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.

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.”

Cable on a discussion with Japanese Disarmament Division Chief Tanaka, who was uncertain whether India would conduct the nuclear test or not.

Report on conversations between Japanese officials and a Pakistani source who indicated the location of the upcoming Indian nuclear test. The cable expressed doubts about the information, suggesting that the "stir" "may have been created largely on personal basis" by the Pakistani source.

In response to a request from the State Department, Ryohei Murata, an official at the Japanese embassy, reported that the Japanese government believed that for prestige reasons and as a “warning” to others, the “Indians have decided to go ahead with a nuclear test” which could occur at “any time.” The Thar Desert in Rajasthan would be the test site.

The Canadian embassy had asked the State Department for information on the intelligence reports from earlier in the year that an Indian nuclear test was “imminent.” The State Department denied the request, but informed the Canadians that the reports were so numerous and their “congruity, apparent reliability, and seeming credibility” so striking that it had become necessary to update official thinking about Indian intentions.

The British Government took the same view as the Canadians, seeing no evidence that the Indians had made a decision to do a nuclear test, although they had the “capability.”

Further discussions with the Canadian embassy counselor disclosed Ottawa’s view that it had no evidence of Indian intentions to test a nuclear weapon or a PNE. The Indians were “leaving their options open.” If they decided to test, however, it would be “impossible” for them to move forward “without revealing some indication of their intentions.”
