Two examples of "new thinking" in the West inspired by that of Mikhail Gorbachev and the sea-changes in the political map of Europe. Both books combine recital of recent events, notably in the Soviet Union and eastern Europe, with thoughts on how the problems of security, economics and international organizations have been or may be transformed. Neither has a specific overriding message-the individual authors are on their own-except perhaps the need to think historically and boldly. In the volume edited by Clark and Serfaty, Josef Joffe has a particularly penetrating essay on Germany and Russia, the two "revisionist" powers.
