An unusually timely book. The author, a well-respected and close observer of the SALT negotiations of the past decade while he was with RAND, writes with clarity and evenhandedness. Especially useful is his discussion of the institutional setting of the negotiating process in Washington and Moscow, including the use of the "back channels." Wolfe's careful history makes clear how the SALT II agreement is the direct descendant of the Vladivostok accord of 1974. Although some of the chapters were previously published as RAND papers, there are significant new materials covering the Carter Administration. Unlike much of the current debate, this is a valuable treatise rather than a tract.
