The U.S. Departments of Defense and State offer instructions about how to respond to the Northern Limit Line Dispute, including measures to restrain South Korea.

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.

Prepared as part of the NSSM 156 policy review, this Special National Intelligence Estimate (SNIE) concluded that the chances of India making a decision to test were “roughly even,” but the post-mortem analysis [see "Why now?," 18 May 1974] argued that based on its own findings, the conclusion ought to have been 60-40 in favor of a decision to test. In its analysis of the pros and cons of testing, the SNIE found that the “strongest factors impelling India to set off a test are: the belief that it would build up [its] international prestige; demonstrate India's importance as an Asian power; overawe its immediate South Asian neighbors; and bring enhanced popularity and public support to the regime which achieved it.” The drafters further noted that a test would be “extremely popular at home, where national pride is riding high” and that supporters of a test believed that it would make the world see India as “one of the world’s principal powers.” The arguments against a test included adverse reactions from foreign governments that provided economic assistance, but the estimate noted that foreign reactions were “becoming less important” to India.

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.”

The State Department asks the U.S. Embassy in India for its assessment of the likelihood that India is planning a nuclear test explosion.

Sonnenfeldt describes for Secretary Kissinger the state of US-French relations after a schism developed in the wake of the 1973 October War, and what impact this would have on the two countries' nuclear cooperation.

Secretary of Defense McNamara and his Deputy Gilpatric discuss whether assisting the French with missile technology would advance their nuclear weapons program. They speculate that it will help indirectly, missile aid would reduce the cost of the French missile research program and those saving could be directed to warhead production.
