Arms control agreements that envision the verified dismantlement of nuclear weapons require the availability of suitable technology to perform the verification. But they also depend on the good faith of the participants and a shared sense of confidence in the integrity of the verification process. An exercise in demonstrated warhead dismantlement showed that such confidence […]
By Hans M. Kristensen The latest set of so-called New START treaty aggregate data published by the U.S. State Department shows that Russia is continuing to increase the number of nuclear warheads it deploys on its declining inventory of strategic launchers. Russia now has 259 warheads more deployed than when the treaty entered into force in […]
The fact that a now-retired nuclear weapon was once located at a now-closed location in the United States shall no longer be considered classified information, the Department of Defense announced last week. This may seem so trivial and insignificant as to be hardly worth deciding or announcing, but it could have positive practical consequences for […]
CBS’s 60 Minutes program Risk of Nuclear Attack Rises described that Russia may be lowering the threshold for when it would use nuclear weapons, and showed how U.S. nuclear bombers have started flying missions they haven’t flown since the Cold War.
By Hans M. Kristensen The U.S. Air Force today sent two non-nuclear B-1 bombers to overfly South Korea in response to North Korea’s recent nuclear test. The operation coincides with the deployment of two non-nuclear B-1 bombers and a recently denuclearized B-52 bomber to Europe for exercise Ample Strike. To be sure, nuclear bombers continue […]
A longstanding conundrum surrounding efforts to negotiate reductions in nuclear arsenals is how to verify the physical destruction of nuclear warheads to the satisfaction of an opposing party without disclosing classified weapons design information. Now some potential new solutions to this challenge are emerging. Based on tests that were conducted by the Atomic Energy Commission […]
By Hans M. Kristensen and Robert S. Norris China’s nuclear forces are limited compared with those of Russia and the United States. Nonetheless, its arsenal is slowly increasing both in numbers of warheads and delivery vehicles. In our latest FAS Nuclear Notebook on Chinese nuclear forces published in the Bulletin of the Atomic Scientists, we […]
The presidential candidates’ debates will soon occur, and the voters must know where the candidates stand on protecting the United States against catastrophic nuclear attacks. While debating foreign policy and national security issues, the Democratic and Republican candidates could reach an apparent agreement about the greatest threat facing the United States, similar to what happened […]
President’s Message: What Will the Next President’s Nuclear Policies Be? by Charles D. Ferguson The presidential candidates’ debates will soon occur, and the voters must know where the candidates stand on protecting the United States against catastrophic nuclear attacks. Three-Dimensional Arms Control: A Thought Experiment by Heather Williams In order to move beyond old-school arms […]
The George W. Bush Administration is not typically viewed as the paragon of arms control. This was the Administration that withdrew from the Anti-Ballistic Missile (ABM) Treaty in 2002, agreed to the Moscow Treaty that same year with no verification provisions, and generally eschewed traditional approaches to arms control, including negotiations and treaties, as Cold […]
Ever since the United States began developing a missile defense system, the focus has been on pursuing a robust missile defense system. As not much progress has been made on boost phase interception, it becomes mandatory to study a technology that could make the midcourse system of the ballistic missile more vulnerable to enemy missile defense system. […]
The special nature of nuclear energy requires particular safety and security conditions and stronger protective measures. The International Atomic Energy Agency (IAEA), as do other international and regional organizations, provides assessment, but it does not know a great deal about the security status of most Member States. It is necessary to learn of and determine […]
