Of course there is. The fact is that these missiles were previously tagged by the Richard Butler UN inspectors who did not get a chance to destroy them before being kicked out in 1998. If they were NOT there, this would be mean the inspectors had actually found something, since then the mustard would be in an unauthorized place unknown.
Get it? The UN inspectors are going to the the exact places where they are least likely to find anything untowards -- places the Iraqis know they are going to, like those palaces. The real stuff is disbursed in hidden locations almost impossible to find except perhaps through interviews with defectors. Instead the UN will interview in-country Iraqi engineers who face torture if they spill the beans.
What happenned? Last night, most posters here seemed to understand that the UN inspectors are there to protect their dream of world government. Tonight posters (not Theo, I think) actually believe in the inspection regime. Unbelieveable.
Just destroy the mustard shells and be done with it (I understand that there wasn't time to oversee the destruction before).
