Regional security refers to the measures and strategies that countries within a specific area take to ensure their safety and stability. This can involve military cooperation, intelligence sharing, and diplomatic efforts to address common threats, such as terrorism or territorial disputes. Organizations like the North Atlantic Treaty Organization (NATO) and the Association of Southeast Asian Nations (ASEAN) play significant roles in promoting regional security. Countries often engage in joint exercises and establish treaties to enhance their defense capabilities. Additionally, regional security can involve addressing economic issues, environmental challenges, and humanitarian crises that may affect stability. By working together, nations aim to create a safer environment for their citizens.
