This book offers a comprehensive analysis of the evolution of US naval presence and strategy in one of the world's most strategically significant regions. Spanning from the Cold War era to the present day, the book traces the trajectory of US engagement in the Indian Ocean, examining the factors driving strategic shifts, security challenges, and evolving alliances. It investigates how the US has transitioned from a posture of dominance to one of diffusion, engaging with regional partners to address emerging threats and seize opportunities. The book also looks at the rise of China and how it has impacted US presence in a somewhat transformed region – the Indo-Pacific. Part of the International Politics in the Age of Disruption series, the book will be indispensable for students and researchers of military studies, security studies, political studies, international relations, security studies, and South Asian studies.
