April 23, 1964

Letter from Thomas Hughes, Director, Office of Intelligence and Research, Department of State, to Director of Central Intelligence John McCone

This document was made possible with support from Carnegie Corporation of New York (CCNY)

Noting new intelligence information on the Indian and Israeli nuclear programs, as well as the possibility of developments concerning Sweden, Hughes requested McCone to initiate a new estimate of nuclear proliferation trends, which would eventually become part of a October 1964 National Intelligence Estimate (NIE). Hughes enclosed draft “terms of reference,” that included questions about the possibility of “clandestine” weapons programs and new technological developments that could make weapons development “easier” (perhaps a reference to gas centrifuge technology that the 1964 NIE would discuss).
