Perestroika, which means restructuring, is Mikhail Gorbachev's own account of the revolution he is presently implementing in the U.S.S.R. Seventy years after the October Revolution, it constitutes real changes in attitudes, in ideas and in practice that entail a radical alteration of both domestic and foreign policy. Perestroika is the next stage in socialist history, when greater responsibility is delegated to the people, and initiative, openness and a spirit of emulation are strongly encouraged through a real sense of personal involvement. It is an unprecedented blueprint for change that can only have profound implications for the world.
