This book develops new theory for superior strategy in complex warfare. The approach is comprehensive and practical, and it is applied to three contemporary security crises involving the United States, China, the Koreas, and Japan. Beginning with existing theories on strategy and culture, a new interpretation of "combined effects strategy" is introduced based on research and years of experience. Drawing from security theory and military doctrine, combined effects strategy is presented as a comprehensive process that subsumes the prevailing paradigm of combined arms. The entire book is written using the language of combined effects theory developed in the first chapter. Extensive use of symbols, text boxes, and charts orients the reader on combined effects in the three cases that follow. Unlike previous works, this study considers security culture as a way to understand warfare conceived and waged broadly: patterns of confrontation and cooperation, threat perception and assessment, and strategic effectiveness. Also for the first time, contemporary crises detail the interaction of strategies operating as lines of effect which when combined, create powerful synergies. A summary analysis of each case develops implications for future strategy. The concluding chapter is unique in its discussion of the influence of security culture on operational concepts, when lines of effect combine, and how security culture informs combined effects strategy, particularly for the United States. This is an important book for students, faculty, policy makers and practitioners with interests in strategy, global and US national security, defense policy, Asian regional security, Asian studies, military culture, military effectiveness, the future of warfare, and foreign policy. This book is in the Rapid Communications in Conflict and Security (RCCS) Series (General Editor: Geoffrey R.H. Burn).
