Available in English for the first time, this collection of historical essays by Pierre Broué sheds light on the role of the opposition to Stalin within Russia during World War II and explores the development of the Fourth International, a communist organization that opposes capitalism and Stalinism, led by Leon Trotsky during the 1940s. A biographical sketch of Broué by Vincent Presumey paints a substantial, frank, and illuminating portrait of a unique historian and political analyst.
