India may have an implicit or unwritten National Security Strategy that is effectively implemented without the need for a formal written document.
The strategic objectives and priorities of national security may be well-defined and communicated through various channels such as policy speeches, government directives, and military doctrines.
Operational plans and strategies are constantly updated and adjusted based on the evolving security environment, without the necessity of a fixed written document.
The Chief of Defence Staff's statement indicates that while there may not be a single written document, there is a cohesive and coordinated approach to national security that is well understood and implemented across relevant institutions.
