The moral case is, people say, "Oh they're not ready for democracy," but that's something someone who lives in a democracy would say about someone who doesn't live in a democracy. Well, if democracy is the highest form of human potential, then it can't be true for us and not for them. But, the practical case is democracies don't invade their neighbors. Democracies don't traffic in child soldiers. Democracies don't harbor terrorists as a state policy. So there's a reason to have more democratic states.
