The failure of the United States to achieve a decisive victory in Iraq would have substantial consequences. The deaths of Qusai and Odai Hussein last week reflect the American belief that decapitating the guerrilla movement might be decisive. So far, the tempo of operations by the guerrillas has not declined, but that means nothing yet; it might take time for the effect of the two deaths to ripple through the system. Nevertheless, it is possible that the Hussein brothers were not critical to guerrilla operations. Indeed, it is possible that those operations are designed to continue without centralized leadership. Bringing the guerrillas under control could be a daunting task, but the current disarray within the Bush administration makes it much harder to achieve.
