AMERICAN FOREIGN POLICY is the market leader for the American foreign policy course. Guiding students through 21st century American foreign policy by placing contemporary issues, debates, challenges, and opportunities in their historic context, this text helps students understand and assess the forces underlying continuity and change. This Sixth Edition retains the book's effective analytical framework. Harnessing the conceptual, theoretical, and historical components that facilitate analysis of American foreign policy, the text maintains that five sources--international, societal, governmental, role, and individual--collectively influence decisions about foreign policy goals and the means chosen to realize them. Readers will come away from this text with knowledge of how the enduring principles, values and interests of the United States (peace and prosperity, stability and security, democracy and defense) define and reinforce the ability of policymakers to respond to changes in the international environment.
