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.
Washington, D.C., December 21, 2010 - The Wikileaks database of purloined State Department cable traffic includes revelations, published in the Washington Post and the New York Times about tensions in U.S.-Pakistan relations on key nuclear issues, including the security of Pakistan's nuclear arsenal and the disposition of a stockpile of weapons-grade highly-enriched uranium. (Note 1) These frictions are not surprising because the Pakistani nuclear weapons program has been a source of anxiety for U.S. policymakers, since the late 1970s, when they discovered that Pakistani metallurgist A.Q.
Washington, D.C., August 11, 2010 - The next nuclear policy challenge for the Obama administration, right after Senate action on the New START Treaty, will be Senate ratification of the Comprehensive Test Ban Treaty (CTBT), which President Obama sees as a condition for a world free of nuclear weapons. As he declared in his Hradcany Square speech, "After more than five decades of talks, it is time for the testing of nuclear weapons to finally be banned." Most U.S. presidents since Dwight D.
Washington, D.C., June 16, 2010 - U.S. presidents long before President Obama have sought an international fissile material cutoff off treaty but the reasons they have failed remain with us today, according to declassified documents posted today by the National Security Archive. The proposed treaty would cut off the worldwide production of fissile material--plutonium and highly-enriched uranium--for nuclear weapons. (Note 1) According to Dwight D.
Washington, D.C., April 8, 2010 - The new START Treaty signed today in Prague represents "real" but "modest" cuts in strategic nuclear forces comparable to some Cold War alternatives but still higher than the most far-reaching proposals considered by Presidents Reagan and Carter, according to documents posted today by the National Security Archive.
Washington, D.C., January 15, 2010 - To refute early 1960s novels and Hollywood films like Fail-Safe and Dr. Strangelove which raised questions about U.S. control over nuclear weapons, the Air Force produced a documentary film--"SAC [Strategic Air Command] Command Post"--to demonstrate its responsiveness to presidential command and its tight control over nuclear weapons.
Washington, D.C., October 13, 2009 - The election of the new Democratic Party government in Japan led by Yukio Hatoyama raises a significant challenge for the Obama administration: the status of secret agreements on nuclear weapons that Tokyo and Washington negotiated in 1960 and 1969. For years, the ruling Liberal Democratic Party claimed that there were no such agreements, denying, for example, allegations that they had allowed U.S. nuclear-armed ships to sail into Japanese ports. Nevertheless, declassified U.S.
Washington, DC, September 22, 2009 - Sixty years ago this week, on 23 September 1949, President Harry Truman made headlines when he announced that the Soviet Union had secretly tested a nuclear weapon several weeks earlier. Truman did not explain how the United States had detected the test, which had occurred on 29 August 1949 at Semipalatinsk, a site in northeastern Kazakhstan. Using declassified material, much of which has never been published, this briefing book documents how the U.S. Air Force, the Atomic Energy Commission, and U.S.
Washington, D.C., January 13, 2009 - During the 1970s the Shah of Iran argued, like current Iranian leaders today, for a nuclear energy capability on the basis of national "rights," while the Ford and Carter administrations worried about nuclear weapons possibilities, according to newly declassified documents published today by the National Security Archive for the first time.
Washington, D.C., January 12, 2009 - The U.S. government’s secret nuclear bomb squad evaluated more than 100 nuclear extortion threats and incidents between 1974 and 1996 but only a dozen required actual deployments (the others were hoaxes), according to the new book, Defusing Armageddon, and key primary sources posted today in the National Security Archive's "Nuclear Vault" by Archive senior fellow Jeffrey T. Richelson.
