Washington, DC, June 5, 2014 – During the North Korean nuclear crisis of the 1990s, the United States and South Korea shared blunt concerns about the possible outbreak of military hostilities with Pyongyang, according to newly published internal documentation from the National Security Archive. In April 1994, South Korean Defense Minister Rhee Byong Tae told U.S.
Washington, D.C., April 21, 2014– Henry Kissinger played a slightly reluctant but nonetheless highly influential role in establishing the Nuclear Suppliers Group (NSG) in the mid-1970s, motivated equally by concern about nuclear proliferation and a desire to keep U.S. officials from "charging around the world, like Don Quixote," according to documents posted today by the National Security Archive and the Nuclear Proliferation International History Project.
Washington, D.C., February 28, 2014 – Sixty years ago, on 1 March 1954 (28 February on this side of the International Dateline), on Bikini Atoll in the Marshall Islands, the U.S. government staged the largest nuclear test in American history. The BRAVO shot in the Castle thermonuclear test series had an explosive yield of 15 megatons, 1000 times that of the weapon that destroyed Hiroshima and nearly three times the 6 megatons that its planners expected.
Washington, D.C., December 16, 2013 – The Soviet Union assisted the United States in its effort to curb South Africa's nuclear program in August 1977 when Soviet General Secretary Leonid Brezhnev sent President Jimmy Carter a message that Moscow's spy satellites had noticed signs of nuclear weapons test preparations at a site in the Kalahari Desert. Very quickly the U.S. National Reconnaissance Office (NRO) directed spy satellites to photograph the site which intelligence analysts later agreed was geared to nuclear testing. The U.S.
Washington, DC, November 22, 2013 – The final shipment of highly enriched uranium from former Soviet nuclear warheads to the U.S. on November 14, and President Obama's award of the Presidential Medal of Freedom to former Senator Richard Lugar on November 20, have brought new public attention to the underappreciated success story of the Nunn-Lugar initiative — the subject of a new research project by the National Security Archive, which organized the first "critical oral history" gathering this fall of U.S. and Russian veterans of Nunn-Lugar.
Washington, D.C., November 22, 2013 – The arrest of a Pakistani national, Arshed Pervez in July 1987 on charges of illegal nuclear procurement roiled U.S.-Pakistan relations and sharpened divisions within the Reagan administration, according to recently declassified documents published today by the National Security Archive and the Nuclear Proliferation International History Project.
Washington, D.C., October 7, 2013 – A nuclear accident never produced a nuclear detonation, but according to a new book by Eric Schlosser every nuclear-tipped missile "is an accident waiting to happen, a potential act of mass murder." Schlosser's book, Command and Control: Nuclear Weapons, the Damascus Incident, and the Illusion of Safety (Penguin Press, 2013) includes a truly sobering account of safety breakdowns and failures from the 1950s to the 1980s.
Washington, D.C., August 2, 2013 – The United States and Soviet Union conducted underground testing that sometimes produced significant "venting" of radioactive gases and particles which crossed international borders, even after signing the Limited Test Ban Treaty fifty years ago, in August 1963. That posed potential health hazards, but also created problems for U.S.-Soviet relations, according to documents recently uncovered through archival research. To minimize the problem, both superpowers tacitly agreed to keep their disagreements secret.

Washington, D.C., April 23, 2013 – China was exporting nuclear materials to Third World countries without safeguards beginning in the early 1980s, and may have given Pakistan weapons design information in the early years of its clandestine program, according to recently declassified CIA records. The formerly Top Secret reports, published today by the National Security Archive and the Nuclear Proliferation International History Project, are the CIA's first-ever declassifications of allegations that Beijing supported Islamabad's nuclear ambitions.
