How International Law Works presents a comprehensive and current discussion of international law, reflecting its growing importance on the world stage and demonstrating its increasing impact on domestic decision making. In recent years, appeals to international law have become increasingly relevant to the world of international relations. Video piracy in China, global warming, and the US involvement in Iraq-all have generated considerable international law claims, and they point toward a broader sea change. Now, a vast range of issues that had previously fallen under domestic control-intellectual property, environmental policy, investment rules, health and safety regulations, to name a few-are now subject to international legal obligations. Andrew T. Guzman's How International Works considers this vast range of issues, and ultimately provides a thoroughgoing guide to the complexities of international law.
