Things to consider:
1. Satellite imagry and some scrap metal does not mean that we know the fate of an entire WMD project. The fact that Saddam's WMD infrastructure was dismantled and sent over the border does not mean that it was 'junked' per se.
1. Even if the equipment is now so much scrap, they wouldn't be in that state were it not for the threat of war. If they are in fact destroyed and hidden then it justifies our efforts the same as if they were found intact and hidden.
I agree. That weaponry which was found in a junk yard was of no danger to us after it was junked. That was what I was referring to and seems to be what the article references.
