True enough, and therein lies the rub. Even household chemicals in proper combinations can be troublesome. Maybe they were using the DMS in its fabric softening capability ;^)
The quantities along with their apparent ownership(Ministry of Defense) might be pointing to something untoward, but it's a tough call IMO. Do we know if this stuff was more or less hidden or was if found in some old warehouse with a bunch of other "stuff"?

I do know that they can be used as weapons...I do know he used such weapons against his own people and the Iranians. He (Saddam) had a clear history in that regard.
As to whether the quantities, quality and state of this stuff warranted calling it a smoking gun...I can't say. Apparently our people thought not. But there was quite a bit of this type stuff found and it does have a dangerous military application.
