This paper reflects on the current war on Gaza in 2024 that followed the Hamas attack on October 7th 2023, reading the events is a wider historical context. The paper has three main parts. In the first part, the paper argues against the fragmentation of the question of Palestine historically and geographically, arguing instead for the importance of the overall context of the conflict. The second part considers the issue of Palestinian resistance. How can the Palestinians resist occupation? This part (...) is mainly descriptive and indicates the impasse that the Palestinians found themselves in it after the Oslo accords in 1993. The third and last part moves to normative questions regarding the question of self-defense both on the part of the Palestinians and on the part of Israel and tries to outline the ways these arguments can develop.

This article argues that the reduction of the morality of killing in war to the morality of killing in self-defense by ‘reductive-individualist’ revisionist just war theories is inconsistent, because when those theories apply the moral notion of self-defense to the morality of killing in war, they do not preserve the two conceptions of the “individual” inherent in this notion. The article demonstrates this inconsistency in two steps: First, it disentangles the two conceptions of the individual inherent to the notion of (...) self-defense, namely (1) that the individual is an “entity” potentially bearing a right to self-defense (unlike, e.g., groups) and (2) that the individual is a “particular,” where “particular” signifies that every human is different from every other human. The conception of the individual as a “particular” is tied to the idea that a justification grounded in a rule of self-defense is necessarily “concrete,” in the sense of referring to individually given and specific perceptions or cases, as opposed to “abstract,” in the sense of being detached from specific perceptions or cases. The article then demonstrates that reductive individualism reflects the first notion of the individual, but not the second. Due to the “loss” of the individual as a “particular”, the reductive-individualist reduction of the morality of killing in war to the morality of killing in self-defense is inconsistent, and hence its justification of killing in war grounded in self-defense is not concrete. Since such a justification must be concrete, reductive individualism cannot offer a justification for belligerent killing. (shrink)

It is common in moral philosophy to test the validity of moral principles by proposing counter-examples in the form of cases where the application of the principle does not give the conclusion we intuitively find valid. These cases are often imaginary and sometimes rather ‘outlandish’, involving ray guns, non-existent creatures, etc. I discuss whether we can test moral principles with the help of outlandish cases, or if only realistic cases are admissible. I consider two types of argument against outlandish cases: (...) 1) Since moral principles are meant for guiding action in this world, cases drawn from other worlds are irrelevant. 2) We lack the capacity to apply our intuitive moral competence to outlandish cases. I argue that while the first approach is importantly flawed, the second approach is plausible, not because our moral competence per se is limited to cases from this world, but because we lack the capacity to imagine outlandish cases, and we cannot apply our moral competence to a case we fail to imagine properly.

In this paper I focus on duties we owe refugees from conflict zones. I argue that it is important to distinguish between two types of duties one might have with respect to refugees from conflict zones. Belligerents from wars that resulted in excess numbers of refugees, I argue, have a stringent duty to remedy past harms and provide for resulting refugees. Other states have a duty to aid which is context-dependent and can be in some cases as stringent as the (...) duty to remedy past harms. I argue that making a distinction between the grounds and types of duties different actors have with respect to refugees from conflict zones has significant consequences both for just war theory, but also for practical questions about how best to discharge our duties to refugees from conflict zones.

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)

ABSTRACTThis article provides a normative appraisal of the law of military occupation by looking into occupation courts and their legitimacy. It focuses on two cornerstones of the current regulation of war: the principle of equality of belligerents, that is, the potential relevance ofjus ad bellumconsiderations on thein bellorights of occupants, and the normative force of the traditional distinction between states and non-state armed groups, specially in conflicts not of an international character. Against the currently predominant neoclassical position in just war (...) theory, it argues in favor of the moral equality of just and unjust occupants. Against the orthodox position in international law, it advocates the symmetrical treatment of states and non-state actors fighting internal armed conflicts, at least in terms of the rights they may claim on the territories under their control. It concludes by appraising the way in which this moral landscape should be translated into legal norms. (shrink)

The article critically analyzes one of the central assumptions of Michael Walzer’s version of just war theory, as presented in his main work devoted to war ethics. As requested by the author of Just and Unjust Wars, the controversial nature of the principle of the moral equality of soldiers is revealed by discussing the actual course of events of a historical military conflict – namely, the outbreak of World War II, one of the main issues dealt with in Walzer’s book. (...) The exclusion of individual responsibility of people involved in a military operation which finds no moral justification seems to entail a number of consequences that put a heavy burden on Walzer’s overall model of military ethics. In order to ensure the necessary level of coherence of just war theory one may need to modify Walzer’s principle of the moral equality of soldiers – at least in relation to the participants of total war.

The Moral Responsibility Account of Liability to Defensive Harm (MRA) states that an agent becomes liable to defensive harm if, and only if, she engages in a foreseeably risk-imposing activity that subsequently threatens objectively unjustified harm. Advocates of the account contend that liability to defensive harm is best understood as an aspect of distributive justice. Individuals who are liable to some harm are not wronged if the harm is imposed on them, and liability to defensive harm thus helps ensure that (...) harm is borne by whoever has least of an objection of justice against being burdened with it—or so advocates of the MRA insist. In this paper, I argue that liability to defensive harm is not grounded in considerations of distributive justice. While it depends on the wider societal context what allocation of a burden is distributively most just, liability to defensive harm is a distinctly localised affair. I propose that liability to defensive harm is best understood as part of the enforcement dimension of our rights to non-interference. Framing liability in this way does not invalidate the MRA. It does, however, render subjective impermissibility accounts of liability particularly promising. (shrink)

In his book, A Theory of Truces, Nir Eisikovits offers a perceptive and timely ethics of truces based on the claim that we need to reject the ‘false dichotomy between the ideas of war and peace’ underpinning much current thought about conflict and conflict resolution. In this article, I concur that truces and ‘truce thinking’ should be a focus of concern for any political theory wishing to address the realities of war. However, Eisikovits’s account, to be convincing, requires engagement with (...) a tradition of thought figuring only marginally in his reflections on truces, that is, just war theory. I argue this for three reasons. Without incorporation of the just war principles that should inform the decisions to enter conflict, to maintain conflict, and to cease conflict, any theory of truces will be, first, normatively inadequate, failing to provide us with requisite direction, and, second, open to the charge of permitting intolerable injustices, a charge Eisikovits wishes to avoid. Third, engagement with just war theory is important for arriving at a nuanced understanding of peacemaking, one which grants truces their place in our deliberations and spurns simplistic ‘war versus peace’ binaries whilst keeping more ambitious ideals of peace firmly in sight.

Contemporary just war thinking has mostly been split into two competing camps, namely, Michael Walzer’s approach and its revisionist critics. While Walzerians employ a casuistical method, most revisionists resort to analytical philosophy’s reflective equilibrium. Importantly, besides employing different methods, the two sides also disagree on substantive issues. This article focuses on one such issue, the moral equality of combatants, arguing that while a methodological reconciliation between the two camps is impossible, contemporary debate would benefit from a ‘third-way’ approach. Presenting James (...) Turner Johnson’s historical method as such an approach, the article suggests that while revisionists are correct in considering the symmetry thesis as ethically indefensible, in order to arrive at this judgement, it is not necessary to employ far-fetched thought experiments and the use of historical cases is preferable. The root cause of Walzer’s problematic reasoning vis-à-vis the symmetry thesis, the histori... (shrink)

In June of 1945, the International Military Tribunal (ITM) formed in London, faced the problem of a non-yet existing legal armor for the Nazi crimes. Two new rules were widely accepted there. First, a new category of war crimes, the “crimes against humanity” was legally defined. Second, the ex-ante rejection of the defense line “I was following orders” or Führerprinzip (the principle of the duty to obey every order given by the military leader). In the first part of this paper, (...) I will present in brief, the historical and legal context of the rejection of Führerprinzip as a defense line of the Nazi defendants in Nuremberg trials as also in Eichmann’s trial in Jerusalem, where the same legal context was enacted. Next, I will expose a short history of conscientious objection in war ethics and the International Law on Human Rights that supports it. This exposition reveals that objection to criminal orders has the status not only of a right, but also of a duty for the soldiers on either side of the war. In the third part, the Rawlsian view on conscientious objector will be exposed as the meeting point of a broadly Kantian conception of war ethics and the existing International Law frame. In the final part I will present some philosophical aspects of jus in bello theory, as also the critique of its importance, and its contribution to the reification of the moral importance of conscientious objection in wartime and the rejection of Führerprinzip.

My claim is that despite powerful arguments to the contrary, a coherent moral distinction between the jus in bello code and the jus ad bellum code can be sustained. In particular, I defend the traditional just war doctrine according to which the independence between the in bello and ad bellum codes reflects the moral equality between just and unjust combatants and between just and unjust non-combatants. In order to establish this, I construe an in bello proportionality condition which can be (...) satisfied by just and unjust combatants alike. (shrink)

According to the purist war ethic, the killings committed by soldiers fighting in just wars are permissible, but those committed by unjust combatants are nothing but murders. Jeff McMahan asserts that purism is a direct consequence of the justice-based account of self-defence. I argue that this is incorrect: the justice-based conception entails that in many typical cases, killing unjust combatants is morally unjustified. So real purism is much closer to pacifism than its proponents would like it to be. I conclude (...) that the best explanation of the common view that unjust combatants may be defensively killed relies on a rights-based conception of self-defence. (shrink)

Civilian Immunity is the legal and moral protection that civilians enjoy against the effects of hostilities under the laws of armed conflict and according to the ethics of killing in war. Immunity specifies different permissibility conditions for directly targeting civilians on the one hand, and for harming civilians incidentally on the other hand. Immunity is standardly defended by appeal to the Doctrine of Double Effect. We show that Immunity's prohibitive stance towards targeting civilians directly, and its more permissive stance towards (...) harming them incidentally, can be defended without appealing to the DDE if agents suffer from overconfidence. Overconfidence is a cognitive bias that affects agents who are required to make decisions in the presence of significant uncertainty. (shrink)

Revisionist just war theorists maintain that, soldiers, and not merely their leaders or superiors, bear moral responsibility for objectively wrongful harms imposed in pursuit of an unjust war. The conviction that underlies revisionism is that a person's responsibility for her intentional, objectively unjustified, killing is non-transferable. In this essay I aim to elaborate a specific counterexample to this general claim. I will argue that in cases that I characterize as "special authority cases", the moral responsibility for the unintended outcomes that (...) a person brings about because of following the orders of a legitimate authority is transferred to the authority.

One motivation for adopting a justice-based view of the right to self-defense is that it seems to solve the puzzle of how a victim may kill her attacker even when doing so is not predicted to protect her from the threat imposed upon her. The paper shows (a) that this view leads to unacceptable results and (b) that its solution to cases of futile self-defense is unsatisfactory. This failure makes the interest-based theory of self-defense look more attractive, both in the (...) context of futile self-defense and in general. To understand how a victim might use force in this context, one need only point to some interest of hers that is threatened, and the best candidate for such interest in cases of futile self-defense is her honor.

Section 3 details the systematization of Just War theory in Aquinas and his successors, especially Vitoria, Sua´rez, and Grotius. Section 4 examines the emergence of Perpetual Peace theory after Hobbes, focusing in particular on Rousseau and Kant. Finally, Section 5 outlines the central points of contention following the reemergence of Just War theory (...) in the 1970s. (shrink)

This paper surveys the most important recent debates within the ethics of war. Sections 2 and 3 examine the principles governing the resort to war (jus ad bellum) and the principles governing conduct in war (jus in bello). In Section 4, we turn to the moral guidelines governing the ending and aftermath of war (jus post bellum). Finally, in Section 5 we look at recent debates on whether the jus ad bellum and the jus in bello can be evaluated independently (...) of each other. (shrink)

Common sense suggests that if a war is unjust, then there is a strong moral reason not to contribute to it. I argue that this presumption is mistaken. It can be permissible to contribute to an unjust war because, in general, whether it is permissible to perform an act often depends on the alternatives available to the actor. The relevant alternatives available to a government waging a war differ systematically from the relevant alternatives available to individuals in a position to (...) contribute to the war. Hence the conditions determining whether it is permissible for a government to wage a war often differ from the conditions determining whether it is permissible for others to promote that war. This difference is manifest most often in unjust wars with putatively humanitarian aims—an increasingly common type of war. (shrink)

Political theorists had vigorous debates about nuclear weapons in the 1980s but have been largely silent about them recently. This article seeks to reopen those discussions. It evaluates the main justifications for nuclear proliferation since 1945: arguments from consistency, nationalism, democratic legitimacy, self-defense, peaceful effects, and supreme emergency. Most of these arguments are badly flawed, as are the arguments for retaining the nuclear arsenals of many of the established nuclear powers. Instead, this article proposes a first cut at a stringent (...) standard for judging the acquisition of strategic nuclear weapons, drawing on jus ad bellum and jus in bello principles. (shrink)

The paper examines the justification of warfare. The main thesis is that war is very difficult to justify, and justification by invoking “justice” is not the way to succeed it. Justification and justness are very different venues: while the first attempts to explain the nature of war and offer possible schemes of resolution, the second aims to endorse a specific type of warfare as correct and hence allowed – which is the crucial part of “just war theory.” However, “just war (...) theory,” somewhat Manichean in its nature, has very deep flaws. Its final result is criminalization of war, which reduces warfare to police action, and finally implies a very strange proviso that one side has a right to win. All that endangers the distinction between ius ad bellum and ius in bello, and destroys the collective character of warfare. Justification of war is actually quite different – it starts from the definition of war as a kind of conflict which cannot be solved peacefully, but for which there is mutual understanding that it cannot remain unresolved. The aim of war is not justice, but peace, i.e. either a new articulation of peace, or a restoration of the status quo ante. Additionally, unlike police actions, the result of war cannot be known or assumed in advance, giving war its main feature: the lack of control over the future. Control over the future, predictability, is a feature of peace. This might imply that war is a consequence of failed peace, or inability to maintain peace. The explanation of this inability forms the justification of war. Justice is always an important part of it, but justification cannot be reduced to it. The logic contained here refers to ius ad bellum, while ius in bello is relative to various parameters of sensitivity prevalent in a particular time, with the purpose to make warfare more humane and less expensive.

The present paper is devoted to a detailed presentation of a new Military Ethics doctrine of fighting terror. It is proposed as an extension of the classical Just War Theory, which has been meant to apply to ordinary international conflicts. Since the conditions of a fight against terror are essentially different from the conditions that are assumed to hold in the classical war (military) paradigm or in the law enforcement (police) paradigm, a third model is needed. The paper proposes such (...) a model in the form of principles that should govern the activity of a democratic state when faced with terror. Eleven principle are proposed. Two are on the level of the state, including the Principle of Self-Defense Duty. Six are related to military preventive acts against activities of terror, including new formulations of a Principle of Military Necessity, a Principle of Distinction, and a Principle of Military Proportionality. Principles of Low Probabilities, Time Span Considerations and Professional Understanding are also included. Finally, three principles that are related to consciousness-directed activities against terror are added: a Principle of Permanent Notice, a Principle of Compensation, and a Principle of Operational Deterrence. The exposition of the principles is accompanied by arguments about their moral justification. The doctrine has been developed on the background of the IDF fight against acts and activities of terror performed by Palestinian individuals and organizations. (shrink)

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)

While nothing justifies atrocity, many perpetrators manifest cognitive impairments that profoundly degrade their capacity for moral judgment, and such impairments, we shall argue, preclude the attribution of moral responsibility.

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.

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.

What proper role should considerations of risk, particularly to research subjects, play when it comes to conducting research on human enhancement in the military context? We introduce the currently visible military enhancement techniques (1) and the standard discussion of risk for these (2), in particular what we refer to as the ‘Assumption’, which states that the demands for risk-avoidance are higher for enhancement than for therapy. We challenge the Assumption through the introduction of three categories of enhancements (3): therapeutic, preventive, (...) and pure enhancements. This demands a revision of the Assumption (4), alongside which we propose some further general principles bearing on how to balance risks and benefits in the context of military enhancement research. We identify a particular type of therapeutic enhancements as providing a more responsible path to human trials of the relevant interventions than pure enhancement applications. Finally, we discuss some possible objections to our line of thought (5). While acknowledging their potential insights, we ultimately find them to be unpersuasive, at least provided that our proposal is understood as fully non-coercive towards the candidates for such therapeutic enhancement trials.

This book sheds light on various ethical challenges military and humanitarian health care personnel face while working in adverse conditions. Contexts of armed conflict, hybrid wars or other forms of violence short of war, as well as natural disasters, all have in common that ordinary circumstances can no longer be taken for granted. Hence, the provision of health care has to adapt, for example, to a different level of risk, to scarce resources, or uncommon approaches due to external incentives or (...) requirements. This affects the practice of health care as well as its ethics. This book offers a panoramic overview on various challenges healthcare faces in extraordinary situations and provides new insights from practitioners’ as well as from academic scholars’ perspectives.

Just War Theory debates discussing the principle of the Moral Equality of Combatants involve the notion of Invincible Ignorance; the claim that warfi ghters are morally excused for participating in an unjust war because of their epistemic limitations. Conditions of military deployment may indeed lead to genuinely insurmountable epistemic limitations. In other cases, these may be overcome. This paper provides a preliminary sketch of heuristics designed to allow a combatant to judge whether or not his war is just. It delineates (...) the sets of relevant facts uncontroversially accessible and inaccessible to contemporary professional soldiers. Relevant facts outside these two sets should by default be treated as inaccessible until proven otherwise. Even such a rudimentary heuristic created in this way demonstrates that practical recommendations of MEC-renouncing Just War Theory are not too challenging to follow and still signifi cantly impact a compliant combatant’s behavior.

Contra Michael Walzer and Jeff McMahan, neither classical just war theory nor the contemporary rules of war require or support any notion of combatant moral equality. Nations rightly accept prohibitions against punishing enemy combatants without recognizing any legal or moral right of aggressors to kill. The notion of combatant moral equality has real import only in our interpersonal -- and intrapersonal -- attitudes, since the notion effectively preempts any ground for conscientious objection. Walzer is criticized for over-emphasizing our collective responses (...) to war conduct and slighting our personal, extra-political responses. (shrink)

Two conditions guiding permissible use of force in self-defence are proportionality and success.

Yitzhak Benbaji argues that those combatants who have agreed to blindly obey their superiors and who are ordered to fight in unjust wars are released from their duty to deliberate about the merits of the acts that they are ordered to perform. This is because their agreements result in the combatants’ permissible lack of a necessary capacity for moral responsibility. Thus, the combatants are not morally responsible for their wrongful acts—their moral responsibility is “transferred” to their superiors. We argue, first, (...) that Benbaji’s own reasoning suggests that the agreements entered into between the combatants and their superiors are not binding and, second, that even if such agreements are binding, those combatants who obey their orders to fight are nevertheless morally responsible for their wrongful acts. Thus, Benbaji has failed to show that the combatants are permitted to act as ordered. By critically examining Benbaji’s view, then, we defend the revisionist position that just and unjust combatants are morally unequal. (shrink)

A survey of just war theory literature reveals the existence of quite different lists of principles. This apparent arbitrariness raises a number of questions: What is the relation between ad bellum and in bello principles? Why are there so many of the former and so few of the latter? What order is there among the various principles? To answer these questions, I first draw on some recent work by Jeff McMahan to show that ad bellum and in bello principles are (...) not, as often portrayed, independent—the justice of conduct in war largely presupposes the justice of the recourse to war. Undermining this independence claim is one important step toward revealing the unified logical structure of just war theory. I then argue that we can see the dependence of the jus in bello upon the jus ad bellum , not just in the content of certain principles, but also in the structure of the two sets of principles: I construct a one-to-one mapping between ad bellum and in bello principles. In doing so, I argue also that the shared structure successfully finds place for the questions central to the evaluation of the morality of war: what is a sufficient provocation to use force, what objectives may be sought by force, why or for what ends, who has authority to decide to use force, and when or in what circumstances? Despite variations in expression, the theory allows for a coherent and comprehensive evaluation of morality in warfare. (shrink)

A variety of ethical objections have been raised against the military employment of uninhabited aerial vehicles (UAVs, drones). Some of these objections are technological concerns over UAVs abilities’ to function on par with their inhabited counterparts. This paper sets such concerns aside and instead focuses on supposed objections to the use of UAVs in principle. I examine several such objections currently on offer and show them all to be wanting. Indeed, I argue that we have a duty to protect an (...) agent engaged in a justified act from harm to the greatest extent possible, so long as that protection does not interfere with the agent's ability to act justly. UAVs afford precisely such protection. Therefore, we are obligated to employ UAV weapon systems if it can be shown that their use does not significantly reduce a warfighter's operational capability. Of course, if a given military action is unjustified to begin with, then carrying out that act via UAVs is wrong, just as it would be with any weapon. But the point of this paper is to show that there is nothing wrong in principle with using a UAV and that, other things being equal, using such technology is, in fact, obligatory. (shrink)

According to the dominant position in the just war tradition from Augustine to Anscombe and beyond, there is no "moral equality of combatants." That is, on the traditional view the combatants participating in a justified war may kill their enemy combatants participating in an unjustified war - but not vice versa (barring certain qualifications). I shall argue here, however, that in the large number of wars (and in practically all modern wars) where the combatants on the justified side violate the (...) rights of innocent people ("collateral damage"), these combatants are in fact liable to attack by the combatants on the unjustified side. I will support this view with a rights-based account of liability to attack and then defend it against a number of objections raised in particular by Jeff McMahan. The result is that the thesis of the moral equality of combatants holds good for a large range of armed conflicts while the opposing thesis is of very limited practical relevance. (shrink)

According to a widespread view, the same constraints that limit the use of otherwise immoral measures in individual self-defense apply to collective self-defense too. I try to show that this view has radical implications at the level of jus in bello, implications which have not been fully appreciated. In particular, if the necessity condition must be satisfied in all cases of killing in war, then most fighting would turn out to be unjust. One way to avoid this result is to (...) adopt a contractualist view of killing in war, a view which interprets the necessity condition in a way that is more permissive with regard to killing combatants in war. At least in this respect, a contractualist view of killing in war has an advantage over other candidates in explaining how wars might be fought justly. (shrink)

In this paper the author aims to explain the consequences of the implicit application of the zero-sum game model of distribution of moral responsibility for war, i.e., for causing war, within the context of the dominant perspective of modern-day ethics of war – Just War Theory. The main criterion of the jus ad bellum concept of Just War Theory, “just cause,” recognizes the possibility of only one “cause” of war, and every attempt to further analyze and investigate deeper causes of (...) war is automatically perceived through the zero-sum lens, as an attempt to justify or excuse the unjust side in war. No such thing happens when analyzing other, extremely morally troubling and disturbing phenomena as we invest significant effort into attempting to explain evil without this effort ever being understood as a justification attempt. The author demonstrates how the described approach in Just War Theory prevents us from fully understanding war, and thus implicitly from how to normatively prescribe human actions in and regarding war. The author also asserts that this perspective actually represents a presupposition concerning the possibility of justness of war. The author concludes that, in order to fully understand war and properly morally evaluate it, ethics of war must adopt a non-zero-sum model of distribution of moral responsibility and acknowledge the existence of a wide variety of causes of war.

This paper uses a novel account of non-ideal political action that can justify radical responses to severe climate injustice, including and especially deliberate attempts to engineer the climate system in order reflect sunlight into space and cooling the planet. In particular, it discusses the question of what those suffering from climate injustice may do in order to secure their fundamental rights and interests in the face of severe climate change impacts. Using the example of risky geoengineering strategies such as sulfate (...) aerosol injections, I argue that peoples that are innocently subject to severely negative climate change impacts may have a special permission to engage in large-scale yet risky climate interventions to prevent them. Furthermore, this can be true even if those interventions wrongly harm innocent people. (shrink)

Does a person's liability to attack during a war depend on the nature of their individual causal contribution to the (unjust) threat posed? If so, how? The recent literature on the ethics of war has become increasingly focused on questions of this kind. According to some views on these matters, your liability hinges on the extent of your causal contribution: the larger your contribution to an unjust threat, the larger the amount of harm that we can impose on you in (...) order to avert the threat. Some philosophers have suggested that we can ground a quite general principle of civilian immunity on this basis. But, do causal contributions really come in degrees? Can we make sense of a graded notion of causal contribution that can be relevant to debates about liability in war? I argue there is good reason to be sceptical.

Traditional just war doctrine holds that political leaders are morally responsible for the decision to initiate war, while individual soldiers should be judged solely by their conduct in war. According to this view, soldiers fighting in an unjust war of aggression and soldiers on the opposing side seeking to defend their country are morally equal as long as each obeys the rules of combat. Revisionist scholars, however, maintain that soldiers who fight for an unjust cause bear at least some responsibility (...) for advancing an immoral end, even if they otherwise fight ethically. This article examines the attitudes of the American public regarding the moral equality of combatants. Utilizing an original survey experiment, we find that the public's moral reasoning is generally more consistent with that of the revisionists than with traditional just war theory. Americans in our study judged soldiers who participate in unjust wars as less ethical than soldiers in just wars, even when their battlefield conduct is identical, and a large proportion supported harsh punishments for soldiers simply for participating in unjust wars. We also find, however, that much of the American public is willing to extend the moral license of just cause significantly further than revisionist scholars advocate: half of the Americans in our survey were willing to allow an unambiguous war crime—a massacre of innocent women and children—to go unpunished when the act was committed by soldiers fighting for a just cause. Our findings suggest that incorporation of revisionist principles into the laws of war would reinforce dangerous moral intuitions encouraging the killing of civilians. (shrink)
