This is a thorough and sophisticated study of one of the most critical current issues in world politics. Bruce Porter examines Soviet policy and behaviour in Third World conflicts in the postwar period, focusing particularly on five examples: the Yemeni civil war, the Nigerian civil war, the Yom Kippur war, the Angolan civil war, and the Ogaden war. Aiming to illuminate various complex tactical and operational aspects of the USSR's policy in local conflicts, the author draws on a wide and eclectic range of sources. He pays close attention to the Soviet role as arms supplier and diplomatic actor in relation to both US policy and the dynamics of the local conflict, and he concludes with a careful consideration of the effectiveness of Soviet policy and of the implications for the United States.
