Book excerpt: This book provides a comprehensive assessment of the global diffusion of the Revolution in Military Affairs (RMA) and its impact on military innovation trajectories in small states. Although the 'Revolution in Military Affairs' (RMA) concept has enjoyed significant academic attention, the varying paths and patterns of military innovation in divergent strategic settings have been overlooked. This book seeks to rectify this gap by addressing the broad puzzle of how the global diffusion of RMA-oriented military innovation – the process of international transmission, communication, and interaction of RMA-related military concepts, organizations, and technologies - has shaped the paths, patterns, and scope of military innovation of selected small states. In a reverse mode, how have selected small states influenced the conceptualization and transmission of the RMA theory, processes, and debate? Using Israel, Singapore and South Korea as case studies, this book argues that RMA-oriented military innovation paths in small states indicate predominantly evolutionary trajectory, albeit with a varying patterns resulting from the confluence of three sets of variables: (1) the level of strategic, organizational, and operational adaptability in responding to shifts in the geostrategic and regional security environment; (2) the ability to identify, anticipate, exploit, and sustain niche military innovation – select conceptual, organizational, and technological innovation intended to enhance the military’s ability to prepare for, fight, and win wars, and (3) strategic culture. While the book represents relevant empirical cases for testing the validity of the RMA diffusion hypotheses, from a policy-oriented perspective, this book argues that these case studies offer lessons learned in coping with the security and defence management challenges posed by military innovation in general. This book will be of much interest for students of military innovation, strategic studies, defence studies, Asian politics, Middle Eastern politics and security studies in general.
