Unless I'm mistaken, New York Mayor Rudy Giuliani's main point here is that he thinks we should continue the surge if and only if he thinks we should continue the surge. Does he think we should continue? Well, he couldn't say. But he definitely will do the thing that he thinks he should do, whatever that is. Possibly. Also: He'll keep the country on offense. Fortunately, we have David Frum's word for it that vague and evasive though Rudy may be, he's less silly than Mitt Romney.
