Minimal responsibility threateners are epistemically justified but mistaken in thinking that imposing a nonnegligible risk on others is permissible. On standard accounts, an MRT forfeits her right not to be defensively killed. I propose an alternative account: an MRT is liable only to the degree of harm equivalent to what she risks causing multiplied by her degree of responsibility. Harm imposed on the MRT above that amount is justified as a lesser evil, relative to allowing the MRT to kill her (...) victim. This hybrid account, which generalizes to those are who are more than minimally responsible, has considerable advantages. (shrink)

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

The practices of using hostages to obtain concessions and using human shields to deter aggression share an important characteristic which warrants a univocal reference to both sorts of conduct: they both involve manipulating our commitment to morality, as a means to achieving wrongful ends. I call this type of conduct “moral coercion”. In this paper I (a) present an account of moral coercion by linking it to coercion more generally, (b) determine whether and to what degree the coerced agent is (...) liable for the harms resulting from acceding to moral coercion, and (c) investigate factors relevant to determining whether we ought to accede to moral coercion. In so doing, I provide grounds for the intuition that we “allow evil to succeed” when we accede to moral coercion. (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)

Some collateral harms affecting enemy civilians during a war are agentially mediated – for example, the US-led invasion of Iraq in 2003 sparked an insurgency which killed thousands of Iraqi civilians. I call these ‘collaterally enabled harms.’ Intuitively, we ought to discount the weight that these harms receive in the ‘costs’ column of our ad bellum proportionality calculation. But I argue that an occupying military force with de facto political authority has a special obligation to provide minimal protection to the (...) civilian population. As a result, when an occupying military force collaterally enables a harm affecting the civilian population, the weight that the harm ought to receive in the ad bellum proportionality calculation is unaffected by the fact that the harm is agentially mediated – it ought to be weighed at least as heavily as those harms that the occupying force collaterally commits directly. As a result, satisfying the ad bellum proportionality constraint in wars of territorial occupation is more difficult than it has been thought. (shrink)

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)

The principle of noncombatant immunity prohibits warring parties from intentionally targeting noncombatants. I explicate the moral version of this view and its criticisms by reductive individualists; they argue that certain civilians on the unjust side are morally liable to be lethally targeted to forestall substantial contributions to that war. I then argue that reductivists are mistaken in thinking that causally contributing to an unjust war is a necessary condition for moral liability. Certain noncontributing civilians—notably, war-profiteers—can be morally liable to be (...) lethally targeted. Thus, the principle of noncombatant immunity is mistaken as a moral (though not necessarily as a legal) doctrine, not just because some civilians contribute substantially, but because some unjustly enriched civilians culpably fail to discharge their restitutionary duties to those whose victimization made the unjust enrichment possible. Consequently, the moral criterion for lethal liability in war is even broader than reductive individualists have argued. (shrink)

According to “epistemic-based contingent pacifism” a) there are virtually no wars which we know to be just, and b) it is morally impermissible to wage a war unless we know that the war is just. Thus it follows that there is no war which we are morally permitted to wage. The first claim (a) seems to follow from widespread disagreement among just war theorists over which wars, historically, have been just. I will argue, however, that a source of our inability (...) to confidently distinguish just from unjust wars lies in how we evaluate “morally heterogeneous” wars—i.e., wars with just and unjust aims. Specifically, the practice of reaching a univocal evaluation of a morally heterogeneous war as a whole by aggregating the evaluations of that war’s just and unjust aims is wrongheaded, because it undermines the action-guiding character of jus ad bellum. We ought instead to adopt what I call the “disaggregate approach” to jus ad bellum, according to which we evaluate the various aims of a war individually, without aggregating them into an evaluation of the war as a whole. Adopting this approach will eliminate a source of our disagreement over which wars have been just, and will ipso fact eliminate a basis for epistemic-based contingent pacifism. (shrink)
