez defend the categorical immunity of the innocent not to be intentionally killed. But they allow for inflicting collective punishment on the innocent and the noninnocent alike during and after a just war. So they allow for deliberately harming them. Inflicting harm on the innocent can often result in their death. Hence, holding both claims seems incoherent. First, the objections against using the term “innocent” are explained. Second, their views on just war are explored. And third, (...) by appealing to Aquinas' double-effect reasoning, it is shown how they try to avoid the above-mentioned incoherence. Still, their appeal might be insufficient to palliate the tension between the above-mentioned claims. If just wars are possible, the deliberate harming of the innocent is reasonably unavoidable for defeating and punishing those who wage them. Hence, defenders of just wars, whether from a religious or a secular perspective, must live with such a tension. (shrink)

Cicero’s ethical and political writings present a detailed and sophisticated philosophy of just war, namely an account of when armed conflict is morally right or wrong. Several of the philosophical moves or arguments that he makes, such as a critique of “Roman realism” or his incorporation of the ius fetiale—a form of archaic international law—are remarkable similar to those of the contemporary just war philosopher Michael Walzer, even if Walzer is describing inter-state war and Cicero is describing imperial (...) war. But if it is clear that Walzer presents a detailed philosophy of just war, then I argue we should draw the same conclusion for Cicero. The result is a deeper appreciation of the insight and novelty of Cicero’s view of just war. The paper concludes by arguing against the claim that Cicero’s philosophy of just war is derivative from the Stoic philosopher Panaetius, whom Cicero drew upon in the organization of his On Duties. Just as Walzer’s Just and Unjust Wars was written in response to America’s war in Vietnam, Cicero’s just war philosophy was written in response to the wars (both civil and external) of Gaius Caesar.

Analytic just war theorists often attempt to construct ideal theories of military justice on the basis of intuitions about imaginary and sometimes outlandish examples, often taken from non-military contexts. This article argues for a sharp curtailment of this method and defends, instead, an empirically and historically informed approach to the ethical scrutiny of armed conflicts. After critically reviewing general philosophical reasons for being sceptical of the moral-theoretic value of imaginary hypotheticals, the article turns to some of the special problems (...) that this method raises for appraisals of warfare. It examines some of the hypothetical examples employed in the construction of Jeff McMahan’s revisionist just war theory, and finds that they sometimes stipulate incompre- hensible conditions, lead to argumentative impasses of diverging yet uncertain intuitions, and distract attention away from the real problems of war as we empirically know it. In contrast, empirical and historical studies of warfare rein- force the deep connections between facts and values, and compel theorists to face uncomfortable moral ambiguities. Perhaps most importantly, the analytic method of focusing on imaginary hypothetical examples can not only be distracting, but it can also be genuinely dangerous. Hence, the article pays special attention to the way in which a seemingly innocuous fiction like the famous Ticking Time Bomb scenario can come to frame a new paradigm of inhumanity in the treatment of prisoners of war.

The Black Panther Party is now commonly associated with violence; however, this was far from what they aimed to represent. The Party was aimed at total social and political reconstruction and, their larger point, creating an equitable society in which Black Americans could thrive. The criticism which the Party faced (and still faces) was through their use of “armed self-defense” and methods of political violence. From a philosophical perspective, many interesting questions can be considered when evaluating the morality of the (...) utilization of armed self-defense. In this paper, I will use Just War Theory to answer the question: can non-state actors be justified in their usage of violence against states? Specifically, I will claim that the Black Panther Party’s use of armed self-defense and political, physical violence was morally justified under an expanded just war theoretic. To do this, I will first analyze political violence and resistance to clarify how my account will understand the two and their potential overlap. Next, I will clarify Just War Theory and provide thorough discussion of the “competent authority” criterion and argue that select non-state actors can be competent authorities. Finally, I will apply my expanded just war theoretic to the case of the Black Panther Party and their use of armed self-defense. (shrink)

A brief overview of the Christian just war tradition, with case studies.

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)

ABSTRACTThe aim of this paper is to draw attention to an issue which has been largely overlooked in contemporary just war theory – namely the impact that the conditions under which an army is assembled are liable to have on the judgments that are made with respect to traditional principles of jus ad bellum and jus in bello. I argue that the way in which an army is assembled can significantly alter judgments regarding the justice of a war. In (...) doing so, I present and defend a principle of ‘just assembly’ and argue that satisfying this principle is an essential part of any deliberation regarding the justice of a particular conflict.

In a recent article Duncan Purves, Ryan Jenkins, and B. J. Strawser argue that in order for a decision in war to be just, or indeed the decision to resort to war to be just, it must be the case that the decision is made for the right reasons. Furthermore, they argue that this requirement holds regardless of how much good is produced by said action. In this essay I argue that their argument is flawed, in that it (...) mistakes what makes an agent morally good for what makes an act morally good. I argue that the main thrust of Purves et al.’s argument in fact undermines the conclusion they wish to draw, and that the reasons for one’s action do not make an in principle difference to the morality of actions in war. I further argue that this position undermines the traditional ad bellum just war constraint of right intention, and that the morality of actions in war is, at core, only concerned with outcomes. I conclude by clarifying that one’s reasons for action do in fact matter when deciding to enter war or kill in war, but only because one’s reasons significantly impact the way in which one acts. The purpose of this paper is to clear the theoretical space by showing why intentions/reasons do not in principle matter when assessing the morality of war (or killing), but this should not be taken as an argument that we should ignore intentions/reasons altogether.

A fundamental tension exists between Rawls's ideal Kantian conception of justice as fairness (JAF), which requires respecting people as ends, and his realistic non-Kantian consequentialist conception of a supreme emergency in a just war. By justifying the targeting of objectively innocent noncombatants during a supreme emergency exception, Rawls allows for treating them as means only. Hence, his appeal to a supreme emergency is insufficient to avoid this tension. First, since for him JAF is ideal but also practical, one might (...) argue that his fictional people in the original position must reflect on the justification for using force on behalf of JAF. And second, since Rawls justifies targeting objectively innocent people during a supreme emergency exemption, he justifies what one might conceive of as emergency terrorism. Emergency terrorism, however, treats people as means only. Therefore, Rawls's Kantian conception of JAF is in tension with his consequentialist justification of a supreme emergency in a just war and hence with emergency terrorism. (shrink)

The “right intention” requirement, in the form of a requirement that the agent must have a justified true belief that the mind-independent conditions of the justification to use force are fulfilled, is not an additional criterion, but one that constrains the interpretation of the other criteria. Without it, the only possible interpretation of the mind-independent criteria is purely objectivist, that is, purely fact-relative. Pure objectivism condemns self-defense and just war theory to irrelevance since it cannot provide proper action guidance: (...) it is impractically demanding. This means that “revisionist” just war theories which base their doctrine of the moral inequality of combatants on the idea that objective justification defeats liability are irrelevant for the real world, where objective justification is virtually inaccessible. Moreover, only the right intention requirement in the form of a knowledge requirement, as opposed to requiring “good intentions” or “acceptable motivations,” can solve this problem. (shrink)

War is almost always conducted with various restrictions in the form of rules, rituals, and taboos. Many of the norms that regulate warfare can be found in the tradition of just war. This tradition seeks to provide a middle ground between an unrealistic (at least for politicians) pacifism that does not even allow war in self-defence and a too realistic realism that claims there is no place for ethics in war. The tradition of just war does not have (...) the force of law; it provides, above all, a vocabulary to discuss war in moral terms. At the same time, the tradition does have an impact: it forms the basis of humanitarian law and the Geneva Conventions. Just like with laws, it is recognised here that imperfect adherence to these principles does not necessarily diminish their validity. Most proponents of the tradition believe that the principles of just war, even though some date back centuries, are sufficiently general to be applicable to contemporary conflicts, such as the Russo-Ukrainian War. If we apply the norms of the just war tradition to the current situation in Ukraine, we see that Russia is waging an unjust war in an unjust manner. (shrink)

This paper explores Pope Francis’ and the Holy See’s reaction to the war in Ukraine, and attempts to explain the logic behind it. After introducing the Holy See’s statements since the start of Russia’s aggression, the author reads them through the background of Catholic social teaching. In particular, he claims that the ambiguities of the Holy See’s position are due to the unresolved tension between the traditional just war approach and a tendency towards nonviolence. The latter has acquired prominence (...) over the last decades, in particular with Francis’ Fratelli Tutti. The author concludes that the war in Ukraine represents a pivotal moment in the Catholic Church’s thinking on war and peace. (shrink)

Many just war theorists (call them traditionalists) claim that just as people have a right to personal self-defense, so nations have a right to national-defense against an aggressive military invasion. David Rodin claims that the traditionalist is unable to justify most defensive wars against aggression. For most aggressive states only commit conditional aggression in that they threaten to kill or maim the citizens of the nation they are invading only if those citizens resist the occupation. Most wars, then, (...) claimed to be justified by the traditionalist fail to meet the proportionality criterion. Thus, a just war, for Rodin, is best conceived of as a punitive war of law enforcement, not as a war of national-defense. I argue that Rodin does not have a case against the traditionalist. If national-defense is a disproportionate response to conditional aggression, then punitive war is a disproportionate response as well. Furthermore, the belief that punitive war is a proportionate response to conditional aggression underscores the traditionalist’s view that self-determination, cultural identity and the like are of sufficient value to defend by means of lethal force. I end the paper by very briefly sketching an account, different from that of Rodin’s, of how individual nations can be justified in waging wars of law enforcement. (shrink)

Please contact me at [email protected] if you are interested in reading a particular chapter or being sent the entire manuscript for private use. -/- The thesis offers a comprehensive argument in favor of a regulationist approach to autonomous weapon systems (AWS). AWS, defined as all military robots capable of selecting or engaging targets without direct human involvement, are an emerging and potentially deeply transformative military technology subject to very substantial ethical controversy. AWS have both their enthusiasts and their detractors, prominently (...) advocating for a global preemptive ban on AWS development and use. Rejecting both positions, the author outlines a middle-of-the-road regulationist approach that is neither overly restrictive nor overly permissive. The disqualifying flaws of the rival prohibitionist approach are demonstrated in the process. After defining the core term of autonomy in weapon systems, the practical difficulties involved in applying an arms control regime to AWS are analyzed. The analysis shows that AWS are an extremely regulation-resistant technology. This feature when combined with their assumed high military utility makes a ban framework extremely costly to impose and enforce. As such it is ultimately very likely to fail at the benefit of the most unscrupulous international actors and at a very substantial risk to those abiding with international law. Consequently, to be ethically viable, a prohibitionist framework would need to offer substantial moral benefits impossible to attain through the rival regulationist approach. The remainder of the thesis undertakes to demonstrate that this is not the case. Comparing the considerations of military and strategic necessity to humanitarian concerns most commonly voiced by prohibitionists requires finding a common denominator for all values being referred to. Consequently, the thesis proceeds to show that both kinds of concerns are ultimately reducible to respect for basic human rights of all stakeholders, and so that the prohibitionist and regulationist approach may ultimately be compared in terms of consequences their adoption would generate for basic human rights realization. The author then evaluates both the potential humanitarian benefits, and the potential humanitarian hazards of AWS introduction. The benefits of leaving frontline combat to machines are outlined, with the unique kinds of suffering that would be abolished by such a development being described in detail. The arguments against AWS adoption are then divided into three classes: arguments related to alleged impossibility of compliance with The Laws of Armed Conflict, non-consequentialist and broad consequentialist arguments. This analysis, which comprises the greater part of the entire thesis, shows that the concerns behind compliance arguments are indeed substantial and have to be accommodated via a complex framework of best practices, regulations and localized restrictions on some kinds of AWS or AWS use in particular environments. They do not, however, justify a universal ban on using all the diverse forms of AWS in all environments. Non-consequentialist objections are found either reducible to other classes of arguments or thoroughly unconvincing, sometimes to the point of being actually vacuous. Broad consequentialist concerns are likewise found to be accommodable by regulation, empirically unfounded or causally disconnected from the actions of legitimate actors acquiring AWS, and therefore irrelevant to the moral permissibility of such actions. The author concludes that the proponents of prohibitionism are unable to point to moral benefits substantial enough to justify the costs and risks inherent in the approach. A global ban is, in fact, likely to have a worse humanitarian impact that well-regulated AWS adoption even if the strategic risks are disregarded. On the other hand, the analysis shows that there indeed exists an urgent need to regulate AWS through a variety of technological, procedural and legal solutions. These include, but are not limited to, a temporary moratorium on anti-personnel AWS use, development of internationally verified compliance software and eventual legal requirement of its employment, a temporary moratorium on AWS proliferation to state actors and a ban on their proliferation to non-state agents.

Scholarly critiques of the just war tradition have grown in number and sophistication in recent years to the point that available publications now provide the basis for a more philosophically challenging Peace Studies course. Focusing on just a few works published in the past several years, this review explores how professional philosophers are reclaiming the terrain long dominated by the approach of political scientist Michael Walzer. On center stage are British philosopher David Rodin’s critique of the self-defensejustification for (...) war and American philosopher Andrew Fiala’s skeptical assessment of the just war tradition in its entirety. Also considered is a collection of more narrowly focused critiques by philosophers and some highly relevant extra-philosophical studies regarding the social interconnections between authority and violence.

Troubled times often gives rise to great art that reflects those troubles. So too with political theory. The greatest work of twentieth century political theory, John Rawls's A theory of justice, was inspired in various respects by extreme social and economic inequality, racialized slavery and racial segregation in the United States. Arguably the most influential work of political theory since Rawls—Michael Walzer's Just and unjust wars—a sustained and historically informed reflection on the morality of interstate armed conflict—was written in (...) the midst of the Vietnam War. It should be no surprise, then, that the bellicose period of the past 20 years should give rise to a robust new literature in political theory on the morality of armed conflict. It has been of uneven quality, and to some extent episodic, responding to particular challenges—the increased prevalence of asymmetric warfare and the permissibility of preventive or preemptive war—that have arisen as a result of specific events. In the past decade, however, a group of philosophers has begun to pose more fundamental questions about the reigning theory of the morality of armed conflict warfare—just war theory—as formulated by Walzer and others. Jeff McMahan's concise, inventive and tightly argued work Killing in war is without doubt the most important of these challenges to the reigning theory of the just war. This review article discusses McMahan's work, some of the critical attention it has received, and its potential implications for practice. (shrink)

In War & Ethics, Nicholas Fotion undertakes three main tasks. The first is critical: to analyze ‘Just War Theory’ (JWT) in the evolving context of modern warfare between nations and non-nation groups, using various case studies to illustrate the strengths and weaknesses of the theory.

The third and final task is defensive: to (...) show that Just War Theory in general, and the twin theory in particular, are useful tools in assessing when a war is just. (shrink)

Reply to commentators: Symposium on the winner of the 2019 NASSP Book Award Prize: Yvonne Chiu, *Conspiring with the Enemy: The Ethic of Cooperation in Warfare* (Columbia University Press, 2019).

I critically examine the South African university student and worker protests of 2015/2016 in light of moral principles governing the use of force that are largely uncontested in both the contemporary Western and African philosophies of just war, violence and threats. Amongst these principles are: “discrimination”, according to which force should be directed not towards innocent bystanders but instead should target those particularly responsible for injustice; “likely success”, meaning that, instead of being counter-productive, the use of force must be (...) reasonably expected to advance a just cause; and “last resort”, which entails that only the least force necessary to rebut injustice should be employed. I invoke these and related principles to appraise a wide array of types of student/worker protests, noting which of them accorded with the principles and which did not. I also reply to defences that some South Africans have recently made of protesting with coercion and destruction. (shrink)

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)

This dissertation aims to look at the moral justification for war in a critical way so that we can better understand both the justice and morality of war. In contrast to natural disasters, war has historically been viewed as an extreme manifestation of human social failure. The vast majority of theorists who address the morality of war do so within the moral framework established by Just War Theory; a normative account of war that dates all the way back to (...) the Western Philosophical Tradition over 1500 years. Recent events in the conduct of wars around the world, however, have called into question the just war theory's relevance and applicability to contemporary wars. For instance, morality and virtue have had no place in society during recent wars. This work will examine several major theorists in the history of Western Just War Theory (St Thomas Aquinas and Augustine), demonstrating that the forefathers of Just War Theory did regard moral virtues and ethical principles as central to the morality of war. I will critically examine the concept of a just war through a discussion of various formulations of the realist and pacifist positions and argue that, while the just war tradition offers a reasonable alternative to either of these extremes, its glaring shortcomings (the theory's inability to address the rise of non-state actors such as al-Qaeda, the increasing availability of weapons of mass destruction, etc) should not be overlooked. Finally, I will argue that the theory of just war is obsolete, impractical, unrealistic, and flawed in the modern era, particularly if one wishes to maintain a moral constraint on war. (shrink)

This article asks whether a country that suffers from serious environmental problems caused by another country could have a just cause for a defensive war? Danish philosopher Kasper Lippert-Rasmussen has argued that under certain conditions extreme poverty may give a just cause for a country to defensive war, if that poverty is caused by other countries. This raises the question whether the victims of environmental damages could also have a similar right to self-defense. Although the article concerns justice (...) of war, we will concentrate only on the issue of what can be just causes of war, instead of evaluating the entire justification of war. This is to say that we will limit our discussion to the question concerning just cause and leave aside more general questions concerning justness and moral permissibility of war. Our aim is to list the questions that must be made and settled if defensive war in the case of serious environmental problems is said to have (or not to have) a just cause. We will argue that there are three questions that are most important in this context. They are the question concerning liability, the question of collective responsibility, and the question whether environmental harms may create a “sufficient reason” for raising a war. (shrink)

In this chapter, I add to the new body of philosophical literature that addresses African approaches to just war by reflecting on some topics that have yet to be considered and by advancing different perspectives. My approach is two-fold. First, I spell out a foundational African ethic, according to which one must treat people’s capacity to relate communally with respect. Second, I derive principles from it to govern the use of force and violence, and compare and contrast their implications (...) for war with other recent African views and especially with some prominent accounts in contemporary Anglo-American philosophy. I argue that the approaches to military conflict prescribed by the Afro-communal ethic and its derivative principles differ, and in some prima facie plausible ways, from the views of thinkers that include Thomas Hurka, David Luban, Larry May, Jeff McMahan, and Michael Walzer. In particular, I conclude that the African perspectives ground some interesting and under-explored approaches to just causes for war that merit consideration, including the ideas that military conflict could in principle be justified in order to protect a people’s culture or to correct an aggressor’s vice.

Just war theory is currently dominated by two positions. According to the orthodox view, provided that jus in bello principles are respected, combatants have an equal right to fight, regardless of the justice of the cause pursued by their state. According to “revisionists” whenever combatants lack reasons to believe that the war they are ordered to fight is just, their duty is to disobey. I argue that when members of a legitimate state acting in good faith are ordered (...) to fight, they acquire a pro-tanto obligation to obey which does not depend for its validity on the justice of the cause being pursued. However, when the war is unjust, this obligation may be overridden, under certain conditions, by the obligation not to contribute to the unjustified killing of innocents. This is because the pro-tanto force of the duty to obey the law is best understood in terms of “presumptive”, rather than “exclusionary” reasons for action. This approach captures the insights of both the orthodox and the revisionist view, while avoiding the problems that afflict each of them. (shrink)

Just War Theory (JWT) replaced an older "warrior code," an approach to war that remains poorly understood and dismissively treated in the philosophical literature. This paper builds on recent work on honor to address these deficiencies. By providing a clear, systematic exposition of "Honor War Theory" (HWT), we can make sense of paradigm instances of warrior psychology and behavior, and understand the warrior code as the martial expression of a broader honor-based ethos that conceives of obligation in terms of (...) fair competition for prestige. Far from being a romantic and outmoded approach to war, HWT accounts for current conflicts and predicts moral intuitions that JWT either rejects or cannot comfortably accommodate. So although it is not recommended as a replacement for JWT, there is good reason think that a fully mature, realistic, and yet properly normative theory of war ethics will incorporate a variety of insights from HWT.

In this chapter, I argue that the notion which Michael Walzer calls jus ad vim might improve the moral evaluation for using military lethal force in conflicts other than war, particularly those situations of conflict short-of-war. First, I describe his suggested approach to morally justifying the use of lethal force outside the context of war. I argue that Walzer’s jus ad vim is a broad concept that encapsulates a state’s mechanisms for exercising power short-of-war. I focus on his more narrow (...) use of jus ad vim which is the state’s use of lethal force. Next I address Tony Coady’s critique of jus ad vim. I argue that Coady highlights some important problems with jus ad vim, but these concerns are not sufficient to dismiss it completely. Then, in the final section, I argue that jus ad vim provides an appropriate “hybrid” moral framework for judging the ethical decision-making outside of war by complementing other conventional just war distinctions. A benefit of jus ad vim is that it stops us expanding the definition of war while still providing the necessary ethical framework for examining violent conflict outside that context. (shrink)

In international law and just war theory, war is treated as normatively and legally unique. In the context of international law, war’s special status gives rise to a specific set of belligerent rights and duties, as well as a complex set of laws related to, among other things, the status of civilians, prisoners of war, trade and economic relationships, and humanitarian aid. In particular, belligerents are permitted to derogate from certain human rights obligations and to use lethal force in (...) a far more permissive manner than is the case in other kinds of conflicts and in domestic law enforcement operations. Given war’s unique status, the task of defining war requires not just identifying the empirical features that are characteristic of war but explaining and justifying war’s special legal and moral status. In this chapter, I propose a definition of war that captures war’s unique features and can offer insights into when and how some forms of unarmed conflict could count as wars. (shrink)

Just war theory − as advanced by Michael Walzer, among others − fails to take war seriously enough. This is because it proposes that we regulate war with systematic rules that are comparable to those of a game. Three types of claims are advanced. The first is phenomenological: that the theory's abstract nature interferes with our judgment of what is, and should be, going on. The second is meta-ethical: that the theory's rules are not, in fact, systematic after all, (...) there being inherent contradictions between them. And the third is practical: that by getting people to view war as like a game, the theory promotes its ‘aestheticization’ (play being a central mode of the aesthetic) such that those who fight are encouraged to act in dangerous ways. And war, it goes without saying, is already dangerous enough. (shrink)

I argue that the lives of domestic and enemy civilians should not receive equal weight in our proportionality calculations. Rather, the lives of enemy civilians ought to be “partially discounted” relative to the lives of domestic civilians. We ought to partially discount the lives of enemy civilians for the following reason (or so I argue). When our military wages a just war, we as civilians vest our right to self-defense in our military. This permits our military to weigh our (...) lives more heavily. Before arguing for this view I first explain why recent accounts attempting to show the opposite – that enemy civilians ought to be weighed more heavily – are mistaken. (shrink)

I argue that the criterion of just cause is not independent of proportionality and other valid jus ad bellum criteria. One cannot know whether there is a just cause without knowing whether the other (valid) criteria (apart from ‘right intention’) are satisfied. The advantage of this account is that it is applicable to all wars, even to wars where nobody will be killed or where the enemy has not committed a rights violation but can be justifiably warred against (...) anyway. This account also avoids the inefficiency of having proportionality considerations come up at two different points: in a separate criterion of just cause and in the criterion of proportionality proper. ‘Right intention’, the subjective element of the justification of a war, on the other hand, is not to be subsumed under the criterion of just cause: there can be a just cause without anybody knowing it. Conversely, however, the subjective element requires that those responsible for waging the war do know that the justifying objective conditions are fulfilled. This is in one sense more demanding than traditional just war theory; in another sense, however, it is less demanding: nobody needs to intend to fight for a ‘just aim’. (shrink)

Even in just wars we infringe the rights of countless civilians whose ruination enables us to protect our own rights. These civilians are owed compensation, even in cases where the collateral harms they suffer satisfy the proportionality constraint. I argue that those who authorize or commit the infringements and who also benefit from those harms will bear that compensatory duty, even if the unjust aggressor cannot or will not discharge that duty. I argue further that if we suspect antecedently (...) that we will culpably refrain from compensating those victims post bellum, then this makes satisfying the war’s proportionality constraint substantially more difficult at the outset of the war. The lesson here is that failing to take duties of compensation in war seriously constrains our moral permission to protect ourselves. (shrink)

The vast majority of work on the ethics of war focuses on traditional wars between states. In this chapter, I aim to show that this is an oversight worth rectifying. My strategy will be largely comparative, assessing whether certain claims often defended in discussions of interstate wars stand up in the context of civil conflicts, and whether there are principled moral differences between the two types of case. Firstly, I argue that thinking about intrastate wars can help us make progress (...) on important theoretical debates in recent just war theory. Secondly, I consider whether certain kinds of civil wars are subject to a more demanding standard of just cause, compared to interstate wars of national-defence. Finally, I assess the extent to which having popular support is an independent requirement of permissible war, and whether this renders insurgencies harder to justify than wars fought by functioning states.

Despite recent growth in surveillance capabilities there has been little discussion regarding the ethics of surveillance. Much of the research that has been carried out has tended to lack a coherent structure or fails to address key concerns. I argue that the just war tradition should be used as an ethical framework which is applicable to surveillance, providing the questions which should be asked of any surveillance operation. In this manner, when considering whether to employ surveillance, one should take (...) into account the reason for the surveillance, the authority of the surveillant, whether or not there has been a declaration of intent, whether surveillance is an act of last resort, what is the likelihood of success of the operation and whether surveillance is a proportionate response. Once underway, the methods of surveillance should be proportionate to the occasion and seek to target appropriate people while limiting surveillance of those deemed inappropriate. By drawing on the just war tradition, ethical questions regarding surveillance can draw on a long and considered discourse while gaining a framework which, I argue, raises all the key concerns and misses none.

I address a foundational problem with accounts of the morality of war that are derived from the Just War Tradition. Such accounts problematically focus on ‘the moment of crisis’: i.e. when a state is considering a resort to war. This is problematic because sometimes the state considering the resort to war is partly responsible for wrongly creating the conditions in which the resort to war becomes necessary. By ignoring this possibility, JWT effectively ignores, in its moral evaluation of wars, (...) certain types of past wrongdoing. I argue that we can address this problem by incorporating an account of compensatory liability into an account of the morality of war. Doing so yields the view that, if we have culpably failed to compensate victims for past wrongs, we might be morally required to weigh the well-being of those victims more heavily in our calculation of proportionality when determining the permissibility of a defensive act that harms the victim as a side-effect. This, in turn, makes satisfying t. (shrink)
