Tony Cordesman has become a veritable institution among Washington policy analysts. Few are more prolific, especially in the area of comparative analysis of weapons systems. He can be depended on to produce data-rich, comprehensive, lavishly documented studies of military doctrine and usage, intentions to acquire or produce weapons systems, and willingness to abide by international arms-control regimes. These two books are no exception. They include indepth analyses of conventional and non-conventional weapons systems. It is the latter that makes these books so important to analysts of regional weapons development and arms control. Cordesman examines Iraqi and Iranian acquisitions, from purchase, absorption, production, and use of conventional weapons to efforts to acquire nuclear, biological, and chemical weapons—the so-called weapons of mass destruction—and the requisite ballistic-missile–delivery systems.
