Bombs are made of metal. Do you think a sanction-starved country like Iraq is going to leave a pile of cut-up bombs laying around for inspectors to look at? Likely they'd do something like turnthem into cook-pots or something. With something like this, where do you get evidence that it's gone? The only proof is to find bombs that might be cookpots(or whatever). That's where the inspectors come in. If they find bombs, we're right. Questions? Comments?
They got plans for the Polaris Missile on the internet, and have forged exact working copies of them from that junk, and are assembling them in mobile labs. Duck and Cover!
