In some respects Professor Gati's volume sets a new standard in the study of Soviet policy and Eastern Europe. He has explored many little known sources in order to get behind the facade of Soviet and Hungarian official positions, and of those on the Western side as well. A notable contribution is his exposition of the interplay between internal competition and uncertainty in the Kremlin and changes in the leadership and policies of the East European parties and states, in this case the Hungarian, from the end of World War II to the present. The book, however, goes well beyond Hungary to treat developments throughout Eastern Europe and to consider both Soviet and American policy toward that area. The author makes much of his differences with the usual interpretations of Western analysis, slaying a number of straw dragons as he goes; in any case, it is a stimulating book that breaks new ground and merits a wide reading.
