Rumsfeld has already told Congress that the U.S. will use "pharmaceutical calmatives" (i.e. gas) on Iraqi civilians (http://www.moscowtimes.ru/stories/2003/02/21/120.html [Debbie: requires payment]), yet I am not aware of any mainstream media picking up on this story. This gas will be deployed using both an unmanned ‘loitering vehicle’ — which hovers in the air and sprays — and by mortar shell loaded with chemicals. But the use of any chemical weapon against people in wartime — no matter how supposedly nonlethal it might be — is expressly forbidden by a number of international treaties, all signed by the United States.
