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?
The escalating confrontation between the United States and Iran over the latter’s nuclear program has triggered much debate about what actions should be taken to ensure that Iran does not develop a nuclear weapon. How might certain actions against Iran affect the global economy?
What are the major national security threats facing the United States, and what can the next president do to prepare for a potential disaster? Three days after the 2012 national election, FAS hosted a symposium featuring policy experts who provided recommendations (in memo form) to the Obama administration on how to best respond to catastrophic threats to national security.
NATO’s Deterrence and Defense Posture Review (DDPR) will determine the number and role of the U.S. non-strategic nuclear weapons deployed in Europe and how NATO might work to reduce its nuclear posture as well as Russia’s inventory of such weapons in the future.
In this report, FAS President Charles Ferguson examines the national and international efforts to control and secure radioactive materials.
In the wake of the devastating meltdown at the Fukushima Daiichi Nuclear Power Plant in Japan, many Americans are now reevaluating the costs and benefits of nuclear energy. If anything, the accident underscores that constant vigilance is needed to ensure nuclear safety. Policymakers and the public need more guidance about where nuclear power in the United States appears to be heading.
Ali Vaez and Charles Ferguson co-authored a report analyzing options for establishing an enhanced safeguards system for the Iranian nuclear program.
FAS report addressing security concerns at Pakistan’s nuclear facilities and identifies specific terrorists within Pakistan who are motivated and potentially capable of taking Pakistani nuclear assets.
An overview and technical assessment of the Phased Adaptive Approach (PAA) missile defense system proposed by NATO and the United States.
Though the nuclear arsenal of the United States is smaller than it was during the Cold War, the day-to-day deployment of forces has changed very little. The United States still has weapons ready to launch at a moment’s notice at all times. This report describes how to reduce the nuclear missions to one: a minimal deterrence of nuclear attack.
Nuclear weapons, while simple in principle, are technically complex devices with a multitude of components. As with any complicated piece of equipment, there may be concern that, over time, a weapon’s reliability could decline. To coordinate efforts to maintain the nation’s existing nuclear weapons, the Department of Energy developed a Stockpile Stewardship Program (SSP). This report reviews the status of the experimental devices that support the SSP, describes how each experiment is supposed to work, and identifies the problems that have been encountered.
This report examines the debate over China’s modernization of its nuclear forces, describes past and current U.S. nuclear targeting of China, and uses software to simulate the effects of Chinese and U.S. of nuclear attacks.
