India’s Security Trilemma : Nuclear Deterrence, Multi Domain Warfare and Resource Leverage for understanding the complexities of India’s present security landscape. Integrating operational experience with strategic insight, the book explores the convergence of nuclear deterrence, sub-conventional warfare, and multi-domain conflict within the context of an enduring two-front challenge. Moving beyond conventional and static deterrence theories, it proposes a context-driven perspective to explain why crises in South Asia often unfold unpredictably across multiple domains and escalation thresholds. Drawing upon practical field experience and rigorous academic analysis, the work examines escalation patterns, doctrinal imbalances, and the influence of emerging technologies on modern warfare. It also offers actionable approaches for calibrated response, escalation management, and the promotion of strategic stability. Timely, insightful, and intellectually engaging, this book is an indispensable resource for policymakers, defence professionals, and scholars aiming to understand India’s changing security environment with strategic clarity and foresight.
