Book excerpt: From internal oppression in Burma to interstate conflict in the South China Sea, the people of Southeast Asia face a range of threats. This book identifies and explains the security challenges -- both traditional and nontraditional -- confronting the region. Collins addresses the full spectrum of security issues, discussing the impact of ethnic tensions and competing political ideologies, the evolving role of ASEAN, and Southeast Asia's interactions with key external actors (China, Japan, and the United States). The final section of the book explores how the region's security issues are reflected in two current cases: the South China Sea dispute and the war on terrorism.
