This book presents a systematic comparison of the military strategies pursued by five great powers, eight major middle powers and eight middle powers during the early twenty-first century.In addition to mapping the strategic priorities of these states, the study develops and applies a theoretical framework to explain differences and similarities in their strategic priorities. Moreover, the work evaluates how the stability of the present international system, and the US-led liberal international order (LIO), is affected by the strategies pursued by the US and other leading states. The book aims to contribute to previous research in three ways. First, it intervenes in the debate on the stability of the unipolar system and the US-led international order by offering a theoretical framework and an empirical approach for exploring and explaining the strategic priorities and defence strategies of different categories of states. Second, it aims to fill a void in research on strategy – the lack of a comparative and systematic approach to contemporary strategy that facilitates and guides systematic comparisons and analyses of the alignment and military strategies pursued by both major powers and less powerful states. Third, it provides an empirical contribution to the debate on the stability of the unipolar system and the US-led international order by presenting a documentation of the strategic priorities of 21 states based on primary sources, consisting of official documents such as national security and defence strategies and defence bills. In the conclusion, the authors summarise the empirical findings on the system level, the regional level and the unit level and present their overarching conclusions for the whole project.This book will be of much interest to students of military and strategic studies, defence studies, foreign policy and international relations in general.
