My duaghter is a Chemical specialist who spent 15 months in Iraq in 2004/5. While at Camp Victory they were mortared. The rounds used contained cyanide. They were "chemical" rounds. Fortunately, the idiots firing them were bad shots, the wind was wrong, and the rounds failed to detonate because they were improperly assembled.
Anybody remember hearing about that in the news?
The UN's and the media rules for being able to label something a WMD are ridiculous. It's like saying you are going to search a house for a gun. You go in, find 99% of the pieces and a few bullets hidden in various locations, but are not allowed to say you found a gun.
