Internal security is a crucial aspect of comprehensive national security, addressing not only external military threats but also internal conflicts that can undermine a state's integrity. Post-World War II, traditional security concerns were primarily external, with nations focused on military responses and deterrence. However, as the dynamics of conflict shifted, particularly for newly independent nations, internal security gained prominence, highlighting issues such as separatist movements and internal violence. This shift necessitates a broadened understanding of security, integrating not only military readiness but also socio-economic stability and political cohesiveness, thus emphasizing that a nation cannot be deemed secure if it experiences internal strife. Additionally, cooperative security measures and international frameworks are increasingly recognized as vital in addressing these multifaceted security challenges.
