Helen Frowe has recently offered what she calls a “practical” account of self-defense. Her account is supposed to be practical by being subjectivist about permissibility and objectivist about liability. I shall argue here that Frowe first makes up a problem that does not exist and then fails to solve it. To wit, her claim that objectivist accounts of permissibility cannot be action-guiding is wrong; and her own account of permissibility actually retains an objectivist (in the relevant sense) element. In addition, her attempt to restrict subjectivism primarily to “urgent” situations like self-defense contradicts her own point of departure and is either incoherent or futile. Finally, the only actual whole-heartedly objectivist account she criticizes is an easy target; while those objectivist accounts one finds in certain Western European jurisdictions are immune to her criticisms. Those accounts are also clearly superior to hers in terms of action-guidingness.

Yitzhak Benbaji defends the view that soldiers on both the ‘just’ and the ‘unjust’ side in a war have the same liberty right to kill one another, because soldiers have ‘tacitly accepted’ the egalitarian laws of war and thereby waived their moral rights not to be attacked. I argue that soldiers on the ‘just’ side have not accepted the egalitarian laws of war; even if they had, they would not thereby have waived their moral rights not to be attacked. Moreover, the egalitarian laws of war and ‘the war convention’ are not fair and mutually beneficial, and so would not be accepted. Benbaji does not come to grips with the problem of the killing of civilians in war: his idea that states could waive the moral rights of their citizens is untenable

Victor Tadros thinks the idea that in a conflict both sides may permissibly use force should (typically) be rejected. Thus, he thinks that two shipwrecked persons should not fight for the only available flotsam (which can only carry one person) but instead toss a coin, and that a bomber justifiably attacking an ammunitions factory must not be counterattacked by the innocent bystanders he endangers. I shall argue that Tadros’s claim rests on unwarranted assumptions and is also mistaken in the light of the moral reasoning that he himself offers in support of his ‘means principle’

In a recent article Yvonne Chiu argues that nonuniformed combat is impermissible. However, her argument that by fighting without uniforms nonuniformed guerillas coerce civilians into participating in the armed conflict and thus into surrendering their immunity (their right not to be attacked) fails: there is no coercion, no participation, and no surrendering of immunity. Yet even if this argument of hers were correct, it would still not show that such “coercion” would amount to a rights infringement. Moreover, even if it did, there are examples that show that such an infringement would sometimes be perfectly justified. Finally, if she were right that forcing civilians into a moral position that they have not accepted or chosen is absolutely wrong, then this would affect the moral status of uniformed combatants no less than it would affect the moral status of nonuniformed ones.

I argue that rights-forfeiture by itself is no path to permissibility at all (even barring special circumstances), neither in the case of self-defense nor in the case of punishment. The limiting conditions of self-defense, for instance – necessity, proportionality (or no gross disproportionality), and the subjective element – are different in the context of forfeiture than in the context of justification (and might even be absent in the former context). In particular, I argue that a culpable aggressor, unlike an innocent aggressor, forfeits rights against proportionate defense, including unnecessary defense (as well as rights against the infliction of proportionate non-defensive harm). Yet, I demonstrate that this stance need not lead to the abandonment of the necessity condition of justified self-defense in the case of a culpable aggressor. Since justification and liability are not the same, there is no reason to assume that the necessity condition of justified self-defense must be explained under an appeal to the aggressor’s rights. Parallel arguments apply to the other limiting conditions of permissible self-defense as well as to the limiting conditions of permissible punishment. Accordingly, I also sketch alternative explanations of the proportionality requirement and the subjective element. All these alternative explanations appeal to a principle of precaution: instead of explaining the unjustifiability of unnecessarily harming a culpable attacker or wrongdoer by an appeal to the rights of the attacker or wrongdoer himself, one can also, and better, explain it by a requirement to take reasonable precautions against violating the rights of innocent people.

McMahan’s own example of a symmetrical defense case, namely his tactical bomber example, opens the door wide open for soldiers to defend their fellow-citizens (on grounds of their special obligations towards them) even if as part of this defense they target non-liable soldiers. So the soldiers on both sides would be permitted to kill each other and, given how McMahan defines “justification,” they would also be justified in doing so and hence not be liable. Thus, we arrive, against McMahan’s intentions, at a moral equality of combatants. In addition, his own account of liability cannot deal adequately with symmetrical defense cases in the first place. This undermines his presupposition that justification defeats liability, which is central to his defense of the moral inequality of combatants. I shall argue that McMahan’s attempts to counter these objections fail and that therefore his general claim of the moral inequality of combatants remains unpersuasive.

Thomas Pogge labels the idea that each person owes each other person equal respect and concern ‘ethical cosmopolitanism’ and correctly states that it is a ‘non-starter’. He offers as an allegedly more convincing cosmopolitan alternative his ‘social justice cosmopolitanism’. I shall argue that this alternative fails for pretty much the same reasons that ‘ethical cosmopolitanism’ fails. In addition, I will show that Pogge's definition of cosmopolitanism is misleading, since it actually applies to ethical cosmopolitanism and not to social justice cosmopolitanism. This means that cosmopolitanism as defined by Pogge is wrong in the light of his own arguments and that Pogge is not even a cosmopolitan in the sense of his own definition. I will further show that he is also not a cosmopolitan if cosmopolitanism is defined as a philosophical position involving the claim that state borders have no fundamental moral significance.

Many philosophers have criticized John Rawls’s Law of Peoples. However, often these criticisms take it for granted that the moral conclusions drawn in A Theory of Justice are superior to those in the former book. In my view, however, Rawls comes to many of his 'conclusions' without too many actual inferences. More precisely, my argument here is that if one takes Rawls’s premises and the assumptions made about the original position(s) seriously and does in fact think them through to their logical conclusions, both 'A Theory of Justice' and 'The Law of Peoples' have abysmally counterintuitive and immoral implications. To wit, if the members in the original position think, as Rawls suggests,that their society is closed and they will have no interaction with outsiders, and if, furthermore, they are self-interested and concerned with the basic structure of their own society, than there is absolutely no reason for them to use the terms “persons” or “least advantaged” in the formulation of the two principles. Rather, they will use the terms “citizens of our society” and “least advantaged of our society” instead. But thus revised, the principles of justice imply that the genocide or the enslavement of outsiders is unobjectionable. I will consider attempts to block this conclusion and demonstrate that they all fail. The Law of Peoples, moreover, faces similar problems.

Over the years a few authors have argued that Rawls’s ideal theory of justice is useless for the real world. This criticism has been largely ignored by Rawlsians, but in the light of a recent accumulation of such criticisms, some authors (in particular Holly Lawford-Smith, A. John Simmons, Zofia Stemplowska and Laura Valentini) have tried to defend ideal theory. In this article I will recapitulate the precise problem with Rawls’s ideal theory, argue that some of Rawls’s defenders misconceive it, and show that recent attempts to rescue Rawls’s ideal theory from the charge of being useless fail. While there are useful kinds of ideal theory, Rawls’s is not one of them. In addition, Rawls’s very tentative suggestions for some kind of bridge between ideal and non-ideal theory are contradictory insofar as they implicitly presuppose the non-existence of the problem they are meant to solve. Thus, Rawls’s “non-ideal theory” too, is useless, and not so much a theory at all but a set of ad hoc stipulations. Finally, I will show that certain attempts within the global justice debate to use some variation of the original position to directly derive guidelines for the real world are misguided and yield no useful results.

A standard example of a justified aggressor is the tactical bomber who is about to destroy an ammunitions factory in a proportionate, justified military attack, full well knowing that an innocent civilian bystander will also be killed by his attack (“collateral damage”). Intuitively it seems hard to believe that the innocent bystander threatened by the tactical bomber is morally prohibited from killing him in self-defense. Yet, Stephen R. Shalom indeed endorses such a prohibition. I shall argue that all the examples Shalom offers in support of his view are disanalogous to the case in question, and provide examples that are analogous and strongly suggest that Shalom’s claim leads to counter-intuitive implications. Moreover, I will provide a clear-cut case that demonstrates that Shalom cannot rely on a general principle prohibiting lethal violence against permissible violence. Thus, I conclude that Shalom has failed to provide a convincing argument in support of his case.

David Rodin denies that defensive wars against unjust aggression can be justified if the unjust aggression limits itself, for example, to the annexation of territory, the robbery of resources or the restriction of political freedom, but would endanger the lives, bodily integrity or freedom from slavery of the citizens only if the unjustly attacked state actually resisted the aggression. I will argue that Rodin's position is not correct. First, Rodin's comments on the necessity condition and its relation to an alleged "duty to retreat" misinterpret the law, and a correct interpretation of the law is not only compatible with, but implies a permission to resist the "bloodless invader," and this is also the correct view from the perspective of morality. Second, Rodin's remarks on the proportionality of self-defense against conditional threats focus on physical or material harm but implausibly ignore the severity of the violations of autonomy and of the socio-legal or moral order that such conditional threats involve. Third, I will address Rodin's claim that defensive wars against "political aggression" are disproportionate because they risk the lives of those defended in an attempt to secure lesser interests. I will argue that this take on proportionality misses the point in an important respect, namely by confusing wide and narrow proportionality, and makes unwarranted assumptions about the alleged irrationality or impermissibility of incurring or imposing lethal risks to safeguard less vital interests. Next, I will also show that while Rodin talks of a "myth of national self-defense" and of the necessity of moving beyond traditional just war theory and international law, it is actually his interpretation of just war theory and international law that weaves myths. Finally, I will argue that Rodin's views on national self-defense on the one hand, and "war as law enforcement" on the other, are incoherent.

Is there is a moral obligation to militarily intervene in another state to stop a genocide from happening (if this can be done with proportionate force)? My answer is that under exceptional circumstances a state or even a non-state actor might have a duty to stop a genocide (for example if these actors have promised to do so), but under most circumstances there is no such obligation. To wit, “humanity,” states, collectives, and individuals do not have an obligation to make such promises in the first place or to create institutions that would impose a legal obligation of intervention upon them. Nor do states or persons or humanity “collectively” have – originally, without specifically creating such duties by contracts or promises – any pro tanto or special duties to save strangers at considerable cost to themselves or their own citizens (including their soldiers). That is, these costs do not merely override a duty to intervene, but rather there is no such duty to begin with – as shown by the fact that in such cases of non-intervention agents would not owe those they let die any compensation: if I do not save someone’s life because saving him would have cost me my arm or would have come with a high risk of losing my own life or would have forced me to kill innocent bystanders, I do not owe this person compensation. Thus the point of this chapter is that there is no “natural” or “general” or “original” duty to militarily intervene (or to create a legal obligation) to stop a genocide. I will consider and refute a number of arguments to the contrary, for example by Lango, Tan, and Pattison.

David K. Chan wants to save the DDE from the considerable criticism levelled against it, by making the moral distinction it refers to rest on a difference in desire instead of in intention. I argue that the revised version, too, is counter-intuitive and confuses the blameworthiness of an actor with the wrongness of the act. It also invites abuse instead of preventing it. Besides, Chan's DDE omits three of the four criteria of the traditional DDE, and it is couched in terms of lesser objectionability, while the traditional DDE is couched in terms of permission. Therefore, Chan's DDE has so little in common with the traditional DDE that it should not even count as a revised version of it.

Jonathan Quong proposes the following “Stringency Principle” for proportionality in self-defense: “If a wrongful attacker threatens to violate a right with stringency level X, then the level of defensive force it is proportionate to impose on the attacker is equivalent to X.” I adduce a counter-example that shows that this principle is wrong. Furthermore, Quong assumes that what determines the stringency of a person’s right is exclusively the amount of force that one would have to avert from someone else in order to have a necessity justification for one’s transgressing the right in order to avert said force. Yet, Quong provides no argument as to why, first, the stringency of a right should be measured exclusively with reference to permissible rights-infringement; and second, he provides no explanation as to why the permissibility of the rights-infringement should be established with reference to “someone else,” namely with reference to an “innocent person,” instead of with reference to the person against whom the right in question is actually being held: the aggressor. I argue that the latter option is certainly the more plausible one, but so amended the stringency principle will be unable to adjudicate any substantive questions about proportionality in self-defense. In particular, Quong’s account cannot “explain” – contrary to what Quong claims – the allegedly intuitive judgment that one must not kill in defense of property or in order to avoid minor injuries.

McMahan argues that justification defeats liability to defensive attack (which would undermine the thesis of the "moral equality of combatants"). In response, I argue, first, that McMahan’s attempt to burden the contrary claim with counter-intuitive implications fails; second, that McMahan’s own position implies that the innocent civilians do not have a right of self-defense against justified attackers, which neither coheres with his description of the case (the justified bombers infringe the rights of the civilians) nor with his views about rights forfeiture, is unsupported by independent argument, and, in any case, extremely implausible and counter-intuitive; and third, that his interpretation of the insulin case confuses the normative relations between an agent’s justification and non-liability on the one hand and permissible or impermissible interference with the agent’s act on the other. Similar confusions, fourth, affect his discussion of liability to compensation.

In a recent paper, McMahan argues that his ‘Responsibility Account’, according to which ‘the criterion of liability to attack in war is moral responsibility for an objectively unjustified threat of harm’, can meet the challenge of explaining why most combatants on the unjustified side of a war are liable to attack while most civilians (even on the unjustified side) are not. It should be added, however, that in the light of his rejection of the ‘moral equality of combatants’, McMahan would also have to explain why combatants on the justified side of a war are not liable to attack. I will argue here that McMahan does not succeed in meeting these challenges.

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.

Saba Bazargan proposes a novel “hybrid” justification for the killing of minimally responsible threats (MRTs). His account allegedly combines two elements, namely “the complex account of liability” and “the lesser-evil discounting view.” I argue that Bazargan’s conclusion that minimally responsible threats can sometimes be killed as well as certain other conclusions that Bazargan regards as a particular advantage of his hybrid account are single-handedly generated by one element of the “hybrid account,” namely by the lesser-evil discounting view. The lesser-evil discounting view therefore does not need to be combined with “the complex account of liability,” nor, indeed, with any account of liability. Thus, Bazargan’s hybrid view is redundant. Moreover, I will argue that both the hybrid view and the lesser evil discounting view of killing MRTs have strongly counter-intuitive implications and should therefore be rejected.

In this paper, I will provide a conceptual analysis of the term self-defense and argue that in contrast to the widespread “instrumentalist” account of self-defense, self-defense need not be aimed at averting or mitigating an attack, let alone the harm threatened by it. Instead, on the definition offered here, an act token is self-defense if and only if a) it is directed against an ongoing or imminent attack, and b) the actor correctly believes that the act token is an effective form of resistance or the act token belongs to an act type that usually functions as a means to resist an attack. While resistance is effective in making the attack more difficult, it can often be overcome and therefore does not necessarily stop or mitigate the attack. This concept of self-defense, I shall argue, not only matches ordinary language use and plausible accounts of self-defense in the legal literature but also has important practical implications in helping to avoid confusions about necessity and proportionality. In particular, it avoids the notorious problem of the “knowingly helpless rape victim” whose futile struggle against the rapist (futile in terms of averting or mitigating harm) counter-intuitively could not count as justified self-defense on an instrumentalist account.

I shall argue that in some wars both sides are (as a collective) justified, that is, they can both satisfy valid jus ad bellum requirements. Moreover, in some wars – but not in all – the individual soldiers on the unjustified side (that is, on the side without jus ad bellum) may nevertheless kill soldiers (and also civilians as a side-effect) on the justified side, even if the enemy soldiers always abide by jus in bello constraints. Traditional just war theory and self-proclaimed “revisionist” just war theory think otherwise since the former focuses on the law enforcement or public authority justification for inflicting harm and the latter on the self-defense justification. These are both intrinsically asymmetrical justifications: there is no justified self-defense (properly understood) against justified self-defense, nor is there justified law-enforcement against justified law-enforcement. However, there can, as I will show, be justified self-defense against force that is justified by a necessity justification, and there can be force justified by a necessity justification being used against force that is also justified by a necessity justification. The necessity justification is not intrinsically asymmetrical, and it is an indispensable justification in the context of war. Moreover, with regard to some forms of inflicting harm on others one may give special weight to one’s own interests and the interests of those to whom one has special responsibilities when assessing the proportionality of those acts. That is, the proportionality calculation may be agent-relative. This is in particular so in the case of foreseeably preventing innocent and non-threatening people from being saved (for instance, by shooting down a tactical bomber who would have saved them by destroying an ammunitions factory) but less so in the case of the intentional or foreseeable direct harming of innocent and non-threatening people (dropping bombs on people standing near an ammunitions factory). In the light of these considerations, I will then answer the question as to when soldiers may justifiably participate in war (and when not).
