In "The Ethics of America’s Afghan War," Richard W. Miller argues that reflecting on whether and how to end the war in Afghanistan exposes serious deficiencies in just war theory. I agree, though for different reasons than those canvassed by Professor Miller. Miller argues that by focusing on the traditional categories of just cause, proportionality, and necessity (or last resort), just war theory obscures the importance of broader geostrategic considerations that he believes are the most plausible—though ultimately for Miller insufficient—rationale for continuing with the strategy of large-scale counterinsurgency in Afghanistan. I doubt that geostrategic considerations can play the role in moral assessment that Miller believes they do. But the phenomena he is pointing to do illuminate important defects in traditional just war theory.
