Maybe we'll now see whether Saddam actually has any Weapons of Mass Destruction at his disposal? If he doesn't unleash them do you think Bush and Blair will apologise?

Problem is, it isn't necessary for the WMDs to be in Iraq now for the US and UK to "find" them there, or even for them to get "used" there. Remember, the US and UK have already set themselves up to do pretty much anything they want to by floating rumours that Iraqi soldiers have obtained US and UK military uniforms. So no matter what the US and UK do there, they can blame it all on Saddam's forces.

Metchosin, here's Chapter VII of the United Nations Charter, "Action with respect to threats to the peace, breaches of the peace, and acts of aggression"
