This book provides a rich analysis of the actors and organizations to reflect on the antecedents and trajectories of terrorism and insurgency in South Asia, and the different countermeasures adopted by the countries to deal with the security and developmental challenges. South Asia is a complex geography that has been both a victim and a playing field for indigenous insurgencies, and domestic and transnational terrorist movements. The contributors to this volume explore how this situation has posed serious challenges to the sovereignty of the states, to national and human security, and to the socioeconomic fabric of the communities, and to the ethnic and religious cohesion. The book provides detailed studies of country cases on terrorism, security, and insurgencies, and it underlines the national, regional, and global implications of the threats that emanate from this region. Presenting an opportunity to diversify away from a Western-centric focus on terrorism and security, this book will be valuable to researchers in political science, criminology, defense and security studies, and to policy makers and think tanks.
