Rajasthan. His polemics, articulated over five decades, on India's development as a nuclear nation, with civilian and weapons capabilities, have proven both influential and contentious with supporters and detractors alike—of nuclear development and nuclear disarmament. His strong views and trenchant criticism of the inherent inequalities of the global Nuclear Non-Proliferation Treaty and Comprehensive Nuclear Test Ban Treaty regimes are widely known and referenced, as well as being heavily commented on. He often used the term 'nuclear apartheid' to decry this situation and routinely lambasted the five established nuclear states for forcing the Nuclear Non-Proliferation Treaty on everyone else while refusing all proposals for nuclear disarmament, including one proposed by India in 1986. He also coined the phrase 'nuclear ayatollahs' to refer to the western non-proliferation lobby that routinely chided India for pursuing a nuclear programme; and later for finalising an accord on nuclear co-operation with the US in 2007. The so-called 'Subrahmanyam Formula' was widely used, especially in the mid-1960s and throughout the 1970s, to support India's entry into the nuclear club, despite the country's non-violent Gandhian origins and foreign policy roots in Nehruvian pacifism. The formula did not see any contradiction between striving for socio-economic progress and considering large-scale military development for a developing nation like India. Indeed, strategic deterrence, in which a small but effective indigenous nuclear arsenal would play a key part, was seen as vital to balancing things out in an unequal world carved up by Cold War geopolitics. This ingenious and apparently paradoxical stand has been adversely commented upon, being dubbed 'moral exceptionalism' on non-proliferation by several commentators. Significantly, Subrahmanyam also argued that Pakistan too should look to develop a limited nuclear programme of its own – to establish its own deterrent against conflict. This was met with great suspicion in Pakistani circles, and seen variously as an insult or a challenge. He also concluded in the 90's that India needed only 150-odd warheads to achieve minimum deterrence. And that this had been achieved by 1990, a point noted by many as a good reference to India's nuclear stockpile. In 1979, as Chairman of India's Joint Intelligence Committee, Subrahmanyam authored a Cabinet note arguing for the resumption of India's nuclear weapons programme. The programme had been shut down in 1977 by Prime Minister Morarji Desai on his assuming office, largely on account of seeking to return to India's pacifist foreign policy roots. Subrahmanyam's note was
