Banning Chemical Weapons is a readable account of the science and technology involved in attempting to achieve an enforceable international ban on chemical weapons. If such a ban is negotiated, it will be the first effective treaty of its kind, surpassing the Nuclear Non-Proliferation Treaty and the Biological Weapons Convention. The layman should have a grasp of the basic science of chemical warfare and defense to understand the intricacies of the negotiation and drafting of such a treaty. A successful and socially desirable treaty will have contributions from many quarters--from politicians, diplomats, jurists, and scientists.
