Did you see the (pretty young thing) Hong Kong reporter at the daily CENTCOM briefing asking Gen. Brooks where the US forces will retreat "if it comes to that?" He refused to consider the question.
I would suggest another answer: "We'll be leaving someday, Ma'am. Before we do, however, you'll be able to get on a tour bus in Baghdad and for a few bucks visit all of Saddam's bunkers, palaces, party headquarters, and torture chambers, or whatever is left of them."
