India’s National Security Policy

Understanding National Security

National security refers to the capacity of a state to protect its territory, people, institutions and core values from internal and external threats. For a large, diverse and strategically located country, security is not merely the absence of war but the ability to preserve autonomy of decision-making and create a stable environment for development.

The security policy of the country has been shaped by three enduring influences: the politico-strategic setup inherited at independence, the colonial administrative and military heritage, and the deep imprint of Partition, which converted a civilizational frontier into a live and militarised border.

The formative years bore the strong stamp of the first Prime Minister, whose worldview blended idealism with a cautious realism.

▸ The Concept of National Interest

Security policy flows from a prior idea — national interest. The term emerged in the sixteenth and seventeenth centuries alongside the rise of the nation-state, replacing older notions such as the ‘will of the Prince’ with the language of vital interests. Its power lay in its ability to mobilise public will.

In the ancient world the fusion of politics and metaphysics, and in medieval times the feudal order, prevented the concept from crystallising.

For India, national interest is anchored in self-preservation — the welfare of its people, the protection of its political beliefs and way of life, and above all the maintenance of territorial integrity. Even today there is no universally agreed definition of the term, which makes the crafting of a coherent doctrine a matter of political judgement rather than mere technique.

▸ Determinants of India’s Security Policy

Significance of a Coherent Security Policy

• Guardian of sovereignty: a dominant, credible defence force is the precondition for preserving territorial integrity against conventional and sub-conventional threats.
• Enabler of development: persistent conventional and sub-conventional threats slow economic growth; security provides the stable environment in which growth can occur.
• Deterrence and dialogue: a clear posture signals resolve to adversaries while preserving diplomatic space for engagement, reducing the risk of miscalculation.
• Foundation of strategic autonomy: security capability underwrites India’s ability to take independent positions in a contested global order.
• Regional stabiliser: it positions the country to act as a net security provider for its wider neighbourhood, from West Asia to South-East Asia.

The External Threat Environment

▸ Pakistan — Asymmetric War and Limited Conflict

Pakistan has been the most persistent external challenge. The two neighbours have fought four wars (1947–48, 1965, 1971 and the 1999 Kargil conflict). Since acquiring nuclear weapons, the likelihood of an all-out conventional war has diminished, because both sides are nuclear-armed.

In its place Pakistan has pursued asymmetric warfare in Kashmir since the 1980s, using terrorist proxies to bleed India below the threshold of open war.

The instrument of choice has been limited incursions — the Kargil War of 1999 being the classic case. Despite grave provocations such as the 2001 Parliament attack and the 2008 Mumbai attacks, the country’s basic doctrine has been to keep channels of dialogue open. This rapprochement, however, has repeatedly been derailed by fresh attacks.

A cluster of strikes on security installations — the Pathankot air base (January 2016), Pampore (June 2016) and Uri (September 2016) — stalled talks.

After Uri, the response widened: cancellation of dialogue, a decision to diplomatically isolate Pakistan, use of the UN General Assembly to brand it a sponsor of terrorism and a destabiliser of South Asia, raising of human-rights violations in Balochistan, and refusal to attend the SAARC summit.

The strategic asymmetry itself breeds insecurity in the Pakistani military, which is unable to match India’s conventional strength and therefore leans on terror proxies such as Jaish-e-Mohammed (JeM) and Lashkar-e-Taiba (LeT).

Pakistan has signalled that any Indian conventional attack could invite nuclear escalation, which is why India invests in ballistic missile defence to guard against such escalation.

▸ China — The Second External Threat

China is widely recognised as the second external threat. Relations were cordial in the early years, but the 1962 war transformed the equation. In 1963, Pakistan ceded a slice of Pakistan-occupied Kashmir to China, giving birth to a Sino–Pakistan axis. China’s nuclear tests from 1964 added a further dimension. The boundary question remains unresolved to this day.

The undemarcated Line of Actual Control (LAC), roughly 3,488 km long, is the fault line; the 2020 Galwan Valley clash was its bloodiest recent flashpoint, followed by a prolonged stand-off in eastern Ladakh with both sides massing tens of thousands of troops.

China continues probing operations, presses claims over Arunachal Pradesh (‘South Tibet’), objects to India’s stance on the Dalai Lama, and refuses to reconcile India’s status as a nuclear-weapon state.

China deepens its footprint through the Belt and Road Initiative (BRI) and the String of Pearls — a network of ports and facilities ringing the Indian Ocean. The China–Pakistan Economic Corridor (CPEC), running through Pakistan-occupied Kashmir, violates Indian sovereignty and raises the spectre of a two-front conflict.

Instrument	Strategic implication for India
CPEC through PoK	Undermines sovereignty; deepens China’s stake in the disputed region.
Gwadar port	Enables strategic encirclement from the western maritime flank.
String of Pearls	Ring of facilities across the Indian Ocean sea lanes.
Two-front prospect	Forces India to plan for simultaneous pressure on north-western and north-eastern borders.

The Internal Threat Environment

While external threats have remained broadly constant, internal threats have evolved with the country’s political discourse. They test the state’s authority from within and are often deliberately fanned from across the border.

• North-East insurgency: ethnic and secessionist movements, now brought largely under control through concessions and dialogue.
• Punjab militancy: a secessionist movement that required direct military intervention before it was contained.
• Left-Wing Extremism (Naxalism/Maoism): rooted in land-appropriation grievances, it grew into one of the gravest internal security challenges.
• State-sponsored subversion: evidence of Pakistani attempts to foment social unrest, linking internal disorder to external hostility.
• Transnational terror ideologies: the reach of global jihadist movements such as ISIS poses a radicalisation risk that must be pre-empted.

The Changing Character of War

The twenty-first century has redefined conflict. Full-scale wars are increasingly unlikely; in their place come limited, intense and short wars fought simultaneously across multiple domains — land, air, sea, space, cyberspace, the electromagnetic spectrum and the psychological domain.

The Doklam stand-off is a textbook example of psychological warfare, where perception and resolve mattered as much as force.

India’s Strategic Response and Doctrine

▸ Human and Material Capability

India has steadily built both human and material capabilities.

On the human side it fields a superior military and paramilitary force and provides military training to numerous nations — a marker of professional depth.

On the material side, however, dependence on foreign suppliers remains high and indigenous production is comparatively slow, underscoring the need to strengthen the domestic military-industrial complex.

▸ Deterrence Through Denial (the China Strategy)

Against China the core strategy is deterrence through denial — making any aggression prohibitively costly.

This includes deployment of specialised mountain troops along the border, a dedicated mountain strike corps, upgraded border road and airfield infrastructure (for example airstrips capable of handling Su-30 fighters), forward deployment of BrahMos missiles in the North-East, and investment in long-range missiles to project power.

▸ The Maritime Turn and the Blue Economy

As competition in the Himalayas plateaus, the new theatre is the Indian Ocean, where China’s Maritime Silk Road is expanding its naval and economic footprint.

India’s response is to nurture partnerships — with the United States, Mauritius, Seychelles, Japan and others — under the framework of the Blue Economy, to deploy alongside partners such as Vietnam to protect sea lanes of communication (SLOC), and to build towards a blue-water navy. India’s security horizon stretches from the Strait of Malacca to the Strait of Hormuz.

▸ From Deterrence to Direct Action

Historically, restraint against Pakistan meant avoiding pre-emptive or retaliatory strikes and relying on dialogue.

This changed with the cross-border surgical strikes of 29 September 2016, when special forces crossed the Line of Control to destroy terror launch pads — the first such publicly acknowledged action since 1971 — and again with the calibrated air strikes that followed later provocations. The doctrine shifted decisively from passive deterrence towards proactive, visible response.

CASE STUDY — Operation Sindoor (7 May 2025)

Following the Pahalgam terror attack of 22 April 2025, in which 26 civilians were killed by militants linked to The Resistance Front (a proxy of Lashkar-e-Taiba), India launched a precision air-and-missile operation against nine terror-linked sites — four in Pakistan and five in Pakistan-occupied Kashmir.

Executed jointly by the Army, Navy and Air Force, the strikes lasted about 23 minutes, with all weapons launched from within Indian territory.

• Character: described as focused, calibrated and non-escalatory; aimed only at terror infrastructure of JeM and LeT while avoiding military facilities and limiting civilian damage.
• Weapons employed: SCALP cruise missiles, HAMMER precision munitions, loitering (kamikaze) drones, METEOR beyond-visual-range air-to-air missiles and the BrahMos supersonic cruise missile.
• Air defence: a layered shield of S-400 and Akash systems, anti-aircraft guns and electronic-warfare jammers neutralised retaliatory drones and missiles.
• Strategic message: a new red line — if terror is used as state policy, it will be met with a visible and forceful response — marking the shift from deterrence to direct action.

▸ Coercive Diplomacy: The Indus Waters Lever

Security policy now extends to water as strategic leverage. In the wake of the Pahalgam attack the country placed the Indus Waters Treaty of 1960 in abeyance, signalling that terror and normal cooperation cannot coexist.

The move is powerful but carries legal and infrastructural complexities, since the treaty contains no provision for unilateral withdrawal and existing storage on the western rivers remains limited.

▸ The Balance with the United States

At the global level the country has been measured in alliance-building. Continued US engagement with Pakistan has long created doubt about the depth of strategic partnership.

Yet the deepening of defence and technology cooperation reflects an emerging role for India as a strategic hedge against China, even as India avoids being drawn openly into any containment framework that would needlessly antagonise Beijing. India favours strategic autonomy over formal alignment.

▸ Defence Diplomacy and Indigenous Strength

Defence diplomacy — through joint exercises such as Malabar, logistics agreements such as LEMOA, training of foreign personnel and rising indigenous exports (BrahMos to the Philippines, Akash to Armenia) — converts military capability into strategic influence.

The performance of home-built and integrated systems in recent operations has strengthened the country’s standing as a credible defence partner and exporter.

Gaps and Challenges

Challenge	Explanation
No formal doctrine	The absence of a published national security strategy document reflects a lack of political consensus on what actually constitutes internal and external threats.
Incoherent approach	Different, ad-hoc approaches are used against different threats, producing a ‘mixed bag’ rather than a unified strategy.
Import dependence	Heavy reliance on foreign platforms weakens self-reliance and the credibility of indigenous exports.
Porous frontiers	Coastal and border gaps remain infiltration routes for terror proxies.
Institutional silos	Limited synergy among the foreign, defence, research and armed-forces establishments delays decisions.
Resource constraint	Defence spending at roughly 1.9% of GDP limits the pace of modernisation despite a growing absolute budget.

The Way Forward

A future national security strategy must move from a reactive, threat-by-threat posture to a coherent, proactive strategic culture. Its core elements should include:

• Multi-domain territorial defence: securing boundaries at all levels — land, sea and air — against both state and non-state actors.
• Coastal security: closing the gaps that allow infiltration by sea, as demonstrated by past attacks.
• Early boundary resolution: investing political and diplomatic capital to settle pending disputes with Pakistan and China.
• Offensive cyber capability: protecting critical infrastructure and building the ability to deter and respond in the cyber domain.
• Covert and intelligence depth: strengthening capabilities to counter hostile intelligence operations.
• Net security provider: extending a stabilising presence from West Asia to East Asia and preventing destabilisation in the neighbourhood.
• Defence self-reliance: achieving indigenous production capacity and evolving a proactive, institutionalised strategic culture.

Synthesis

India’s security doctrine remains a work in progress — a blend of restraint and resolve, dialogue and deterrence, autonomy and partnership. The trajectory is clear: from a defensive, reactive posture towards a confident, multi-domain and proactive strategy that treats security as the foundation of both sovereignty and development.

The unfinished task is to fuse these strands into a single, coherent national security doctrine.
