This new edition is revised, updated and expanded with new material on areas such as the KGB and spying, and the contribution of intelligence to Stalin's picture of the world. The new introduction looks at our perceptions of the Cold War, the various approaches that have been adopted for reviewing the Cold War and the difficulties of developing a theory of the Cold War. The book incorporates the most recent scholarship, theories and newly-released information to provide students with an invaluable introduction to the subject.
