If peace has held in South Asia for nearly two decades, despite some serious provocations, it is essentially because of the 'minimum nuclear deterrence' that Pakistan acquired on May 28, twenty years ago. On that day, Pakistan detonated seven nuclear explosions at Chaghi, Balochistan, which had become inevitable after India conducted a string of explosions earlier that month. On May 28 ever since Pakistan became the seventh member of the elite class of nuclear weapon states, the Pakistani nation therefore proudly celebrates Youm-e-Takbeer. It was India's atomic tests in 1974 which put Pakistan on the path to nuclear-weapon capability and now it was India again that compelled Pakistan to go for these tit-for-tat explosions. Licking wounds suffered at the hands of Chinese in border skirmishes in 1961 and browbeaten by China's atomic tests three years later Indian leadership decided to develop nuclear weapon capability. Indian leadership was now making up its mind to go nuclear; it refused to sign the Non-Proliferation Treaty (NPT), denied access to its nuclear facilities for international inspections, crystallising an "elite consensus" to carry out atomic explosions, although New Delhi continued to harbour 'ambivalent' feelings about nuclear weapons. During these years Pakistan was, one must say quite credulously, vouchsafing for embracing the NPT and turning the region into a nuclear-weapon-free zone. But the 1974 explosions shook Pakistan out of its sweet dreams, and it was then Prime Minister Zulfiqar Ali Bhutto who called scientists for a meeting at Multan and decided to acquire a matching capability. Since India had adopted the plutonium route by stealing fissile material from the reactor gifted by Canada, and Pakistan being beneficiary of Canadian assistance and had suffered, vicariously, denial of fuel it was decided that Pakistan would go for the uranium route. Dr Abdul Qadeer was called in to set up a uranium enrichment plant, and the country was on the way to become a nuclear weapon state. But even when it had acquired the desired potential to go nuclear the explosions were never on the cards, until India carried out its explosions in 1998.
