Since the viewpoint throughout this closely argued volume is restricted to a consideration of what may have been the impact of the NATO Alliance on U.S. foreign policy and vice-versa, one cannot quite claim for the book the scope it really obtains in many sections, by inference and thorough documentation. It might be faulted for de-emphasizing the questions raised by attitudes recently adopted towards the Alliance by France, perhaps Belgium, and other members. Nevertheless this is as exhaustive and up-to-date a study of NATO's unique role in international relations as has so far been given. Comparisons of expectations and possible courses not taken with actual performance, and contrasting analyses of analogous treaty organizations such as the OAS and SEATO, are especially valuable.
