ABSTRACTIran under Mohammad Reza Pahlavi embarked on one of the most ambitious nuclear programmes of any state in the 1970s. This decision was in part motivated by the zeitgeist surrounding nuclear energy in the 1970s that envisioned the transition from a petroleum- to plutonium-based economy. This decision, however, was soon followed by the Indian ‘Smiling Buddha’ peaceful nuclear explosion. This led the United States and other nuclear suppliers to strengthen restraints on nuclear exports. Many nuclear recipients, particularly in the Third World, objected to US-led changes to the nuclear non-proliferation regime, including the creation of the London Club (later renamed the Nuclear Suppliers Group). To address perceived shortcomings of nuclear suppliers in cooperation on the peaceful uses of nuclear technology, the Iranian nuclear leadership organized the Iran Conference on the Transfer of Nuclear Technology in April 1977. The Persepolis conference, as it came to be known, saw many nuclear suppliers, recipients and industry rally in opposition to US non-proliferation policy under President Jimmy Carter. However, following the Iranian Revolution of 1979, Iran ceased to function as the lynchpin of this opposition to US policy, with the result that the coalition created at the Persepolis conference dissipated.
