FAS - Federation of American Scientists
The Federation of American Scientists was founded in 1945 as a think tank intent on fostering the civilian use of nuclear energy and on protecting humanity of a nuclear war. Regular publications critically describe current nuclear developments and address the issue of nuclear weapons from a global and country-specific perspective. They offer information on nuclear weapons holdings, classified according to strategic and non-strategic nuclear weapons, reserves of nuclear weapons, the stockpile of nuclear weapons and the full inventory of each country. They also provide information on which countries have the technical means to develop nuclear weapons in the near future.
