In the twenty-first century, the United States confronts an international system of great complexity and shifting security challenges. This book's relevance lies in its assessment of certain large-looming cases, including the possible acquisition and deployment of nuclear weapons by Iran and the continuing tensions created by North Korea's nuclear arsenal. The Obama 'pivot' of national security and defense emphasis to Asia reflects not only the growing economic importance of that region, but also the growing number of security dilemmas in a region that is already awash in nuclear forces. The management of nuclear crises and even the possible need to terminate nuclear wars before they expand beyond a single region are among the possible challenges facing future U.S. and allied policy makers and military leaders.
