In recent decades, revisionist philosophers have radically challenged the orthodox just war theory championed by Michael Walzer in the 1970s. This review considers two new contributions to the debate, Benbaji and Statman’s War by Agreement and Ripstein’s Kant and the Law of War, which aim to defend the traditional war convention against the revisionist attack. The review investigates the two books’ respective contractarian and Kantian foundations for the war convention, their contrast with the revisionist challenge, and their points of disagreement. (...) Building on the responses to Ripstein in the edited collection, The Public Uses of Coercion and Force, and providing an overview of the broader debate, the review offers an analysis of the two books’ positions on the relationship between the morality and laws of war, on just cause and the crime of aggression, and on the equality between just and unjust combatants.

Many believe that in?supreme emergencies? collectives are granted what I elsewhere call?special permissions?, permissions to carry out self-defensive acts which would otherwise be morally forbidden. However, there appears to be a continuum between non-emergency, emergency and supreme-emergency situations, which gives rise to the following problem: If special permissions are granted in supreme emergencies, they should apply, mutatis mutandis, to less extreme cases too. If, to save itself from wholesale massacre, a collective is allowed to kill thousands of noncombatants on the (...) side of the aggressor, then to save itself from a less murderous campaign, a collective should be allowed to kill several hundreds of noncombatants, and so on. But this conclusion seems to undermine the most fundamental ideas of just war theory. The purpose of the paper is to discuss possible solutions to this problem. I contend that a contractarian view of the war convention offers the most attractive solution, though, at the end of the day, I am not sure that it will work. (shrink)
