The book on The Military’s Role in Internal Security explores the critical and often controversial involvement of armed forces in maintaining domestic stability. While the primary function of the military is to safeguard the nation’s borders against external threats, its role in ensuring internal security has become increasingly significant in contemporary times. This book delves into the complex dynamics between the military, law enforcement, and government authorities when dealing with internal security challenges, such as civil unrest, terrorism, insurgency, natural disasters, and other crises that may overwhelm civilian capacities. Drawing on historical and modern-day examples, the book examines how various nations have leveraged their military forces to respond to internal threats, particularly when national security is at stake. It analyzes the differences in military intervention across different political systems, with a focus on the implications for democratic governance and human rights. In democracies, military involvement in internal security is often subject to strict oversight and legal constraints, ensuring that civil liberties are not infringed upon. In contrast, authoritarian regimes tend to use the military more freely to suppress dissent, which raises significant ethical and legal concerns. Overall, The Military’s Role in Internal Security offers a comprehensive analysis of this important topic, providing a nuanced understanding of the military’s multifaceted function in domestic security and the implications of its growing involvement in non-traditional operations. It serves as an essential resource for policymakers, military leaders, scholars, and anyone interested in the intersection of defense and internal security in modern governance
