On Thursday the New America Foundation hosted Ward Wilson, winner of the 2008 Doreen and Jim McElvany Nonproliferation Challenge, to examine the underpinnings of nuclear deterrence theory. Joined by Jeffrey Lewis, Director of the Nuclear Strategy and Nonproliferation Initiative, Wilson challenged the belief that nuclear weapons continue to serve a useful purpose in the world. An MP3 audio recording can be downloaded below, while video is available at right. Wilson's argument framed nuclear weapons in the… more

As the 63rd anniversary of the atomic bombing of Hiroshima and Nagasaki approaches, the world continues to face a litany of nuclear concerns. There is the failure to safeguard all the nuclear material lying loose around the globe. And proponents of nuclear power have gained ground as a result of the current energy crisis.

But the radioactive rhetoric printed on newspaper opinion pages and proclaimed from would-be presidential podiums puts Iran at the top of the nuclear list.

"Bomb, Bomb Iran," sang John McCain -- the man running for President… more

Nuclear deterrence is a rather subjective concept: How many weapons are enough to ensure deterrence? How difficult is it to achieve and maintain deterrence? How important are the technical details of a country’s nuclear forces, such as the size, configuration, and readiness, to the goal of maintaining deterrence? The answers to these questions vary across recent history and across geographic areas.

One view, I would say the dominant view in U.S. defense planning, is that deterrence can be achieved only through… more

Most scholars and policymakers favor stemming the tide of nuclear proliferation, even as they acknowledge the pacifying effects of established nuclear arsenals on great power relations. When it comes to nuclear arsenals, how robust must a country's nuclear arsenal be--how much is enough? Some of the key variables in existing studies - e.g., the nuclear "balance of power" - have been poorly conceived, and the data used to measure the nuclear balance and its effect on policy has come from… more

On April 9th, Jeffrey Lewis, director of the Nuclear Strategy and Nonproliferation Initiative, hosted James Acton, a Lecturer in the Centre for Science and Security Studies in the Department of War Studies at King's College London for a talk entitled "Nuclear Mind Reading: Iran's Nuclear Intentions and the IAEA". Acton analyzed the IAEA's ability to assess states' intent—as opposed to their capabilities—and then asked what the IAEA means when it announces that an issue is “no longer considered to be… more

The Department of Energy (DOE) plans to undertake an extensive, multi-billion dollar investment in new nuclear weapons facilities and new nuclear warhead designs. The initiative, known as “Complex Transformation,” is unnecessary on strategic and technical grounds, not to mention exorbitantly expensive. The various plans being considered by the DOE have more to do with bailing out the nuclear weapons industry than they do with determining what size complex makes sense in an era of nuclear arms reductions. At a minimum,… more

The next President will conduct yet another Nuclear Posture Review -- the third since the end of the Cold War. What's the point? Will it be any different or just more of the same? At this May 20 New America event, Dr. Janne Nolan tackled these tough questions and others. Dr. Nolan, currently a professor of international affairs at the University of Pittsburgh, is author of An Elusive Consensus: Nuclear Weapons and American Security after the Cold War, considered… more

Before China carried out an anti-satellite test in January 2007, some U.S. policy-makers, including NASA Administrator Michael Griffin and the U.S. House China Working Group, advocated greater cooperation between the United States and China in space. After the test, which created a massive cloud of space debris that angered international space professionals and alarmed the American public, increased references to U.S.-China competition and hints of a new space race drowned out calls for cooperation. Using the experience they… more

For many Americans, nuclear weapons bring up old memories and forgotten associations -- the duck and cover drills of the 1950s, President Reagan's exhortations against the "evil empire," and the plot lines of countless straight-to-video political thrillers. It may then come as a surprise that in 2008 the United States is considering a huge new investment in nuclear weapons.

The U.S. Department of Energy's National Nuclear Security Administration is pushing for an estimated $150 billion to develop a new generation of… more

Nuclear terrorism is an urgent threat, but policy debates have been dangerously dominated by caricatured depictions of terrorist groups and potential plots. In his latest book, On Nuclear Terrorism, Michael Levi argues that an obsession with worst-case scenarios and finding perfect defenses has blinded us to important opportunities to confront the nuclear threat.

On Jan. 30, the Nuclear Strategy & Nonproliferation Initiative drew together Levi and New America’s Priscilla Lewis and Jeffrey Lewis to engage in a discussion of… more
