Analysis of the recent Chinese nuclear weapon test and it's strategic implications for China's diplomatic and military policies.

Homi Bhabha writes to Prime Minister Nehru about India's international status as a country possessing a plutonium plant but not a nuclear weapons program.

An intelligence report that the fuel core of the Canadian-Indian Reactor (CIR) at Trombay was being changed every six months raised questions about India’s nuclear objectives: a six-month period was quite short for “normal research reactor operations,” but it was the optimum time for using the CIR’s spent fuel for producing weapons grade plutonium. According to INR, India had taken the “first deliberate decision in the series leading to a nuclear weapon,” which was to have “available, on demand, unsafeguarded weapons-grade plutonium or, at the least, the capacity to produce it.”

Pierre Laurent of the French Department of Scientific Affairs describes the first Indian nuclear test and the resulting reevaluation of French nuclear cooperation with India. New guarantees are suggested to ensure that French-supplied nuclear technology and materials could not be used in future Indian nuclear explosions.

British Ambassador Oliver Harvey reports a conversation with the Director of the French Atomic Energy Commission Jules Guéron on the details of Franco-Indian nuclear cooperation.

The Indian Atomic Energy Commission meets with the French High Commissioner for Atomic Energy Joliot-Curie to discuss nuclear cooperation between India and France.

The day of the test, State Department’s Bureau of Intelligence and Research (INR) rushed to update Kissinger. INR provided background on what had happened, how the United States and Canada had inadvertently helped India produce plutonium for the test device, earlier U.S. and Canadian demarches against “peaceful nuclear explosions,” and India’s capabilities to produce and deliver nuclear weapons. The report did not state whether India had made a decision to produce weapons, but it forecast that two large unsafeguarded reactors under construction could eventually “produce enough plutonium for 50-70 nuclear weapons.”

U.S. embassy officials report on an interview with Lauren Gray, the chairman of Canada’s Atomic Energy Control Board (AECB), who had recently visited India. Having spoken with Homi Nusserwanji Sethna, Chairman of the Atomic Energy Commission, and other officials, Gray believed that Sethna opposed a test and that as long as Sethna and Indira Gandhi were in office “there was no chance” that India would test a nuclear device, which would take three to four years to prepare. Other officials with the AECB disagreed with Gray's estimates - based on their assessment of Indian’s ability to produce weapons grade plutonium, they argued that it would take no more than a year to produce a device. They also pointed out that about 18 months earlier there had been a “blackout” of statistical information on plutonium production in India.

At the request of Undersecretary of State John Irwin, the Bureau of Intelligence and Research (INR) prepared an assessment which included a detailed review of Indian’s nuclear facilities and their capacity to produce weapons-grade plutonium as well as capabilities to deliver nuclear weapons to a target. While India had signed agreements with Canada and the United States that nuclear reactors were to be used for peaceful purposes, the Indians were likely to claim that an explosive device for “peaceful” purposes was consistent with the agreements. Whether the Indians were going to test in the near future was in doubt. INR could not “rule out” one in the near future. Further, the “strongest incentive [to test] may well be the desire for the increased status of a nuclear power.” All the same, “it our judgment that a decision to authorize a test is unlikely in the next few months and may well be deferred for several years.” Weighing against a test were the financial and diplomatic costs, for example, “India's full awareness that assistance from the US and other countries (possibly including the USSR) would be jeopardized.”
