Wars and conflicts have become a near constant presence today, brought to us on a real-time basis on myriad communication devices. A cursory scan of recent conflicts reveals the blurring lines between war and peace, state versus non-state, regular and irregular, and conventional vis-à-vis unconventional. Over the past decade or so, the prevailing security environment in many regions has changed radically. Simultaneously the probability of conventional conflict between states or groups of states has steadily declined while sub-conventional conflict has gained prominence. These small, niggling wars have been termed as hybrid, non-linear, grey zone, or unrestricted, among others. It thus becomes necessary to enquire ontologically and epistemologically into these terms to understand if they allude to the same phenomenon through different frames. Furthermore, are these an aberration or, increasingly, the convention? This book tries to address this crucial research gap related to the changing character of conflicts in the strategic discourse in India.
