Practicing the art of "net assessment," this weighty volume seeks to appraise the military balance between the two superpowers, bilaterally and in combination with their allies. The author, a retired military officer, is a defense specialist at the Library of Congress. He presents a massive compilation of facts and figures, juxtaposing military capabilities and trends, and touching on almost every aspect of the subject. Yet its very scope leads to a certain superficiality and one wishes for a more refined analysis. Nevertheless, military strategists and their armchair colleagues can use this generally accurate volume to their advantage.
