The United States still faces no credible rival to challenge its supremacy, even after years of economic crisis and war. And yet, the very sources that give rise to its primacy - exceptionalism, the diffusion of power, and the involvement of civil society in the foreign policy process - also create vulnerabilities. The new third edition of U.S. Foreign Policy provides students with a concise and accessible overview of this foreign policy paradox, and highlights the challenges facing policy makers. Key updates include complete coverage of President Obama's first year in office, the administration's new emphasis on engagement, the ongoing wars in Iraq and Afghanistan, and the economic crisis. Students will also find a thorough review of the lessons of the Bush administration, including examinations of the rivalry between the State and Defense Departments, intelligence breakdowns, human rights controversies, and unilateralism. Instructors will appreciate the chapter organization, crisp writing, pedagogical features, and overall brevity that they have come to expect from this bestseller.
