Nuclear Proliferation and Accidents

The Clinton Administration and the Indian Nuclear Test That Didn't Happen — 1995-1996 Washington, D.C., February 22, 2013 – In the last months of 1995, U.S intelligence agencies detected signs of nuclear test preparations at India's test site in Pokhran, but the satellite photos that analysts studied were "as clear as mud," according to declassified documents published today by the National Security Archive and the Nuclear Proliferation International History Project.

Washington, D.C., November 19, 2012 – For decades, U.S. command-control-and-communications (C3) systems were deeply vulnerable to nuclear attack, according to a recently declassified Pentagon study. The document, a top secret internal history of the highly complex procedures that connected the White House and senior civilian and military leaders with local commanders awaiting orders to launch bombers and missiles, details sometimes harrowing reports about systemic weaknesses that could have jeopardized U.S. readiness to respond to a nuclear attack.

Washington, D.C., November 6, 2012 – The U.S. intelligence community predicted India's nuclear bomb in 1964 but mistakenly concluded Israel had "not yet decided" to go nuclear, according to newly declassified documents posted today by the National Security Archive and the Nuclear Proliferation International History Project.

Washington, D.C., September 7, 2012 – Eleven years after the terrorist attacks of September 11, 2001, how concerned Americans should be over threats of nuclear terrorism remains a subject of vigorous debate. Declassified documents have confirmed that the U.S. (and other) governments have anticipated the possibility of a terrorist nuclear incident at such high-profile events as the 2009 inauguration of President Barack Obama and the 2010 Vancouver Olympics. Ever since 9/11, U.S. experts have been particularly interested in whether al-Qaeda is trying to acquire a nuclear device.

Washington, DC, September 5, 2012 – The online magazine ForeignPolicy.com today published an extraordinary CIA document on the recent Iraq war which the National Security Archive obtained through a Mandatory Declassification Review (MDR) request to the CIA.

Washington, D.C., July 23, 2012 – The possibility that highly motivated countries, such as Iran in today's environment, could secretly build gas centrifuge plants to produce highly enriched uranium was foreshadowed over fifty years ago by senior officials at the Atomic Energy Commission (AEC) and its contractors. They perceived that countries determined to acquire a nuclear weapons capability could secretly build gas centrifuge facilities to enrich uranium, although it required solving complex technical problems.

Washington, D.C., April 27, 2012 – Tensions between the United States and Pakistan rose through the 1980s over intelligence reports that suggested to U.S. officials that Pakistani leader Zia ul-Haq had repeatedly lied to them about his country's nuclear program, according to recently declassified records published today by the National Security Archive and the Nuclear Proliferation International History Project. Zia's apparent mendacity posed an immediate challenge to U.S.

Washington, D.C., December 5, 2011 – India's "peaceful nuclear explosion" on 18 May 1974 caught the United States by surprise in part because the intelligence community had not been looking for signs that a test was in the works.

Washington, D.C., July 27, 2011 - The United States and Great Britain undertook a secret diplomatic campaign in the late 1970s to prevent a major nuclear proliferation threat – Pakistan's attempted covert purchasing of "gray area" technology for its nuclear weapons program – according to recently declassified "NODIS" (no distribution) State department telegrams published today by the National Security Archive. The Archive obtained the documents through a mandatory declassification review request. The documents do not mention the name A. Q.

Washington, D.C., May 26, 2011 - The U.S. government secretly helped France develop its nuclear weapons and ballistic missile program, and much earlier than previously realized, according to declassified documents compiled and edited by National Security Archive senior analyst William Burr and published jointly with the Nuclear Proliferation International History Project, an Archive partner.
