Answer
Besides Romania, Tismăneanu's work has focused on the Soviet Union. He has written several books on the history of the Soviet Union, including The Fall of Communism in Romania (1992) and Stalinism for All Seasons (2008). In his work on the Soviet Union, Tismăneanu has argued that the country's history is one of repression and violence, and that the Soviet system was inherently totalitarian.
