A meeting between British Foreign Office and State Department officials on the Indian nuclear problem occurred the same month that Indian Prime Minister Gandhi approved the “final preparations for a PNE.” Deputy Assistant Secretary of State Christopher T. Van Hollen (the father of the future Maryland Congressman) and his colleagues followed the approach taken by the Special National Intelligence Estimate, which was close to that taken by the British Joint Intelligence Committee. According to country director David Schneider, the “odds were about even” that India would make a decision, but once it was made, India could test very quickly. There was “no firm intelligence” that a “go-ahead signal” to prepare for a test had been made. Schneider reviewed bilateral and multilateral steps, proposed in the NSSM 156 study, that the U.S. and others could take to try to discourage an Indian test and the range of reactions that would be available if India went ahead. A “weak” U.S. reaction, Schneider observed, would suggest that Washington would “acquiesce” if other countries followed India’s example.

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.
