Subtitled ""A Study of Soviet Foreign Policy,"" this is yet another in the extensive Praeger series of studies in Sovietology, notable for their comprehension and clarity. No new ground has been covered here, but the author, in his review of the political history of Communist Russia, has managed to place several crucial current questions in clear perspective, notably the Sino-Soviet split. The emphasis is upon relations between Russia and her more immediate satellites, with the various policies pursued in Poland and Hungary and the failures in Yugoslavia and Albania receiving special attention, but the larger context, including her aspirations in the Far East and Africa are also noted. As a survey of the Cold War era, the over-all picture is an optimistic one from the Western point of view, in that the setbacks the USSR has suffered are made much of, without comparison to US mistakes. The final section, ""The Unsteady Monolith,"" particularly stresses this interpretation. A readable presentation.
