Book excerpt: The Soviet Union and Cold War Neutrality and Nonalignment in Europe examines how the neutral European countries and the Soviet Union interacted after World War II. Amid the Cold War division of Europe into Western and Eastern blocs, several long-time neutral countries abandoned neutrality and joined NATO. Other countries remained neutral but were still perceived as a threat to the Soviet Union’s sphere of influence. Based on extensive archival research, this volume offers state-of-the-art essays about relations between Europe’s neutral states and the Soviet Union during the Cold War and how these relations were perceived by other powers.
