This lengthy report was State Department Bureau of Intelligence and Research's contribution to the first National Intelligence Estimate on the nuclear proliferation, NIE 100-6-57. Written at a time when the United States, the Soviet Union, and the United Kingdom were the only nuclear weapons states, the “Fourth Country” problem referred to the probability that some unspecified country, whether France or China, was likely to be the next nuclear weapons state. Enclosed with letter from Helmut Sonnenfeldt, Division of Research for USSR and Western Europe, to Roger Mateson, 4 June 1957, Secret

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.”

During a discussion with the Canadian embassy counselor, U.S. country desk director David Schneider opined that Indian was unlikely to test a device in the “near future” but he wanted Ottawa’s prognosis. Schneider was also interested in whether the Soviets, with their close relationship with India, might be able to use their influence to “deter” a test. If India tested, the U.S. could respond with a “strong statement,” but whether “punitive” measures would be taken would depend on whether the test “violated existing agreements.” In October 1970, the State Department had cautioned the Indians that a “peaceful nuclear explosion” was indistinguishable from a weapons test and that the test of a nuclear device would be incompatible with U.S.-Indian nuclear assistance agreements.
