This book examines the evolving concept of national security and how human systems could be governed in an ever turbulent and dynamic world. It takes a revised look at the concept of national security, previously researched and identified by the author, based on the present context but with a futuristic appreciation of governance, primarily national but extended to global perspectives, in the modern and dynamically shifting world. The book emphasises the need for governments to maximise national security for the well-being of their people. The concept of national security is taken as the key subject of national governance which is extendable to global governance wherein national security is not only the physical or military security alone but also the overall well-being of the people of a nation. This book explores how national security can be achieved by balancing its various elements in different terrains where the game of governance is played in national as well as global perspective. It also presents additional findings and observations to show that the approach is transformative, redefining the key knowledge paradigms. This book is relevant for policy makers, students, researchers and academics who wish to explore and rethink their approach towards governing the human systems, whose well-being is the responsibility of governments.
