The National Security Advisor: Shaping India’s Security and Foreign Policies

When India responds to a border crisis, negotiates a sensitive diplomatic deal, or weighs how to handle a hostile neighbour, one official sits at the centre of it all. The National Security Advisor (NSA) is the person the Prime Minister turns to first on matters of security and strategy. Yet for an office of such weight, the NSA holds no constitutional title and answers to no ministry. This post explains who the NSA is, how the role came into being, what it actually does, and why it has quietly become one of the most powerful positions in the government.

What the National Security Advisor does 🔗

The National Security Advisor is the chief adviser to the Prime Minister on national security and foreign affairs. The job is to give the Prime Minister a single, coordinated picture of the threats and opportunities the country faces, drawing together inputs that would otherwise be scattered across defence, diplomacy, intelligence, and home affairs.

This is harder than it sounds. India’s security machinery involves the armed forces, multiple intelligence agencies, the Ministry of External Affairs, the Ministry of Home Affairs, and several others. Each has its own priorities and its own information. The NSA’s task is to reconcile these differences, present the Prime Minister with clear policy options, and then oversee how decisions are carried out. According to an analysis by ORF America, the NSA has come to staff the Prime Minister on security engagements, settle disputes between bureaucratic agencies, manage the nuclear deterrent, and supervise implementation during crises.

The role is not limited to advice. The NSA is also the secretary of the National Security Council and heads its supporting secretariat, which makes the office both a thinker and an executor. It is the bridge between long-term strategic planning and day-to-day decisions.

How the office came into being 🔗

The NSA is a relatively young office. It was created in 1998 by the government of Prime Minister Atal Bihari Vajpayee, alongside the National Security Council itself. Before this, the functions now handled by the NSA were carried out by the Principal Secretary to the Prime Minister, with no dedicated structure for national security.

The timing was not accidental. 1998 was the year of the Pokhran-II nuclear tests, which made India a declared nuclear power and instantly raised the stakes of strategic decision-making. The first NSA, Brajesh Mishra, was a career diplomat who also served as Vajpayee’s Principal Secretary. Holding both jobs at once made him one of the most powerful officials the Prime Minister’s Office had ever seen, and he is credited with building the institutional structure for national security management from scratch.

The Kargil War as a turning point 🔗

If the nuclear tests created the office, the 1999 Kargil War cemented its importance. The conflict exposed serious gaps in how India gathered intelligence and coordinated its response. In its aftermath, the government set up the Kargil Review Committee, headed by the strategic affairs expert K. Subrahmanyam, to examine what had gone wrong.

The committee’s recommendations led to a major overhaul of India’s security architecture, including the establishment of the National Security Council Secretariat as a permanent body. This is the moment the NSA’s office moved from an experiment to a fixture. Interestingly, Subrahmanyam himself was openly critical in the early years, warning that the Council risked becoming a structure that existed only on paper.

The National Security Council and its three tiers 🔗

To understand the NSA, you have to understand the body it serves. The National Security Council (NSC) is the apex body for national security, chaired by the Prime Minister. Its core members include the Ministers of Defence, External Affairs, Home Affairs, and Finance, along with the Vice Chairman of NITI Aayog. The NSA serves as its secretary.

The NSC works through a three-tier structure, and the NSA is woven into each level.

The Strategic Policy Group 🔗

The Strategic Policy Group (SPG) is the first and most operational tier. It is the principal forum for inter-ministerial coordination. It brings together the Cabinet Secretary, the three service chiefs, the heads of the Intelligence Bureau and the Research and Analysis Wing, the Reserve Bank of India Governor, and key secretaries. Its main job is to turn broad strategy into actionable policy recommendations for the NSC. Since 2018, the NSA has chaired this group, placing the office at the heart of the decision-making machinery.

The National Security Advisory Board 🔗

The second tier, the National Security Advisory Board (NSAB), is the think tank of the system. Unlike the SPG, it is staffed by people from outside the government – retired officials, academics, and domain experts in fields like diplomacy, the military, economics, and science. Its purpose is to provide long-term, forward-looking analysis on emerging threats such as cyber warfare, space, and climate-linked security risks.

The advice the NSAB offers is non-binding, but it matters. By bringing in non-bureaucratic perspectives, it helps the government think beyond the immediate crisis. The board is reconstituted periodically, with its members appointed in consultation with the NSA and the Prime Minister’s Office.

The National Security Council Secretariat 🔗

The third tier, the National Security Council Secretariat (NSCS), is the permanent administrative engine. The NSA heads it directly, and it functions as part of the Prime Minister’s Office. The NSCS coordinates intelligence, defence, and diplomatic inputs, drafts strategic doctrines, and acts as the nerve centre of security decision-making. It is here that India’s first formal National Security Strategy has been taking shape.

Where security policy meets foreign policy 🔗

One of the most important things to grasp about the NSA is that the role does not stop at the border. Security and diplomacy are deeply intertwined, and the NSA operates in both worlds at once.

This is most visible in the NSA’s diplomatic assignments. As one analysis notes, the NSA has served as the Prime Minister’s Special Representative for boundary talks with China and as an envoy on security matters to neighbours like Pakistan and Israel. These are tasks that would traditionally belong to the foreign ministry, but they are handled by the NSA precisely because they sit at the junction of security and diplomacy.

The reason this matters is coherence. When the same official advises on both the military response to a threat and the diplomatic conversation around it, the two are far less likely to pull in opposite directions. The NSA’s office is designed to make sure that foreign policy and security policy reinforce each other rather than work at cross-purposes. A surgical strike, for example, has both a military dimension and a diplomatic one, and the NSA is positioned to weigh both together.

How powerful is the office? 🔗

The NSA holds no statutory office created by an Act of Parliament. The position rests on executive authority, and the Prime Minister appoints the NSA through the Appointments Committee of the Cabinet. Despite this informal footing, the office has accumulated remarkable influence.

A few features explain this. First, the intelligence agencies – the Research and Analysis Wing and the Intelligence Bureau – channel much of their reporting through the NSA. Second, amendments to the government’s rules of business have given the NSCS the power to generate Cabinet notes, access Cabinet papers, and join inter-ministerial consultations like any government department. Third, the personal rank attached to the office has been elevated over time.

The current NSA, Ajit Doval, holds the personal rank of a Cabinet Minister, a status first conferred in 2019. He is the longest-serving NSA in India’s history and is widely seen as central to the government’s security architecture. The tenure of the office is tied to the term of the Prime Minister, which underlines just how personal and trust-based the relationship is.

Recent restructuring 🔗

The office has continued to evolve. In 2024, the government for the first time filled the post of Additional NSA, promoting former R&AW chief Rajinder Khanna into the role, a position that had existed on paper but stayed vacant until then. New Deputy NSAs were also appointed to strengthen the team. These changes signal a deliberate effort to professionalise and expand the secretariat as India’s security challenges grow more complex.

The people who have held the office 🔗

The character of the NSA’s office has shifted with the backgrounds of those who held it. According to ORF America’s account, the five individuals appointed so far fall into two broad camps. Brajesh Mishra, J.N. Dixit, and Shivshankar Menon came from the Indian Foreign Service and brought a diplomatic sensibility to the role. M.K. Narayanan and Ajit Doval came from intelligence and policing backgrounds, and tended to focus more sharply on internal security.

This pattern reveals something important: the NSA’s emphasis depends partly on the individual. A diplomat-NSA may lean toward negotiation and external strategy, while an intelligence-NSA may prioritise counter-terrorism and internal threats. The office is shaped as much by the person as by the rulebook.

Why the NSA matters for India’s place in the world 🔗

India is one of the world’s largest economies and military spenders, and it sits in a tough neighbourhood with two nuclear-armed neighbours. Decisions about how to manage these relationships carry enormous consequences. The NSA is the official who pulls together the threads of intelligence, diplomacy, and defence into a single strategic view for the Prime Minister.

The office is not without criticism. The NSC has been faulted for meeting infrequently and for the opacity of its workings compared to its American counterpart. Some observers worry that concentrating so much influence in one unelected adviser sits uneasily within a parliamentary democracy. These are genuine debates about accountability and institutional design that are worth taking seriously.

Still, the trajectory is clear. From a structure that critics once said had barely “let off its first cry” after birth, the NSA’s office has grown into the coordinating hub of India’s strategic statecraft. As threats spread into newer domains like cyber and space, the demand for exactly this kind of integrated thinking is only likely to increase.

What do you think? Should an office as powerful as the NSA rest on executive authority alone, or would a statutory framework with greater parliamentary oversight strengthen India’s security decision-making? And does it make a difference whether the NSA comes from a diplomatic or an intelligence background?
