I don't mind having Powell at State with a moderating voice. And he has been a good soldier once a decision is made. He has been supportive of the war once the UN route was discarded. However, where I think Powell hurts us is his reliance on the old guard at Foggy Bottom, the Clintonites. Rumsfeld cleaned house at the Pentagon; Powell has left his intact, and they run around interfering with this war.
Powell did blab too much to Woodward.
He's too multilaterist for my tastes, but his input is valuable.
