If it were that simple.
My feeling is that Saddam is to meglomaniacal to go that route. He strikes me as more the, "I'm gonna die anyway, I might as well take you with me" type of guy...
My guess is he'll take the villa in Algiers over personal annihilation. But, you're correct that we can't count on that. The stakes are way too high for that. That is why we won't be confronting Saddam in Baghdad any time soon. Wouldn't be prudent. That will be left for the end of the campaign, once we are ready on the home front.
