"The question concerning the role of the state in preserving territorial integrity is raised by the recent events in the former Soviet Union and former Yugoslavia: why do some multinational states survive the collapse of the authoritarian regime while others do not? Except in Spain, democratization occurred until recently in countries where the integrity of the state was not problematic. The breakup of the Soviet Union, Yugoslavia, and Czechoslovakia raises a new set of issues because there democratization unleashed movements for national independence; indeed, for some political forces, democratization is synonymous with national self-determination and the breakdown of the multinational state that was maintained by authoritarian rule. Under such conditions, Hobbes's first problem - how to avoid being killed by others - is logically and historically prior to his second problem - how to prevent people within the same community from killing one another."
