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.”

This CIA report on India, “India’s Nuclear Procurement Strategy: Implications for the United States,” has comparatively few excisions. It discusses in some detail Indian efforts to support its nuclear power and nuclear weapons development program by circumventing international controls through purchases of sensitive technology on “gray markets.” The report depicts a “growing crisis in the Indian civil nuclear program,” which combined with meeting nuclear weapons development goals, was forcing India to expand imports of nuclear-related supplies. The purchasing activities posed a “direct challenge to longstanding US efforts to work with other supplier nations … for tighter export controls.”

This massively excised report indicates the Agency’s strong views about releasing its knowledge of India’s nuclear weapons activities, even when the information is decades old. That many of the pages are classified “Top Secret Umbra” suggests that some of the information draws on communications intelligence intercepts, another highly sensitive matter.

As this report indicates, the recommendations made in the 1974 post-mortem of the Indian nuclear test failure had little impact. The authors identified a basic disconnect between “national level users”—-the top policymakers-—and those who “set analytical and collection priorities in the intelligence community.” The latter were not sure how high a priority that the policymakers had given to nuclear proliferation intelligence. Moreover, a study for the Defense Department produced by MIT chemistry professor (and future DCI) John Deutch questioned whether the intelligence community “is adequately focused and tasked on proliferation matters.” This would be a recurring problem for the CIA and other intelligence agencies.

Having written off an early test, the day that it took place the Embassy scrambled to come up with an explanation. Deputy Chief of Mission David Schneider signed off on the telegram because Moynihan was in London. While the Embassy had no insight on the decision-making, it saw domestic politics and “psychological” explanations for the test: the need to offset domestic “gloom” and the need for India to “be taken seriously.” According to the telegram, “the decision will appeal to nationalist feeling and will be widely welcomed by the Indian populace.”

A follow up to John J. Pinajian's 4 April 1973 report on "India's Nuclear Position." Pinajian got some access to the Bhabha Atomic Research Center, but noticed the absence of personnel responsible for experimental work. Moreover, he was getting cooperation from the Institute for Fundamental Research to conduct an experiment.

The possibility that India had made a decision to test surfaced in a message from the U.S. consulate in Bombay (Mumbai) signed off by Consul David M. Bane. The latter reported that Oak Ridge Laboratory scientist John J. Pinajian, then serving as the Atomic Energy Commission’s scientific representative in India, had pointed out several “indications”—-notably his lack of access to key individuals and facilities in India’s atomic establishment--suggesting that India “may well have decided” to test a nuclear device. While stating that Pinajian’s evaluation was “subjective and impressionistic,” Consul Bane agreed that the atomic energy establishment did not want this American poking around because he might find out too much. Bane further observed that a nuclear test “in the not too distant future” could meet India’s political goals and help attain “greater recognition major power status.”

The interagency group prepared a response to NSSM 156 on 1 September 1972 and it was sent to Kissinger. The summary of the study reproduced here includes the conclusion that an Indian test would be “a set-back to nonproliferation efforts” and that Washington should “do what [it] can to avert or delay” one. Thus, recommendations included a number of unilateral and multilateral actions that the United States government could take, noting that “given the poor state” of Indo-American relations, an “overly visible” U.S. effort would more likely speed up an Indian decision to test a device, Even non-US efforts were likely not to “be per se effective.”

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.

The Embassy acknowledged that India had the “technical know-how and possibly materials to develop [a] simple nuclear device within period of months after GOI decision to do so.” Nevertheless, it saw no evidence that a decision had been made to test a device. Moreover, capabilities to deliver nuclear weapons were limited, with no plans in sight to “develop [a] missile launch system.”
