Full access? That would be awesome. Prove he has nothing, and forget the war action. Only make plans to combat terrorism from then on.
Personally, this "war" is just going to crush the airlines, and if there is no need to attack, ala there is no weapons of mass destruction threat, so much the better. Plus I'd hate really hate to see American service men go in for any other reason than to crush weapons that could be labeled other than "mass destruction". His scud missiles, and their leading scientists missed Israel, a entire country, most of the time for Christ’s sake. They’re a sad military foe to say the least.
A guy like Saddam with his track record is pry just buying time though, as he will be just routed again and fears death. If he has them, he will do anything to stay alive.
