In this section, we explore the concept of security and the sources of threats that challenge it. Security can be broadly categorized into traditional and non-traditional frameworks. Traditional security focuses mainly on military threats from external forces, aiming to protect a state’s sovereignty, independence, and territorial integrity. In contrast, non-traditional security encompasses a wider range of threats, including those arising from economic, environmental, and health-related issues. This broader perspective acknowledges that threats such as global terrorism, infectious diseases, and climate change are increasingly critical in determining the security landscape. The section emphasizes real-world implications of security strategies, noting how cooperation among nations is vital for addressing shared threats in an interconnected world. As we analyze the historical contexts of these threats, significant trends such as the rise in civil wars and internal conflicts, particularly in developing countries, highlight the urgency of these discussions.
