The book “National Security Beyond 2030: Navigating Sri Lanka’s Strategic Future in a Changing Regional and Global Order” provides a timely, forward-looking redefinition of what constitutes national security. It argues that traditional methods focused mainly on military strength and territorial defence are now inadequate for ensuring a country’s future. Instead, it promotes a broader, more integrated view of security that covers the protection of people, institutions, resources, and future potential. This wider perspective considers economic stability, social equity, and environmental sustainability, technological progress, and diplomatic foresight as key components of national resilience.
