The twenty-first century may not be the “Asian Century” after all. As China’s stock market crashes and its economy falters, as navies confront each other in the South China Sea, and as North Korea’s nuclear program casts its shadow, the world is waking up to the risks that threaten Asia’s future. International relations scholar and frequent media commentator Michael Auslin has long argued that far from being a cohesive powerhouse, Asia is a fractured region at risk of decline and instability. Here, he provides a comprehensive account of the economic, military, political, and demographic dangers that bedevil the region and argues that the United States is the only outside power that can help avert catastrophe. Bringing together firsthand observations and decades of research, Auslin’s “risk map” will be a must-read for investors, politicians, scholars, and manufacturers for years to come.
