Modern warfare cannot be conducted without civilians being killed. In order to reconcile this fact with the principle of discrimination in just war theory, the principle is applied through the doctrine of double effect. But this doctrine is morally inadequate because it is too permissive regarding the risk to civilians. For this reason, Michael Walzer has suggested that the doctrine be supplemented with what he calls the idea of double intention: combatants are not only to refrain from intending to harm (...) civilians; they are also to take precautions to reduce risk to civilians, even at the expense of increasing risk to themselves. The article develops the idea of double intention by addressing two questions: What does it mean to intend to reduce civilian risk, and how much should civilian risk be reduced? The results of this discussion are then used to consider a moral issue that arises in technologically asymmetric warfare, namely, the extent to which the use of precision-guided munitions, which allow more accurate targeting, can by itself bear the moral burden imposed by the principle of discrimination.

We are grateful to Professors Nick Fotion, Bashshar Haydar and David L. Perry for their illuminating discussions of our paper, ?Military ethics of fighting terror: An Israeli perspective?, published in the present issue of the Journal of Military Ethics. We also thank the editors of the Journal for allowing us to add the present response. Professors Fotion, Haydar and Perry raise many significant issues. We will, however, presently address just a few of them, leaving the discussion of the other interesting (...) points to other occasions. (shrink)
