International law permeates much of our daily lives. Its relevance transcends the regulation of relations between States and International Organizations and reaches us all, usually silently and invisibly. The challenge facing international law today, in this era of risk and globalization, is to build, on the foundations of national sovereignty and state rights, a new global ethic, based on human rights, the constitutional rule of law and international criminal law. This is a horizon that is already emerging: international law as the new ethics of globalization.
