A huge added complication to the job of taking out Saddam is that his sleepers could strike anywhere. For example, suppose we put in the appropriate civil defense infrastructure to contain the threat in the most obvious, high-value, high vulnerability targets, e.g. high-tech aerosol detectors in the NYC and DC subways, millions of doses of anthrax vaccine, and distribution channels for treating millions of people in the space of 24 hours. Even if we can do that, Saddam could always threaten massive casualties in less-defended cities of the US or of our allies. And, believe me, if his back's against the wall, he'll do anything that stands a chance of working. This is another reason why I think a realistic timescale for removing Saddam is years, not months.
