For many years, but particularly since September 11, 2001, international law and international relations have had a major impact on every American, whether the issue is terrorism; the use of force by the United States and its allies; addressing climate change or mitigating world poverty. This course on public international law will provide an introduction to such subjects as treaties and other sources of international law; international law in the United States; principal international organizations; concepts of sovereignty, statehood and territoriality; the bases for jurisdiction; state responsibility; and international law and the use of force. It will explore international human rights, international environmental law and international economic law.
