A friend links us to this article by David Aikman who writes that the moral criteria Just War thinking are teetering on the brink of obsolescence in an age in which one side regards such criteria with disdain. He argues that we must not discard the principles of Just War but that we need to rethink what "Just War" means in an age of jihad:
Just war principles work successfully only among nations that acknowledge the same moral laws at work, as in Europe, for example, in general before World War I. Now, however, we are all in a wider and starker conflict, in which ruthless Islamic ideologists are prepared to immolate their own children for the sake of ultimate victory. We should not be pressured by the enormity of the challenge they pose to civilized life to abandon our own rules of "just war." But we need to think through-and make public-how to cope with guerrilla adversaries who operate according to barbaric and totalitarian rules. Civilization is at stake-not only ours, but the world's. Do we have the moral imagination to oppose such adversaries without compromising the very integrity we fight to protect?
For my part I'm not sure exactly which Just War criteria are threatened by the Islamist assault upon the West (See here for a helpful discussion of Just War theory). I do agree, however, that we need to rethink some aspects of Just War theory. For instance, we need to clarify the concept of proportionate response, the question of who is a non-combatant, and what constitutes torture, but I agree with Aikman that the tradition of Just War and the principles which comprise it should not be abandoned.
