War overreaches routinely. Overkill is one of the self-revealing--if thinly veiled and desperately denied--principles of war. The loss and cost for "regime change" in Iraq is inestimable in every dimension. But sometimes war's routine overreaches in the name of "good" are manifest in strikingly soul-piercing atrocities. Vietnam gave us My Lai. Iraq has already given us Abu Ghraib. Iraq now gives us a second atrocity--Haditha. The civilian massacre by American Marines in this Iraqi village may eclipse Abu Ghraib as the most telling evidence that this war has unleashed uncontrollable emotions and irrational violence that are consistent with all war and that make waging war unjustifiable and unsustainable for the resolution of conflict by civilized humanity in the 21st century. We can--and must--find a better way.
