I'll take it even further. I don't believe GW Bush was the real acting president of this country (at least in regard to foreign policy) until he finally made a stand. By firing Rumsfeld, GW decided to stand up to Cheney and declare to him and the world "now I am a man".

And of course it was Cheney's war. GW didn't know a Sunni from a Shiite, and Cheney was the Defense Sec. under Bush I. Besides, a lot of insiders have confirmed that very thing. Were you paying attention to details released at the Libby trial?
