This essay argues that the best starting point for discussions of the Principle of Discrimination (PD) is its most basic formulation: In wartime, certain enemy subjects should receive better treatment than others. Other formulations of the PD ? in particular, those centered on the concept of noncombatant immunity ? have sought to identify a single criterion that can be used as the basis for sorting enemy subjects into two (and only two) classes. However, a historical and legal analysis of the (...) principle indicates that three distinct criteria ? the conduct of individuals, their status, and their guilt or innocence ? have all been seen as relevant for determining the appropriate treatment of the enemy. In this essay, I formulate an expanded version of the PD, which calls for the proportionate treatment of enemy subjects based on evaluations of all three of these criteria. (shrink)

Frequently, the just war principle of noncombatant immunity is interpreted as morally prohibiting the intentional targeting of noncombatants. Apparently, many just war theorists assume that to target means to (intend to) kill. Now that effective nonlethal weapons have been envisaged, it should be evident that there is no conceptual connection between intentionally targeting and intentionally killing. For, using nonlethal weapons, there could be intentional targeting without intentional killing. This paper explores the question of whether the noncombatant immunity principle should be (...) revised, so as to allow uses of nonlethal weapons. Preliminary to answering this question, some other questions are explored, among which are the following. Why should a noncombatant immunity principle be accepted? Why is it morally permissible to intentionally target enemy combatants? Are noncombatants grievously harmed when they are incapacitated by nonlethal weapons? Is it morally permissible to intentionally incapacitate enemy combatants with nonlethal weapons, while knowingly but not intentionally incapacitating noncombatants? In order to focus on moral questions involving nonlethal weapons, questions about their effectiveness or legality are set aside. Instead of the idea of noncombatant immunity as expressed above, a delimited principle of noncombatant immunity is proposed—namely, that, in the conduct of war, the intentional grave injuring or killing of noncombatants is morally prohibited. Also proposed is a principle of noncombatant targeting, which would allow some uses of nonlethal weapons to intentionally incapacitate noncombatants. (shrink)
