This slim monograph is densely packed with information about the nuclear capability and potential of Russia, Belarus, Ukraine, and Kazakhstan. It is an excellent compilation of data not only about nuclear weapons but also facilities such as reactors and research centers. In addition, the authors give detailed accounts of each country's status with regard to various international treaties and agreements. Twenty pages of news clips about illicit exports from the newly independent states are a chillingly concise and complete list of unsettling incidents over the last year. Four simple but well-drawn maps illustrate the location of the facilities and weapons. All in all, a wonderfully compact and informative reference work, up to date as of December 1994.
