Whether it would happen turned on four great questions: Would East and West Germany be reunited; would Russia become a truly democratic, stable, nonimperial nation; what would happen to Yugoslavia, a cauldron of diverse ethnic provinces, which had been held together by the iron will of Marshal Tito; and would Russia and the former Communist countries be integrated into the European Union and the transatlantic NATO alliance with the United States and Canada?
