Barry R. Posen explores how military doctrine takes shape and the role it plays in grand strategy-that collection of military, economic, and political means and ends with which a state attempts to achieve security. Posen isolates three crucial elements of a given strategic doctrine: its offensive, defensive, or deterrent characteristics, its integration of military resources with political aims, and the degree of military or operational innovation it contains. He then examines these components of doctrine from the perspectives of organization theory and balance of power theory, taking into account the influence of technology and geography. Looking at interwar France, Britain, and Germany, Posen challenges each theory to explain the German Blitzkrieg, the British air defense system, and the French Army's defensive doctrine often associated with the Maginot Line. This rigorous comparative study, in which the balance of power theory emerges as the more useful, not only allows us to discover important implications for the study of national strategy today, but also serves to sharpen our understanding of the origins of World War II.

This paper focuses on the formulation of doctrine since World War II. In no comparable period in history have the dimensions of the battlefield been so altered by rapid technological changes. The need for the tactical doctrines of the Army to remain correspondingly abreast of these changes is thus more pressing than ever before. Future conflicts are not likely to develop in the leisurely fashions of the past where tactical doctrines could be refined on the battlefield itself. It is, therefore, imperative that we apprehend future problems with as much accuracy as possible. One means of doing so is to pay particular attention to the business of how the Army's doctrine has developed historically, with a view to improving methods of future development.

This book puts military doctrine into a wider perspective, drawing on military history, philosophy, and political science. Military doctrines are institutional beliefs about what works in war; given the trauma of 9/11 and the ensuing 'War on Terror', serious divergences over what the message of the 'new' military doctrine ought to be were expected around the world. However, such questions are often drowned in ferocious meta-doctrinal disagreements. What is a doctrine, after all? This book provides a theoretical understanding of such questions. Divided into three parts, the author investigates the historical roots of military doctrine and explores its growth and expansion until the present day, and goes on to analyse the main characteristics of a military doctrine. Using a multidisciplinary approach, the book concludes that doctrine can be utilized in three key ways: as a tool of command, as a tool of change, and as a tool of education. This book will be of much interest to students of military studies, civil-military relations, strategic studies, and war studies, as well as to students in professional military education.

In this sobering book, Barry R. Posen demonstrates how the interplay between conventional military operations and nuclear forces could, in conflicts among states armed with both conventional and nuclear weaponry, inadvertently produce pressures for nuclear escalation. Knowledge of these hidden pressures, he believes, may help some future decision maker avoid catastrophe.Building a formidable argument that moves with cumulative force, he details the way in which escalation could occur not by mindless accident, or by deliberate preference for nuclear escalation, but rather as a natural accompaniment of land, naval, or air warfare at the conventional level. Posen bases his analysis on an empirical study of the east-west military competition in Europe during the 1980s, using a conceptual framework drawn from international relations theory, organization theory, and strategic theory.The lessons of his book, however, go well beyond the east-west competition. Since his observations are relevant to all military competitions between states armed with both conventional and nuclear weaponry, his book speaks to some of the problems that attend the proliferation of nuclear weapons in longstanding regional conflicts. Optimism that small and medium nuclear powers can easily achieve "stable" nuclear balances is, he believes, unwarranted.
