This highly ambitious book unpacks the single biggest foreign policy question of the post-9/11 era--the nature of intrastate conflict. Clearly motivated by a desire to better understand the wars fought by the United States and to improve foreign policy, this book is a must-read for the US military. It will land on undergraduate and graduate course syllabi, win awards, and be discussed outside of academia.--Dan Reiter, author of How Wars End Skryť popis
