How will we know if we have won in Iraq?

Military historian Frederick Kagan, an enthusiastic supporter of the American effort in Iraq, has offered an interesting and thought-provoking way to define and measure success in this war. Kagan wrote:

"The president's nomination of generals David Petraeus and Raymond Odierno to take command of U.S. Central Command and Multinational Force-Iraq, respectively, was obviously the right decision. By experience and temperament and demonstrated success, both men are perfectly suited to these jobs. Given the political climate in Washington, however, their nominations are likely to be attacked with the same tired arguments war critics used to try to drown out reports of progress in Iraq during the recent Petraeus-Crocker hearings. So before the shouting begins again, let us consider in detail one of the most important of these arguments: that no one has offered any clear definition of success in Iraq."

"Virtually everyone who wants to win this war agrees: Success will have been achieved when Iraq is a stable, representative state that controls its own territory, is oriented toward the West, and is an ally in the struggle against militant Islamism, whether Sunni or Shia. This has been said over and over. Why won't war critics hear it? Is it because they reject the notion that such success is achievable and therefore see the definition as dishonest or delusional? Is it because George Bush has used versions of it and thus discredited it in the eyes of those who hate him? Or is it because it does not offer easily verifiable benchmarks to tell us whether or not we are succeeding? There could be other reasons--perhaps critics fear that even thinking about success or failure in Iraq will weaken their demand for an immediate "end to the war." Whatever the explanation for this tiresome deafness, here is one more attempt to flesh out what success in Iraq means and how we can evaluate progress toward it."
