Division of Research for USSR and Eastern Europe, Department of State. Subject The topic of the resource Armament Atomic Energy Brazil Description An account of the resource This recently declassified, lengthy report was INR's contribution to the first National Intelligence Estimate on the nuclear proliferation, NIE 100-6-57, which the bureau itself had requested in late April 1957. 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. Among the Latin American countries, Brazil was the only one which could produce nuclear weapons within 10 years but only "with substantial and continuing outside assistance." Nevertheless, Brazil had "evidenced no desire to develop an atomic war potential," and that was unlikely to change in the near future.
