ISLAMABAD: Adviser to the National Command Authority retired Lt Gen Khalid Kidwai on Tuesday warned that Pakistan could review its deployment options to restore strategic balance in South Asia, saying India was moving towards a more prepared, potentially first-use capable nuclear posture.

`Pakistan never has and never will accept strategic imbalances to be induced in South Asia,` Mr Kidwai said at the second Islamabad NonProliferation Conference, hosted by the Strategic Vision Institute, an Islamabad based think tank specialising in strategic issues.

`Pakistan will review and re consider all options for appropriate deployments in order to restore the strategic balance and strategic stability while retaining the policy of strategic ambiguity,` he added.

Mr Kidwai and retired Lt Gen Sarfraz Sattar, both former heads of the Strategic Plans Division and advisers to the NCA, said India`s reported deployment of nuclear weapons aboard a submarine, alongside missile modernisation and recent military confrontations, raised the risk of escalation between the two neighbouring arch rivals.

Nuclear warheads Citing the Stockholm International Peace Research Institute`s SIPRI Yearbook 2026 and other publicly available information, they pointed to reports that India had deployed around 12 nuclear warheads on a submarine for deterrence patrols. They also cited missile canisterisation and wider nuclear and conventional modernisation as developments that cast doubt on India`sdeclared No-First-Use policy.

Mr Kidwai said the reported deployment suggested India had mated nuclear warheads with submarine launched ballistic missiles and begun sea based deterrence patrols.

`I do not see any reason as to why an SIPRI report might be inaccurate or speculative,` he said.

`This irresponsible escalatory transition towards creating asymmetry in nuclear posture will have profound destabilising effects on South Asian strategic stability,` he added.

Mr Kidwai said India`s ability to maintain a continuous at sea deterrent further undermined the credibility of its No-FirstUse policy and pointed to a more offensive nuclear posture.

`The operational reality that emerges is that India can undertake a first strike against Pakistan at zero notice,` he said.

Advance notification He also questioned the absence of advance notification for Indian submarine launched ballistic missile tests, warning that such developments could heighten the risk of miscalculation during a crisis.

Referring to the February 2019 confrontation, he said India had reportedly deployed its Arihant nuclear submarine in the Indian Ocean after carrying out air strikes near Balakot in Pakistan, presumably with nuclear weapons aboard. He described the latest reported deployment as part of India`s wider effort to operationalise mated nuclear weapons on submarines.

`Pakistan reserves the right to undertake all appropriate measures to safeguard its national security and preserve strategic balance in the region under all circumstances,` Mr Kidwai said.

He urged India to understand the implications of Pakistan`s Full Spectrum Deterrence policy.

`India in fact will be well advised to read and re-read Pakistan`s policy of Full Spectrum Deterrence and seriously absorb its wide rangingimplications for strategic deterrence, strategic stability, and for India`s security,` he said.

Mr Sattar said the May 2025 conflict between the nucleararmed neighbours showed how quickly conventional hostilities could escalate. The ceasefire came after both sides used cruise and ballistic missiles and India deployed strategic naval assets, he said.

He drew parallels with the 2019 confrontation, when Indian Prime Minister Narendra Modi referred to the deployment of nuclear submarines for deterrence patrols and the positioning of BrahMos missiles along Pakistan`s border.

The May 2025 fighting was more intense, involving kamikaze drones, supersonic BrahMos missiles capable of carrying conventional or nuclear warheads, and cyber and electronic warfare, he said.

`It is now clear that the 2025 conflict was much more lethal in comparison to the 2019 conflict,` Mr Sattar said, warning that the fighting risked spiralling towards nuclear escalation through accident or miscalculation.

He cited India`s canisterisation of land and sea based missiles, pursuit of multiple independently targetable reentry vehicle (MIRV) capabilities, short-range tactical missiles, ballistic missile defences, hypersonic weapons and autonomous platforms as further sourcesofconcern.

Combined with India`s Cold Start doctrine, wider military modernisation and the absence of a bilateral arms control mechanism, these developments raised doubts about its No-First-Use declaration and traditionally recessed deterrence posture, he said.

`Rather, as I said, it signals a shift towards more first use capable posture,` Mr Sattar said.

`The future strategic stability in South Asia is placed on a perilous and worrisome course with heightened risk of misunderstanding and miscalculation, potentially leading to unintended or accidental escalation to the nuclear level,` he added.
