India can look back with more than a fair measure of satisfaction on the past two decades since its nuclear weapon tests of May 1998. Those tests signalled a strategic shift. This article therefore looks at the international situation and tendencies that prevailed in the run up to these tests. It then presents an assessment of the international reaction as a consequence of that bold and courageous action; as well as of the comprehensive endeavour to address the challenges and maximise the opportunities presented.

The 1998 nuclear tests conducted by India heralded yet another nuclear age. The instant response of a section of the international community was highly pessimistic. It foresaw regional instability, collapse of the global nuclear order and serious crisis in the global nuclear non-proliferation regime. As a result, overlooking India’s security imperatives, a number of countries reacted with hostility against the Indian nuclear tests. Even international organisations were mobilised against India.

Post-Pokhran II the global nuclear environment has changed both in terms of developing niche technologies as also the nuclear strategies. Apart from the traditional challenges, there are new threats emerging in the form of cyber, space, hypersonic glide vehicles, nuclear terrorism, etc. The development of multiple nuclear dyads and triads further makes the security environment increasingly complex, as nations now have to deal with multiple nuclear problems and adversaries.

May 11, 2018, marks the twentieth anniversary of the Shakti-series of tests. In 1998, India conducted five nuclear tests on May 11 and 13. The government stated that in the five tests, advanced weapon designs had been tested. On May 11, declared as the National Technology Day, the three tested devices were of 45-kilotons thermonuclear, 15-kilotons fission and 0.2 sub-kiloton yields. On May 13, India continued the testing of nuclear devices. Both the tests were of the sub-kiloton yields—0.5 and 0.3. These tests heralded India as a nuclear weapon state.

Was the 1998 Pokhran test a historical watershed as many contemporary observers believed? This article looks at its impact on the nuclear non-proliferation regime, regional security, India’s position in global institutions, and the ongoing global power shift: the non-proliferation regime continued along the old dispute lines; regional conflict behaviour did not change at all; India grew into global institutions not because of nuclear tests but because of her remarkable economic development; the re-arrangement of global power follows more basic trends as well.

India’s ‘dual use’ nuclear policy has been strung out from the beginning between the peaceful atom and military atom as illustrated in Jawaharlal Nehru’s use of the phrase for the country’s nuclear energy programme—‘Janus-faced’. However, the Indian Government has been too influenced by its own rhetoric of peaceful use to equally emphasise the security aspects that the phrase implied.
