I'm asked this question all the time and I'm not sure how to respond. So, I'd like to ask the membership. How do we determine we have "won" in Iraq?

I tell them that it will be a gradual process and that we won't "win" in the classic military sense. That if we are successful the insurgency will lose it's momentum and slowly fizzle out. But I'm not able to come up with a satisfactory answer to the question, even for myself.

How do we know if we have "won?"
