War, reciprocity and the moral equality of combatants

In this article I address differences between myself and Uwe Steinhoff in relation to the moral principle of reciprocity and its implications for the doctrine of the moral equality of combatants. Whereas I agree with Steinhoff that there is a principle of reciprocity in play in war, contra Steinhoff, I suggest that this principle and, indeed, moral principles of reciprocity more generally, are particularist principles, although if conventionalised or given legal status they can assume a generalised form. Moreover, I also hold that there is a moral difference between those fighting a just war and those fighting an unjust war and this difference, taken in conjunction with the moral equality of combatants doctrine, generates a degree of moral complexity that seems to have gone unrecognised by Steinhoff (and, for that matter, by the two dominant schools of thought in this area, revisionists and Walzerians).
