February 8 , 2003 President Bush said in his weekly radio address : " We have sources that tell us that Saddam Hussein recently authorized Iraqi field commanders to use chemical weapons - - the very weapons the dictator tells us he does not have . Similarly , when the people of Halabja , or some of them , became guides for the Iranian forces that tried to breach the northeast [ front ] , the regime did not hesitate to use chemical weapons . It is essential that we take steps to prevent chemical substances from becoming environmental hazards . American and other Coalition forces in the Kuwait theater of operations ( KTO ) knew Iraq had the capability to use chemical weapons , so Scud missile attacks represented a significant cause for concern for anyone within their range . This is particularly true for the chemical industry , because deliberate or criminal efforts to trigger chemical releases are only one of many reasons a chemical release could threaten health and safety in a community ( as noted above , there are thousands of accidental and non - terrorist related spills and releases every year ) , and because safety improvements through hazard reduction must be the primary strategy for securing public health and safety from chemical releases related to terrorism . However , the following is an estimate of the influence of several factors which may have contributed to a decision not to use chemical weapons . It also described the threat of NBC terrorism , including the efforts of the Aum Shinrikyo cult in Japan , to disseminate chemical weapons . Furthermore , the Convention prohibits engagement in any military preparation to use chemical weapons or riot control agents as method of warfare . Hampton University , Hampton , VA , will receive a $ 139,994 grant for a 2-year research project to study chemical compounds that can absorb sulfur pollutants from the hot gases of advanced coal-based power plants .
