Killing in War presents the Moral Equality of Combatants with serious, and in my view insurmountable problems. Absent some novel defense, this thesis is now very difficult to sustain. But this success is counterbalanced by the strikingly revisionist implications of McMahan’s account of the underlying morality of killing in war, which forces us into one of two unattractive positions, contingent pacifism, or near-total war. In this article, I have argued that his efforts to mitigate these controversial implications fail. The reader (...) is left stranded: to reach plausible conclusions, Walzer deployed an implausible conception of our rights to life; McMahan’s more rigorous account of those rights generates untenable conclusions. Absent new developments, it seems that the prospects for grounding the ethics of war in individual rights are poor: any theory of our rights to life that is sufficiently indiscriminate to work in the chaos of war is not discriminating enough to be a plausible theory of our rights to life. Perhaps by rejecting the ideal of the rights-respecting war altogether we might develop an alternative theory of justified warfare, which marries theoretical soundness with conclusions that we can more confidently support.

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. The appearance that causal contributions come in degrees is just an illusion that can be explained away. (shrink)
