Around the world, multi-ethnic states are in trouble. Many have proven unable to create or sustain any sense of solidarity across ethnic lines. The members of one ethnic group are indifferent to the rights and interests of the members of other groups, and are unwilling to make sacrifices for them. Moreover, they have no trust that any sacrifice they might make will be reciprocated. Recent events in Eastern Europe and the former Soviet Union show that where this sort of solidarity and trust is lacking, demands for secession are likely to arise.
