Fresh warnings from New Delhi and Islamabad have revived a troubling question: did last year’s four-day military confrontation strengthen deterrence, or convince both countries that another limited war could be managed?

By Muhammad Munaeem Jamal | 19 October 2026

On 15 October, Indian Defence Minister Rajnath Singh delivered a warning that Pakistan could hardly ignore. Speaking at a defence conclave in New Delhi, Singh said another terrorist attack originating from Pakistan would invite an Indian response stronger than the one delivered during Operation Sindoor in May 2025. He presented that operation, along with India’s earlier strikes in 2016 and 2019, as evidence of a change in New Delhi’s approach to terrorism.

Pakistan responded the following day. At a Foreign Office briefing on 16 October, Islamabad condemned Singh’s remarks as a threat of military aggression. Its spokesperson referred to the May 2025 fighting and said Pakistan remained prepared to defend its sovereignty.

On 17 October, General Aamer Raza, Pakistan’s Commander National Strategic Command, added another warning. Addressing military cadets at Kakul, he said miscalculation by an adversary could invite a response beyond what the initiator anticipated.

The statements were not identical. India’s warning was framed around another terrorist attack. Pakistan’s response emphasised sovereignty and the consequences of military aggression. But together they revealed how little strategic reassurance had emerged from the ceasefire of 10 May 2025.

That confrontation ended after four days of fighting involving aircraft, missiles and drones. Both governments subsequently portrayed their military performance as successful. The firing stopped. The competing interpretations of what had happened did not.

This matters because another India–Pakistan crisis is unlikely to begin with a formal declaration of war. A major terrorist attack, an intelligence assessment or a military strike described as limited could set events in motion. The danger is that each government may now believe it understands how far it can go before the other side decides to stop.

The lesson India believes it learned

India’s response to terrorism has changed over the past decade. After the 2008 Mumbai attacks, which India attributed to Pakistan-based Lashkar-e-Taiba militants, New Delhi pursued diplomatic pressure rather than launching a comparable military campaign across the international border.

In September 2016, following an attack on an Indian Army installation at Uri, India announced cross-Line of Control strikes against militant positions.

The next major change came in February 2019. After a suicide bombing killed Indian security personnel at Pulwama, Indian aircraft attacked Balakot in Pakistan. Islamabad responded with an air operation, during which an Indian aircraft was shot down and its pilot captured. Pakistan later returned him. The crisis ended without a wider war.

India’s political leadership interpreted these operations as evidence that military retaliation was possible despite the nuclear danger. As I examined during the 2025 confrontation, that evolving doctrine depends on the belief that retaliation can remain bounded.

Operation Sindoor in May 2025 extended that approach. Following the 22 April terrorist attack at Pahalgam, which killed 26 people, India struck locations in Pakistan and Pakistan-administered Kashmir that it identified as militant infrastructure. Pakistan rejected allegations of state involvement in the Pahalgam attack and disputed India’s description of some targets.

The confrontation subsequently expanded beyond the initial strikes. According to Christopher Clary’s independent assessment for the Stimson Center, the fighting involved unprecedented uses of cruise missiles, conventionally armed ballistic missiles and attack drones in the India–Pakistan rivalry. Indian forces demonstrated the ability to strike targets across considerable distances inside Pakistan.

New Delhi may therefore believe it has established a more credible military response to future terrorist attacks. Yet a government can decide how to begin a military operation. It cannot independently decide how its adversary will interpret or answer it.

What Pakistan believes it demonstrated

Pakistan’s strategic problem is different. India possesses a substantially larger economy and conventional military establishment. Pakistan has long relied on the ability to impose unacceptable costs on an adversary to deter military attacks. That approach includes conventional forces and nuclear weapons.

But the confrontations of 2019 and 2025 showed that nuclear deterrence does not prevent all conventional military operations. India was prepared to strike. Pakistan responded.

During the opening phase of the May 2025 fighting, Pakistani forces likely brought down several Indian aircraft, according to the Stimson Center’s assessment. That was a meaningful military result, although the exact number and circumstances of the losses have remained contested. My earlier fact-check examined the difference between aircraft-loss claims and independently established evidence.

Pakistan’s leaders could view the episode as evidence that India cannot conduct military operations without paying a price. Their challenge is determining what follows from that conclusion.

If India strikes again, Pakistani decision-makers may feel compelled to respond forcefully to preserve the credibility of their deterrent. India, meanwhile, may interpret Pakistan’s response as an escalation requiring another round of retaliation.

The governments would then be acting according to different versions of the same logic: a failure to respond now could encourage the other side to take greater risks later. Deterrence can fail even when both governments believe they are defending it.

The October warnings reveal the problem

Singh’s 15 October remarks did not announce a new Indian military operation. They described the consequences India says would follow another terrorist attack originating from Pakistan. A conditional threat is not evidence that troops have been ordered into action.

Pakistan’s Foreign Office nevertheless treated the remarks as dangerous. Its 16 October response rejected India’s language and recalled Pakistan’s military performance during the previous confrontation. General Raza’s warning the following day placed particular emphasis on the consequences of miscalculation in a nuclearised environment.

The sequence illustrates how quickly statements aimed at domestic or military audiences can become part of a confrontation between governments. An Indian minister may intend to reassure Indian voters that another attack will not go unanswered. A Pakistani official may intend to reassure the Pakistani public that the country’s military is prepared. Each statement also reaches the other country’s political and military leadership.

A warning meant to discourage action can be interpreted as preparation for action. Its significance depends on whether it is accompanied by changes in military deployments, operational readiness or diplomatic communication. The October statements warrant scrutiny. On their own, they do not establish that war is imminent.

Who won the four-day confrontation?

The answer depends heavily on which official account one accepts. India emphasised the precision and reach of its attacks, particularly the ability to strike military facilities and targets well beyond the Line of Control. Pakistan highlighted its air combat performance and the losses it said it had inflicted on Indian aircraft.

Both governments made claims that independent observers could not fully verify. Clary’s Stimson Center assessment offers a more cautious account. It concluded that India demonstrated significant long-range strike capability and exposed vulnerabilities in Pakistan’s air defences. The study also assessed that Pakistan likely inflicted meaningful aircraft losses during the initial phase of the fighting.

It found far less independently observable damage from some subsequent Pakistani attacks than official accounts suggested. The result was not an uncomplicated victory for either side.

India showed it could reach targets inside Pakistan. Pakistan demonstrated that such operations could carry military costs. Both governments retained the capacity to continue fighting when the ceasefire was reached.

The most consequential outcome may therefore have been political rather than military. Each side emerged with evidence supporting its preferred account of deterrence. That creates an incentive to repeat the experiment.

Why the next crisis may be harder to control

Military organisations learn from combat. After May 2025, Indian and Pakistani commanders had reason to examine their air defence performance, electronic warfare systems, missile operations and use of drones. They could identify equipment that performed well and tactics that required revision.

Future operations may consequently be more sophisticated. But greater military precision does not necessarily make escalation easier to control.

Suppose one country attacks a facility it believes supports hostile operations. The other government may view that facility as part of its broader national defence infrastructure. The attacking government may believe it has selected a limited target. The defending government may interpret the strike as preparation for a larger attack.

An operation can hit precisely the intended target and still produce consequences its planners did not anticipate. The expanding range of weapons available to both countries makes the issue more serious. During previous crises, geography placed practical limits on certain operations. The May 2025 fighting demonstrated that those limits have weakened. Targets once considered relatively insulated from conventional attack may no longer appear so secure.

Nuclear weapons do not make war inevitable

India and Pakistan have lived with nuclear deterrence for decades. Their leaders understand that uncontrolled escalation could have catastrophic consequences. Yet nuclear weapons do not prevent every conventional clash.

The Kargil conflict in 1999, the Balakot confrontation in 2019 and the fighting of May 2025 all occurred after both countries had demonstrated nuclear capabilities. The presence of nuclear weapons may discourage an all-out war while leaving room for smaller military operations. This is sometimes described as the stability–instability paradox.

The concept is useful, but it should not be treated as a mechanical explanation for every India–Pakistan confrontation. Political decisions, intelligence failures and domestic pressures also shape events.

The May 2025 crisis did not demonstrate that nuclear war was imminent. Independent analysis found relatively limited overt nuclear signalling compared with some earlier crises. That observation matters because sensational descriptions of a near-nuclear catastrophe can obscure what actually happened.

The danger was serious enough without exaggeration. Military strikes were exchanged between two nuclear-armed states, and neither government could guarantee how far the fighting might spread. Nuclear weapons raise the consequences of an otherwise conventional miscalculation.

Diplomacy has become too thin

A functioning diplomatic relationship cannot eliminate the disputes between India and Pakistan. It can provide opportunities to communicate intentions before a crisis reaches the military stage. Those opportunities have diminished.

Relations deteriorated sharply after India changed the constitutional status of Jammu and Kashmir in August 2019. Pakistan downgraded diplomatic ties and suspended much bilateral trade. The May 2025 fighting further deepened mistrust.

Military communication channels remain important, particularly during ceasefire negotiations. But they cannot substitute for political engagement. A military officer can communicate an instruction to stop firing. Resolving the political dispute that produced the fighting requires decisions by governments.

The absence of regular dialogue creates another problem. Public statements become disproportionately important. When leaders rarely communicate privately, the other side may rely on speeches and press briefings to interpret intentions. Those statements are often designed for domestic audiences rather than diplomatic precision.

India and Pakistan do not need to agree on Kashmir to recognise the practical value of reliable communication.

The United States may not always provide an exit

The United States played an important diplomatic role during the final stages of the May 2025 confrontation. President Donald Trump publicly announced a ceasefire on 10 May, while American officials engaged with both governments.

India and Pakistan offered different accounts of how the agreement was reached. New Delhi emphasised direct communication between the two militaries and rejected the characterisation of the outcome as externally mediated. Islamabad acknowledged the importance of American diplomatic involvement.

Independent analysts identified international diplomacy as relevant to the crisis’s conclusion. Yet the precise contribution of outside governments remains disputed. My contemporaneous account of the May 2025 ceasefire discussed the fragility of that halt in fighting.

Washington’s relationship with India is shaped partly by its strategic competition with China. Its relationship with Pakistan involves different security and regional interests. American officials may again seek to prevent escalation, but their influence will depend on the circumstances.

Neither New Delhi nor Islamabad should build its crisis-management strategy around the assumption that another government will intervene successfully before the situation deteriorates.

The economic stakes are unequal, but real

India’s much larger economy gives it greater capacity to absorb the costs of a short confrontation. That does not make military escalation economically harmless. Security crises can affect investment decisions, aviation, trade and financial-market confidence.

For Pakistan, the economic consequences could be more severe. The country remains dependent on external financing and an IMF-supported reform programme. A prolonged confrontation could increase government expenditure while making investors more cautious. It could also complicate efforts to strengthen exports and maintain stable foreign exchange inflows.

Pakistan’s economic vulnerability does not determine its military response. Governments sometimes accept substantial economic costs when they believe national security is at stake. But the costs deserve greater attention in public debate.

The May 2025 confrontation lasted four days. There is no reason to assume that another confrontation would end within the same period. A longer conflict could impose pressures that neither government’s victory narrative adequately acknowledges.

Kashmir and the unresolved triggers

The immediate trigger for the May 2025 confrontation was the Pahalgam terrorist attack. The deeper political dispute remains Kashmir.

India considers Jammu and Kashmir an integral part of the country and attributes major attacks in the region to Pakistan-linked militant networks. Pakistan disputes India’s position on Kashmir and rejects accusations that its state directed the Pahalgam attack.

These disagreements are not resolved by demonstrating military capability. Another issue has added to the strain. India placed the Indus Waters Treaty in abeyance following the April 2025 attack. Pakistan has opposed that decision and warned of consequences for its water rights.

The treaty has long provided a framework for managing water-sharing disputes despite hostile political relations. Its uncertain future introduces another source of tension into an already difficult relationship.

A border incident, terrorist attack or dispute over water can acquire greater political significance when relations are already strained.

Has the risk of another war increased?

There is no credible basis for assigning a precise probability to another India–Pakistan war from the October statements alone. The ceasefire established in May 2025 has held, even as the political relationship remains deeply troubled.

The latest exchange of warnings does not demonstrate that either government has chosen to resume fighting. Nevertheless, the strategic environment has changed.

India has become more explicit about its willingness to conduct cross-border strikes after major terrorist attacks. Pakistan has made clear that it intends to answer such strikes militarily. Both governments have recent combat experience that may influence their confidence in future operations.

That combination creates a persistent risk of miscalculation. The most useful warning indicators would be concrete military preparations, major changes in deployment patterns, or a serious breakdown in the communication channels that helped stop the previous fighting.

Political speeches matter, but they should not be confused with operational decisions. The greatest danger is not necessarily a deliberate decision to launch a prolonged war. It is a sequence of decisions in which each government believes it is conducting a limited operation and responding proportionately, while the confrontation grows beyond the original plan.

The lesson of May 2025

India and Pakistan ended their four-day confrontation without a general war. That was an important outcome. It should not be mistaken for proof that future fighting can be controlled with equal success.

The military experience of May 2025 may have strengthened confidence on both sides. India demonstrated that it could strike targets across Pakistan. Pakistan demonstrated that Indian military action could carry significant costs. Those conclusions can coexist. They can also encourage both governments to believe that another confrontation would reinforce their deterrence.

The October warnings show that neither side has abandoned this language. Yet military credibility is not the only requirement for national security. Reliable communication matters, particularly when an adversary may interpret an attack differently from the government that ordered it.

The ceasefire of 10 May 2025 proved that India and Pakistan could stop fighting. The unanswered question is whether they learned enough from that confrontation to prevent the next one.
