The Doomsday Clock is an internationally recognized design that conveys how close we are to destroying our civilization with dangerous technologies of our own making. First and foremost among these are nuclear weapons, but the dangers include climate-changing technologies, emerging... Read More
Russia has taken important steps in modernizing its nuclear forces since early 2013, including the continued development and deployment of new intercontinental ballistic missiles (ICBMs), construction of ballistic missile submarines, and development of a new strategic bomber.
In this interview, former Los Alamos National Laboratory director Siegfried S. Hecker details one of the world’s great nonproliferation stories—the effort to secure the Semipalatinsk Test Site in Kazakhstan.
Russia is in the middle of modernizing its nuclear forces, replacing Soviet-era ballistic missiles with fewer improved missiles. In a decade, almost all Soviet-era weapons will be gone, leaving a smaller but still effective force that will be more mobile than what it replaced.
In this Nuclear Notebook, the authors write about nonstrategic nuclear weapons—starting with the difficulty of finding a universal definition for them. Although the United States and Russia have reduced their nonstrategic stockpiles, significant inventories remain.
Despite the promise of a more transparent future after Russia's ratification of New START in January 2011, the international community’s ability to monitor developments in Russia’s nuclear forces has become more difficult because the Kremlin does not release full aggregate treaty numbers of the
In this Nuclear Notebook the authors highlight the key milestones and facts regarding the nuclear pursuits of the first five states to develop nuclear weapons—the United States, the Soviet Union and Russia, Britain, France, and China.
With Russia’s ratification of New START in January 2011 comes a commitment to bilateral nuclear reductions. With a 2018 deadline as the goal, the treaty sets out to limit the number of deployed strategic nuclear warheads and the number of deployed ballistic missiles and heavy bombers.
As the writers in this symposium illustrate, dealing with Iran’s
nuclear program is one of the most important foreign policy issues of the day.
Years of stalled talks, diplomatic dead-ends, and sanctions have made it
Missile defenses have been a source of contention in US-Russian relations since
the beginning of the strategic dialogue between the United States and the Soviet
Union. Almost every nuclear arms reduction treaty has involved tough
At the same time as major powers are saying that they want to rein in nuclear
proliferation, they are offering both nuclear energy programs and conventional
weapons to client states. Military arms sales may shore up certain
The authors show that the United States has the ability to defend itself from long-range nuclear armed ballistic missiles if it builds the right systems—defenses based on stealthy drones that could shoot down ballistic missiles in powered flight after they have been launched from fixed known sit
