The Power and Purpose of International Law

The Power and Purpose of International Law examines the fundamental role of international law in maintaining global order and promoting peace between nations. Through analysis of historical examples and legal frameworks, Mary Ellen O'Connell demonstrates how international law functions as a legitimate and effective system rather than merely a set of idealistic principles. O'Connell addresses key criticisms and challenges to international law, including arguments from realist scholars who question its authority and enforceability. The book presents evidence of international law's concrete impacts through case studies of armed conflicts, economic disputes, and environmental agreements. The work engages with complex theoretical debates while remaining accessible to readers outside the legal field. Through examination of post-9/11 policies and other contemporary issues, O'Connell illustrates the continued relevance of international legal frameworks in modern global affairs. This scholarly work speaks to enduring questions about power, justice and cooperation in an interconnected world. The analysis suggests that despite its limitations, international law remains essential for establishing shared norms and constraining state behavior.
