Not so many years ago, when “de-Stalinization” and “de-satellization” seemed to be the order of things, the horizons of change in Eastern Europe appeared virtually unlimited. Indeed, one elaborate political science treatise, published in 1967, purported to discern two “irreversible trends” throughout the area, an increase in pluralization within individual countries and the tendency of the European Communist states to become more European and less Communist. Nowadays, in the continued aftermath of the massive Soviet intervention to reverse the changes actually undertaken during 1968 in Czechoslovakia, such certainties have all but disappeared. Yet, as Professor Korbonski’s timely and stimulating discussion reminds us, there is no logical reason to suppose that Communist societies are immune to change. With respect to Eastern Europe, however, as Professor Korbonski also notes, the hazards of forecasting are truly, formidable.
