Debuting in its first edition, American Foreign Policy in a New Era takes the contemporary challenges of globalization and hyper-partisanship as its starting point, and surveys how foreign policy is made and to what ends. This brief text is not only a review of theory, history, actors, institutions, and key policies but also an examination of how policymakers are affected by domestic and international political factors. Telling a uniquely engaging story of how foreign policy is made, American Foreign Policy in a New Era help readers understand the changing leadership role of the United States and the effect of world politics on the everyday life of Americans.
