Dick Polman has the goods, quoting what Petraeus wrote in the Washington Post six weeks before the 2004 presidential election:
I see tangible progress. Iraqi security elements are being rebuilt from the ground up. The institutions that oversee them are being reestablished from the top down. And Iraqi leaders are stepping forward, leading their country and their security forces courageously…There are reasons for optimism…Training is on track and increasing in capacity. Infrastructure is being repaired…Progress has also been made in police training…Considerable progress is also being made in the reconstruction and refurbishing of infrastructure for Iraq’s security forces…Iraq’s security forces are developing steadily and they are in the fight. Momentum has gathered in recent months. With strong Iraqi leaders out front and with continued coalition – and now NATO – support, this trend will continue.
That'll give us an idea of how much we can trust what we hear from him this September.
