...So?
Unless they found something in that "other" warhead, this means nothing. I have an empty gas lighter in my house. Now, am I an arsonist, or a smoker?
It's no news that he had MDWs. And, undoubetdly, Saddam's going to claim this was from back then. There's no real way to prove to the contrary, unless it's a new model or something.
At any rate, Bush is gonna invade anyway- there's absolutely no question of that. You're waving goodbye long after the cowboy has ridden into the sunset, gone on to marry, settle down, have kids, get a job as an investment banker, suffer a stroke, die, and decay into dust. The only question remaining in the Iraq deal is whether a revolution forms, and Bush helps it along, or whether he just has the Army go in and kill everybody in sight.
EDIT: And it doesn't necessarily violate the disclosure, if there's nothing in them. Spent bullet casings and evacuated shells do not qualify as munitions, no matter how crazy or gung-ho warmongering you are.
