Book excerpt: Analyzing regional challenges and their implications for U.S. foreign policy This book is an impressive overview of security and governance issues in South Asia and their implications for U.S. foreign policy in the region. The focus is on major enduring issues that include India-Pakistan relations, India-China relations, conventional forces, and nuclear weapons. The book's contributors also tackle a number of often underexplored issues, including democratic backsliding in India, authoritarian hardening in China, and the international ramifications of both. The impact of Pakistan's political culture on democracy, and the insurgency in Pakistan's Baluchistan province, along with examinations of the internal security challenges in Nepal, Bangladesh, and the Maldives provide lessons for other states on how to counterviolent extremism and insurgencies related to identity and marginalization. Anyone interested in South Asian security and U.S. policy toward the region will be rewarded with new insights on these topics, written by academics and analysts specializing in the issues. The chapter authors were close colleagues or advisees of long-time Brookings Institution senior fellow Stephen Philip Cohen. Cohen was the first American scholar to work on South Asian security studies. He largely defined the field, trained and mentored many of its leading analysts, and was himself its most experienced and insightful scholar-practitioner until his death in 2019. This book is dedicated to Cohen in recognition of his contributions to scholarship and policymaking on South Asia.
