That's what everyone is assuming. It's Saddam's obvious move, to make it look like he's obeying the U.N. inspectors. And it would be incredibly idiotic for him to fail to do so.
And yet... It's conceivable that his own arrogance and enormous ego might do him in. Now that he's given an interview to Dan Rather, and explicitly refused to destroy the missiles (if in fact he was that clear about it in the interview), he'd look weak and afraid if he backed down. Saddam's precarious position depends upon his convincing his own people (especially his own generals) that obeying him is less deadly to their health than throwing in their lot with the Americans.
If Hussein has boxed himself in, and fails to destroy the missiles, that will finally give the rest of the Security Council the political cover it needs to cave into U.S. pressure. Even France might throw in the towel.
