2. The fear of chemical weapons during the Gulf War accelerated the completion of the [Chemical Weapons Convention].
3. The [Chemical Weapons Convention] is designed to isolate nations that are determined to retain chemical weapons, and to deter acquisition of chemical weapons by other nations. Opponents like to criticize the convention for not doing more but no one has proposed a better vehicle for international action against a threat that cannot be controlled by any one nation alone. The convention is just one element, albeit a key one, in a complex strategy including national intelligence and potential counterforce, legitimized by the international norm that the convention upholds. Verification can never be perfect, but under the convention there will always be uncertainty in the mind of a potential proliferator as to whether a violation would be detected. This will deter some and force greater difficulty, expense and risk on those determined to violate the norm.
2. International treaties banning chemical weapons are of little use. A group of terrorists could produce enough toxic chemicals in a small laboratory to do significant damage in any of the countries that have officially banned the production.
