Context: India’s nuclear doctrine has remained broadly unchanged for over two decades, while the strategic environment has changed significantly due to China’s military rise, Pakistan’s evolving nuclear posture, emerging technologies and multipolar geopolitical competition.
- Since its operationalisation in 2003, the doctrine has retained Credible Minimum Deterrence (CMD) and No First Use (NFU) as its core principles.
- The key question is whether the assumptions underlying the early-2000s doctrine remain adequate for the mid-2020s security environment.
Evolution of India’s Nuclear Doctrine
- The 1998 Pokhran-II nuclear tests established India as a nuclear weapons state, while the 1999 Kargil War demonstrated that nuclear weapons do not completely prevent conventional conflict.
- The 1999 Draft Nuclear Doctrine and the Cabinet Committee on Security (CCS) decision of January 4, 2003 provided the basis for India's operational nuclear posture.
- The 2003 framework rests on Credible Minimum Deterrence, NFU, massive retaliation, survivable second-strike capability and civilian control over nuclear weapons.
- The doctrine has provided continuity, predictability and strategic stability for more than two decades, but its underlying strategic assumptions need reassessment.
Changing Strategic Environment
China–Pakistan Strategic Convergence
- China has significantly expanded and modernised its nuclear arsenal, strengthened military infrastructure along the Line of Actual Control (LAC) and deepened defence cooperation with Pakistan.
- Pakistan has diversified its nuclear capabilities, including tactical nuclear weapons, partly intended to offset India's conventional military advantage.
- Unlike the early 2000s, India now faces the possibility of interacting pressures from two increasingly aligned nuclear-armed adversaries during a crisis.
Emerging Military Technologies
- Artificial Intelligence, cyber capabilities, space-based surveillance, hypersonic weapons and ballistic missile defence are transforming the nuclear deterrence environment.
- These technologies can shorten decision-making timelines, threaten command-and-control networks and complicate assumptions about assured retaliation.
- They do not necessarily invalidate India's existing doctrine but require greater alignment between doctrine, capabilities and survivability.
Multipolar Geopolitics
- The Indo-Pacific has emerged as a major arena of great-power competition, with U.S.–China rivalry, closer China–Russia coordination and India's expanding strategic partnerships influencing regional security.
- Nuclear deterrence can therefore no longer be examined only through a bilateral India–Pakistan or India–China framework.
Why a Doctrinal Review May Be Necessary
- Strategic doctrines are policy instruments and can be reviewed when the security environment changes, without necessarily changing their fundamental principles.
- A review could examine command-and-control resilience, second-strike capability, emerging technologies, survivability and the continuing relevance of existing retaliation concepts.
- It could also assess whether India's declaratory posture provides adequate deterrence clarity across different nuclear contingencies.
The Issue of Massive Retaliation
- India's 2003 doctrine envisages massive retaliation following a nuclear attack.
- Pakistan's development of tactical nuclear weapons creates a challenge because their intended role is to complicate India's response options below the level of a large-scale strategic nuclear exchange.
- A doctrinal review could therefore examine whether the existing declaratory policy provides sufficient credibility and clarity across different levels of nuclear escalation.
NFU: Review Without Abandonment
- No First Use (NFU) means India declares that it will not initiate the use of nuclear weapons but will retaliate if subjected to a nuclear attack.
- The existing framework also retains the option of nuclear retaliation following a major biological or chemical attack on India or Indian forces.
- Reviewing NFU need not imply abandoning it; India could reaffirm its rationale, clarify its scope and strengthen the capabilities supporting it.
- Maintaining clarity is important because excessive ambiguity could increase uncertainty, encourage adversaries to alter their calculations and complicate crisis management.
Credible Minimum Deterrence
- Credible Minimum Deterrence (CMD) does not imply maintaining the largest possible nuclear arsenal; it seeks to maintain sufficient and survivable nuclear capability to deter an adversary.
- Its credibility depends not merely on the number of weapons but on survivability, reliable delivery systems, command and control, early warning and assured second-strike capability.
Building Credible Nuclear Capabilities
- Any review should assess the survivability of India's nuclear forces, including command and control, intelligence, early warning, cyber resilience and the nuclear triad.
- India needs to continue modernising delivery systems and ensuring that nuclear forces remain survivable against technological and military threats.
- Nuclear policy should remain aligned with India's broader objectives of strategic autonomy, diplomatic engagement and responsible nuclear stewardship.
WayForward
- Conduct a periodic strategic review of the doctrine without automatically altering its core principles.
- Strengthen second-strike capability and command-and-control resilience to preserve deterrence credibility.
- Account for the implications of AI, cyber, space, hypersonic systems and missile defence for nuclear stability.
- Improve preparedness for crises involving multiple nuclear-armed adversaries and complex escalation pathways.
- Preserve civilian control, strategic restraint and responsible nuclear stewardship while adapting supporting capabilities to changing threats.
