In Between Threats and War: U.S. Discrete Military Operations in the Post-Cold War World, author Micah Zenko presents a new concept to capture and illuminate the phenomenon: "Discrete Military Operations." "This book is readable, relevant, and insightful. It represents exceptional analysis on a topic that few have explored in such detail. It is well researched, well documented, and well organized. I recommend it to all civilian and military leaders pondering the utility and efficacy of direct military strikes against sensitive targets."
