losing patience?

John McCain and Russ Feingold join the ranks of US officials telling the Iraqis the US is "losing patience" and urging them to form a unity government soon.

Isn't that also just a nifty signal to the insurgents that despite de facto President Bush's rhetoric, we are in fact getting ready to cut and run? Is the de facto Admnistration at the stage where it's looking for something positive so it can declare victory and bug out?
