This textbook provides a coherent introduction to post-Cold War and post-9/11 military theory for upper-level students seeking an initial understanding of strategic studies. In the contemporary period there has been significant and growing interest among students about international security issues. While many publications focus on one particular aspect of military strategy, there is no single volume that provides a comprehensive yet accessible overview of strategic thought in this new era. Modern Military Strategy will fill this gap in the literature, with chapters on the conduct of war in each of the naval, land, air, space and cyber dimensions, and on nuclear strategy, and irregular war and counterinsurgency. The text concludes by identifying crosscutting trends, statements, and principles which may form the basis of a modern, general theory of war. This book will be essential reading for students of strategic studies, war studies and military history, and highly recommended for students of security studies and international relations in general.
