Maybe there are chemical weapons in Iraq

And maybe the US military is the one using them:

FALLUJAH, November 10 (IslamOnline.net & News Agencies) - US troops are reportedly using chemical weapons and poisonous gas in its large-scale offensive on the Iraqi resistance bastion of Fallujah, a grim reminder of Saddam Hussein’s alleged gassing of the Kurds in 1988.

I have no idea if that is a reliable source. I do know that the US military is not.
