Analytical chemistry plays a role in the two strategies of defense against chemical or biological weapons that are discussed in this review: the detect-to-protect and the prevent-and-detect strategies. The detect-to-protect method, which is based on detection of a known chemical agent with a specific chemical sensor designed for said agent, has serious flaws. I argue that this approach should be replaced with the prevent-and-detect strategy. Such a change in the defense paradigm would require reallocation of resources, but it is necessary for effective protection of enclosed civilians from chemical and/or biological attack.
