You DON'T KNOW?!?!?

He really doesn't;

Senator John Warner (R-Virginia): "Do you feel that [Iraq war] is making America safer"?
Petraeus: "I believe this is indeed the best course of action to achieve our objectives in Iraq."
Warner: "Does the [Iraq war] make America safer?"
Petraeus: "I don't know, actually. I have not sat down and sorted in my own mind."

Well by all means General, why don't you sit down and sort it out instead of blindly follow the Chimp in Chief.
