Global chaos arises from the growth of populism into nationalism, yielding empires based on power and surging trade protectionism. This shows that human democracy has deteriorated and is not as good as Athenian democracy was 2000 years ago. Humanity must adopt the principles of humanism, constitutionalism, internationalism and natural law, and strive to achieve One World under One Set of Laws in order to achieve world peace. See the Charter for Permanent Peace and Development.
