Around the world, multiethnic 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 unwilling to respect the rights of the members of other groups, or to make sacrifices for them, and have no trust that any sacrifice they might make will be reciprocated.
Recent events show that where this sort of solidarity and trust is lacking, the consequences can be disastrous. In some countries, the result is violent civil war, as in Rwanda, Yugoslavia, and various parts of the former Soviet Union. In other countries, the state has dissolved in a more peaceful way, as in Czechoslovakia, albeit with significant economic and psychological costs. In yet other countries, particularly in Africa, the state has stayed together, but is little more than a shell, a loose confederation of more or less hostile groups who barely tolerate, let alone cooperate with, each other.
