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

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

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
