Twenty-eight years have passed since Pakistan experienced one of the most consequential moments in its history; Youm-e-Takbeer is not just a date to be commemorated; it is a day embedded in the national consciousness. When the mountains of Chagai bore witness to Pakistan’s nuclear tests, the message conveyed was far greater than the yield of any explosion. It was a declaration that sovereignty, once achieved, requires unwavering defence.
Pakistan’s decision to conduct five nuclear tests on 28 May 1998 was a direct response to India’s detonations earlier that month. It was not a choice taken lightly. With those tests, Pakistan became the seventh nuclear power in the world and the first among Muslim nations. This decision changed the South Asian security architecture and helped restore the balance of power, ensuring that India would not be the sole dominant power in the region.
Youm-e-Takbeer was built on a doctrine of restraint, self-defence, and strategic necessity. It represents strength and resolve, as well as the strategic wisdom of the historically decorated leaders, in addition to our unsung heroes. The political and Army leadership at the time as well as scientists played a key role in building the nuclear capability and going ahead with the tests for the sake of the nation’s sovereignty. Despite immense international pressure and the threat of sanctions, Pakistan undertook the nuclear tests. Following that, the country endured three years of stringent sanctions under the Glenn Amendment, but the renewed sense of security and national pride gave Pakistan the resilience to weather the storm.
Conceptually, the nuclearisation discourse in South Asia is largely shaped by the stability-instability paradox. When two adversaries acquire nuclear weapons, the probability of direct, large-scale escalation decreases while the risk of minor conflicts significantly increases.
Since 1998, both Pakistan and India have been fully aware of the catastrophic consequences that a nuclear war would bring. Despite that, India has repeatedly showcased aggression in the pursuit of a limited war under the nuclear overhang. However, in all limited conflicts between the two adversaries, military actions have been calibrated, signalling deliberate and carefully managed escalation thresholds. The ambiguity surrounding nuclear red lines has kept the conflict well within the spectrum of controlled escalation.
Most recently, the Pakistan-India war of May 2025 served as a real-world answer to the duality regarding whether nuclear weapons bring stability or crisis. After India carried out precision strikes, the situation quickly escalated.
Under the leadership of Air Chief Marshal Zaheer Ahmed Baber Sidhu, the Pakistan Air Force responded decisively in the conventional domain, sending a clear signal that further escalation would come at a cost. India, facing significant aircraft losses, sought external mediation to de-escalate. With tensions rising and the risk of a broader, potentially nuclear confrontation looming, the US stepped in to help ease the situation and prevent it from spiralling further. This way, nuclear deterrence defined the limits of the war, with both sides fighting within its invisible boundary.
For years, Pakistan’s strategic thinkers have said that nuclear weapons are there to stop wars, not fight them. The 2025 conflict seemed to reinforce the idea that, despite how destructive they are, nuclear weapons still act as a powerful deterrent, helping keep the peace in South Asia. Pakistan has repeatedly emphasised that its nuclear arsenal is purely for defence. The objective from the outset has been to ensure that these weapons are never used.
The strategic environment, however, is becoming increasingly complex. Technological advancements have introduced new challenges to deterrence stability. Hypersonic glide vehicles, long-range precision-strike systems, unmanned aerial vehicles, and anti-satellite weapons are no longer theoretical. These capabilities allow adversaries to strike targets without crossing territorial borders. Decision-making timelines have compressed. Ambiguity has increased. The risk of inadvertent escalation has grown.
As the distinction between conventional and nuclear domains continues to blur, the relevance of nuclear deterrence has not diminished. If anything, it has grown. When a country can inflict serious damage without using nuclear weapons, nuclear capability becomes the last line of defence. It sets a clear limit, and even the most aggressive adversary has to think twice before crossing that threshold.
In South Asia, nuclear deterrence continues to function in the background to prevent the crisis from escalating into a full-scale, protracted war. In May 2025, Pakistan delivered a befitting conventional response to India’s aggression under its quid pro quo plus policy. This confidence in its conventional response is rooted in the country’s nuclear deterrence, shaped by the decisive choice of conducting the nuclear tests in 1998, in spite of international pressure and the risk of economic strangulation. The May 2025 war reflects the proven promise of Youm-e-Takbeer. It is not simply the day Pakistan became a nuclear power, but the day it ensured that in a volatile region, peace would have a protector that no adversary could afford to test.
