Strategic Restraint in South Asia: A Paradigm Shift
During the Cold War, strategic restraint was understood as managed stability between superpowers. In South Asia, this assumption does not hold. Within this region, the war of narratives sometimes has the same detrimental effects as the use of kinetic force. In this regard, restraint by one can be perceived as passivity by the other. This perception can prompt actions that undermine strategic stability. Over the years, India has sought the possibility of fighting a limited conventional war below Pakistan’s nuclear thresholds with the aim of establishing a ‘New Normal’.
The May 2025 War and the 'New Abnormal'
However, the May 2025 war and the exceptional response of the Pakistan Air Force under the visionary leadership of Air Chief Marshal Zaheer Ahmed Baber Sidhu led to a ‘New Abnormal,’ which India did not anticipate. It showed that deterrence is not just posture but a strategic performance, and one nuclear power cannot force another to bend to its will. Resultantly, the new deterrence grammar in South Asia has introduced ‘signalling warfare’ through calibrated actions and strikes aimed at communicating resolve and capability.
Historical Patterns of Conflict
Since nuclearisation, major Pakistan-India wars, including Kargil in 1999, the 2001-02 military stand-off, post-2008 Mumbai tensions, the 2016 Pathankot and Uri attacks, and the February 2019 crisis, have consistently followed a predictable pattern. Indian political leaders externalise attribution by assigning responsibility to Pakistan under allegations of terrorism instead of admitting their own security failure. Pakistan has, in all instances, relied on diplomatic means and has used calibrated military action only when required to resolve tensions.
Operation Sindoor and PAF's Decisive Role
However, over the years, Indian brinkmanship has increased exponentially. Guised as strategic boldness, it has led to the belief that India enjoys escalation dominance. In this light, following the Pahalgam terrorist attack, India launched Operation Sindoor without due diligence or just cause. The frenzied conduct of the IAF exceeded the scale of prior hostilities. It conducted airstrikes and launched tactical missiles inside mainland Pakistan. The PAF played a decisive role in thwarting Indian overconfidence by successfully downing several Indian jets, intercepting multiple hostile UAVs, and neutralising advanced Indian installations in a calibrated military action. This phenomenal response was complemented by the Army Air Defence Command, especially for neutralising enemy projectiles headed towards Pakistan.
Pakistan's 'Quid Pro Quo Plus' Strategy
Imposing policies of massive retaliation as nuclear blackmail against India, Pakistan had aspired to create space for limited conflict and surgical strikes. This time, the world saw a spectacle of Pakistan’s doctrinal and operational maturity. PAF’s exceptional performance demonstrated its credible deterrence and exposed the limits of India’s so-called ‘New Normal,’ aimed at normalising a limited conventional war under the nuclear overhang. Pakistan, under its policy of ‘Quid Pro Quo Plus’, executed a more assured conventional response, quashing New Delhi’s pursuit of escalation dominance. It also became clear that Pakistani decision-makers, unlike the Indian political circle, simply do not obsess over the role of nuclear weapons in crisis environments.
Restraint by Design: A Strategic Calculation
Pakistan possessed an “adequate suite” of sophisticated niche technologies capable of targeting Indian military assets, thereby eroding India’s strategic ambitions. Similarly, under the dynamic and professional leadership of ACM Baber Sidhu, the PAF had multiple opportunities to down even more Indian aircraft, yet deliberately exercised restraint. This military manoeuvring earned Pakistan both global and regional recognition as a more stabilising actor. Hence, Pakistan’s ‘restraint by design’ is a classic example of disciplined and proportionate strategic calculation.
Operation Marka-e-Haq: Multi-Domain Readiness
Moreover, Operation Marka-e-Haq marked a first in which warfare signalling was grounded in multi-domain readiness. Under the logic of the Full-Spectrum Deterrence doctrine, Pakistan’s integrated response combined conventional retaliatory strikes with coordinated actions across multiple domains. India’s ambitions to unilaterally dictate the rules of engagement were constrained, without the need to resort to any nuclear signalling. Hence, Pakistan’s deterrence rationale was centred on both deterrence by punishment and deterrence by denial in the conventional space. The battlespace became the operational stage for Pakistan’s cross-domain deterrence in action.
Layered Resilience and Diplomatic Outreach
The country’s layered resilience, the rapid imposition of costs, and diplomatic outreach credibly managed the situation at the conventional level. Despite the Indian attempts to strike at Pakistan’s airbases, the adversary was clearly conveyed that Pakistan’s command-and-control architecture is designed with survivability in mind, technically, institutionally, and doctrinally. Thus, the evolving grammar of deterrence in South Asia leaves no space for any ‘New Normal’, with Pakistan demonstrating a clear conventional response strategy characterised by strategic prudence and operational clarity.
Future Deterrence and Responsible Nuclear Conduct
Under the new grammar of deterrence and as a responsible nuclear power, Pakistan exercised a deliberately restrained yet resolute response to Indian provocations. The ingenuity and remarkable performance of the PAF grounded deterrence in measured capability rather than performative risk, redefining how nuclear thresholds are managed. However, in the future, the idea of a limited nuclear war remains inherently dangerous, particularly in the context of India’s ambitions for escalation dominance. Therefore, sustaining deterrence is a prerequisite in the South Asian nuclear domain anchored in credible signalling vis-à-vis clear communication, mutual restraint, and robust crisis management mechanisms.
