This book seeks to address emerging trends and developments when it comes to future warfare in East Asia. It will explore the likely future military domains, warfighting concepts, and subsequent military-technological priorities that could be the most critical in the next two decades. It considers what may constitute the next revolution in military affairs and when and how it might occur. Questions to consider include: (i) what is the role of new and emerging enabling technologies and their impact on warfighting in East Asia; (ii) what are the most likely kinds of armed conflict that we can expect in the next two decades; (iii) where is conflict most likely to occur; (iv) will armed conflict be more or less prevalent than now; and (v) what are the shocks or game-changers that can alter the route to the most likely future? How, then, might these long-term developments affect regional security and defence?
