This is the first major scholarly study of the shift in Russian foreign policy toward ""peaceful coexistence."" To those who do not yet believe that position is more than a ploy, Gehlen's work will be a fine piece of evidence. The ideological foundation of the U.S.S.R. is his beginning and he argues convincingly that Lenin's view of world capitalism has become ameliorated by time and circumstance to the more mellow stance first taken by Khrushchev and carried on by his successors. The influence upon the Kremlin's policy makers by the military is then given close inspection and Gehlen defines what he sees as the essential conservatism of Russia's strategy since Stalin. From belligerence, she has turned to a full-scale program of ideological, political and economic contest with the United States. He outlines the use of these three perspectives in foreign aid, trade with neutral and Western nations and world political struggle. (Internal policy Gehlen sees as similar to foreign policy but does not deal with it at length.) In his final section, he describes the dynamics of the breakup of the Communist bloc and the Kremlin's response. A deep, close reading of the mechanics of change in contemporary Russian rule, Gehlen's book will be taken up for study by everyone in his field.
