India's Supply Chains in a World at War goes beyond traditional discussions of logistics and trade. It is a sweeping exploration of how war, economics, and civilizational power intersect in shaping the global order.While supply chains are often seen as mere conduits of commerce, this book reveals their deeper role as instruments of influence and survival in an era where empires, not nations, define the world's balance of power. From semiconductors and metals to fertilizers, pharmaceuticals, and artificial intelligence, each chapter examines how the four great powers i.e. India, the United States, China, and Russia vie for strategic control of the world's most critical resources.Set against the turbulent backdrop of post-COVID geopolitics, the Russia-Ukraine conflict, and renewed tensions in West Asia, the book argues that the global focus has shifted from efficiency to resilience. Supply chains are no longer just about being "just in time," but "just in case."Rich in historical insight and geopolitical foresight, this book is an essential read for policymakers, business leaders, scholars, and all who wish to understand India's place in a rapidly re-emerging world of empires where economics, strategy, and civilization converge.
