Neoconservatism isn't dead; it can be renovated and returned to prominence, because, even today, it remains unrivaled as a guiding principle for U.S. foreign policy in the Middle East and beyond.
But neocons did have answers. We agreed on the need to address the root causes of terrorism, but for us that root cause was the political culture of the Middle East. Political culture did not mean Islam. Rather, it meant a habit of conducting politics by means of violence. At the time of the attacks, not one of the region's rulers (apart from Israel's) had been freely elected to his post.
Until someone comes up with better ideas than these, the neocon strategy of trying to transform the Middle East, however blemished, remains without alternative. No doubt, the results of the midterm elections will produce some course corrections (as Rumsfeld has discovered). But neocon ideas are unlikely to be jettisoned -- either by Bush or his successor -- until a viable replacement is found. So far, there is none.
