Kristensen After two years of stalling, the latest New START Treaty aggregate data released today by the State Department indicates that U.S. warhead reductions under the treaty are finally picking up. Russia, which is already below the treaty limit, has been more or less flatlining over the past year. Seen in perspective, however, […]

Kristensen With the ink barely dry on the New START Treaty, Jeff Smith at the Center for Public Integrity reports that the Obama administration has determined that the United States can meet its national and international security requirements with 1,000-1,100 deployed strategic nuclear warheads – 450-550 warheads less than planned under the […]
The United States and Russia have significantly reduced their nuclear arsenals since the end of the Cold War. Russia and the United States currently hold more than 90 percent of the world’s total inventory of nuclear warheads. What can nuclear weapons states do to keep reducing their nuclear weapons stockpiles?
By Hans M. Kristensen Despite enormous reductions of their nuclear arsenals since the Cold War, the United States and Russia retain more than 9,100 warheads in their military stockpiles. Another 7,000 retired – but still intact – warheads are awaiting dismantlement, for a total inventory of more than 16,000 nuclear warheads. This is more than […]

What’s wrong with this picture? Despite NATO’s call for greater nuclear transparency, old-fashioned nuclear secrecy prevents media access to the Nuclear Planning Group. . By Hans M. Kristensen Less than six months after NATO’s Deterrence and Defense Posture Review (DDPR) adopted at the Chicago Summit called for greater transparency of non-strategic nuclear force postures in […]
