State Department cable 104613 to Consulate, Jerusalem, 'India Nuclear Explosion'

The day of the test, State Department’s Bureau of Intelligence and Research (INR) rushed to update Kissinger. INR provided background on what had happened, how the United States and Canada had inadvertently helped India produce plutonium for the test device, earlier U.S. and Canadian demarches against “peaceful nuclear explosions,” and India’s capabilities to produce and deliver nuclear weapons. The report did not state whether India had made a decision to produce weapons, but it forecast that two large unsafeguarded reactors under construction could eventually “produce enough plutonium for 50-70 nuclear weapons.”
