War for the Wrong Reasons: Lessons from Law

Abstract

In Ethics for Enemies, Frances Kamm argues that, under certain conditions, it is morally permissible for a state to launch a war for opportunistic reasons. We consider how law might shed light on Kamm’s argument. Part I addresses the application of criminal and tort law to individual acts of violence analogous to the acts of war analyzed by Kamm. It primarily argues that these bodies of law rely on a framework for determining legal permissibility that runs counter to, and perhaps demonstrates weaknesses in, Kamm’s framework for assessing moral permissibility. Part II considers the law of war. It maintains that, although modern law permits certain opportunistic acts of war, the law does so on terms that cut against Kamm’s claim as to their moral permissibility.
