this has been bugging me, where did the KNOWN supplies go?
Unless the UN lied to us when they counted the known supplies to begin with, they are still missing.
Who knows? The Hussein govt. claimed they destroyed the known stock of nerve gas following Gulf War I, but didn't document it or bother to follow any of the required inspection protocols. There have been a few binary chemical gas artillery rounds found with some of the gas (rounds they also weren't supposed to have had), but no large quantities. There was also a report out of Jordan of a foiled terrorist attack using poison gas. Allegedly, the terrorists were Syrian, but Syria has no reported manufacturing capability.
