The current armed conflict in Afghanistan (briefly, the Afghan conflict) is viewed through the lens of a just war theory. In particular, the question stated by the title is explored by means of a generalized just cause principle. For brevity, empirical, practical, and legal issues about the Afghan conflict are mostly set aside. Hence a definite answer to the question is not proposed. Instead, the main aim is to clarify the question. Specifically, the question is amplified, by distinguishing putative just causes of countering terrorism, countering an insurgency, and countering extreme violations of basic human rights. Apparently, however, U.S. government officials (e.g., President Barack Obama) and U.S. military commanders (e.g., General Stanley McChrystal) have mixed goals or motives concerning current U.S.military operations in Afghanistan. Nonetheless, from the standpoint of a just war theory, it is instructive to analytically distinguish these putative just causes, and to consider them separately. Additionally, it is instructive to consider how they might be combined. Consequently, a fourth putative just cause is considered: countering violent spoilers of peacebuilding.

The just war tradition is an evolving body of tenets for determining when resorting to war is just and how war may be justly executed. Rethinking the Just War Tradition provides a timely exploration in light of new security threats that have emerged since the end of the Cold War, including ongoing conflicts in the Middle East, threats of terror attacks, and genocidal conflicts within states. The contributors are philosophers, political scientists, a U.S. Army officer, and a senior analyst at the Center for Defense Information. They scrutinize some familiar themes in just war theory from fresh and original angles, and also explore altogether new territory. The diverse topics considered include war and the environment, justice in the ending of war, U.S. military hegemony, a general theory of just armed-conflict principles, supreme emergencies, the distinction between combatants and noncombatants, child soldiers, the moral equality of all soldiers, targeted assassination, preventive war, right authority, and armed humanitarian intervention. Clearly written and free of jargon, this book illustrates how the just war tradition can be rethought and applied today. Contributors include Mark Woods, Eric Patterson, Harry van der Linden, John Lango, Frederik Kaufman, Pauline Kaurin, Reuben Brigety II, Rachel Stohl, Michael Brough, Whitley Kaufman, Jordy Rocheleau, Hartley Spatt, and Robert Hoag.

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

Traditionally, the just war principle of last resort requires that, before resorting to war, every reasonable alternative measure must be attempted. My view is that traditional just war principles should be generalized, so as to be applicable to military actions of all sorts—for example, armed humanitarian interventions and counterinsurgency operations. In this paper, such a generalized just war theory is presupposed. In particular, I shall presuppose a generalized last resort principle that requires that, before using military force, every reasonable alternative measure must be attempted. My thesis is that among these alternative measures is nonviolent action. For concreteness, the new U.S. counterinsurgency field manual is examined. The generalized last resort principle morally obligates a U.S. counterinsurgency operation to use the means of nonviolent action, whenever it is reasonable to do so. Pacifism and just war theory are often portrayed as rivals, but this paper explores one way in which just war theory could benefit from the tradition of nonviolence
