It is not only the beginning of 2020 but also the opening of a new decade. Many important issues impacting India as a nation a decade earlier will develop at an accelerated pace in this decade and change our politics, economy and society dramatically. We need to think about how to survive in the fast changing global environment in which ethereal assets like data and ideas are likely to carry more power than hard assets. India will continue to face a complex set of challenges to its national security in the next decade. Without mitigating its security challenges and investing in human capital, India cannot hope to become a global power with innovative technological capability. Having been through several conflicts and crises, there is a growing recognition that India needs a robust national security system. It is therefore important now to imagine 2030. We need to think about what kinds of security challenges India will face and what kind of solutions can emerge in the future. This collection of essays analyses the contemporary security situation and evaluates possible alternative scenarios for the future for implementing India`s national security policy. Drawing upon the expertise of some leading practitioners and scholars in the field, the volume offers a broad array of timely and relevant analysis of an evolving and uncertain security environment to provide the reader with an informed and balanced overview of India`s national security.
