According to her article, the vilas contained PHOSGENE, not Nerve agent.
Phosgene is MUSTARD GAS.
Mustard Gas is a WMD.
Do you have a link to where they said it was what?
I have no opinion on their believability - It's an anonymous UN official that said it, so they just might stretch the truth a bit.
The material — identified in inventory files as phosgene, a chemical substance used in World War I weapons — was discovered Aug. 24. It was only identified on Wednesday because it was marked simply with an inventory number, and officials had to check the many records in their vast archives, said Ewen Buchanan, a spokesman for the U.N. inspection agency."
The "phosgene" tag got put on it only by paperwork, not by looking at the contents.
Again, this is from AP, not like a reliable source.
At least this one is attributed:
Tests at a military facility in Maryland identified the substance as a nontoxic commercial solvent, said Paul J. Brown, deputy commissioner of the New York City Police Department.
Then again, it's CNN, so youse takes youse chances...
