Using extensive materials from both published and private sources, this text focuses on US/Soviet diplomacy to explain the causes and consequences of the Cold War. It identifies major policy-makers and explores major crises in the post-1945 period. The author also looks at how the Cold War was shaped by domestic events in both the USA and Soviet Union. Material new to this edition includes: a rewritten post-1989 final chapter; the rewriting of the events in the 1950s, the Lyndon Johnson presidency and the Reagan presidential years; and a stronger focus on Soviet/Russian developments.
