In his address to the nation on Sept. 13, President George W. Bush singled out progress in Anbar Province as the model for U.S. success in Iraq.

The president's claims echoed those made earlier in the week by General David Petraeus, the top American commander in Iraq, in his congressional testimony. And they raised a question worth examining: Do U.S. military alliances with Sunni tribal leaders truly reflect a turning of hearts and minds away from Anbar's bitter anti-Americanism?

The data from our latest Iraq poll suggest not.
