How the World Works: A Brief Survey of International Relations (2nd Edition)

How the World Works builds on students’ instincts about current world events and develops them into a more systematic and enduring understanding.  This brief text introduces each of the field’s major theories and demonstrates how different conceptual tools are used to interpret patterns in international relations. How the World Works not only grounds students in the essentials of international relations but also helps students use them to see past the headlines.
