Nuclear Issues

Nuclear security around the world has improved dramatically over the last three decades—which demonstrates that with focused leadership, major progress is possible. But important weaknesses remain, and the evolution of the threat remains unpredictable. The danger that terrorists could get and use a nuclear bomb, or sabotage a major nuclear facility, or spread dangerous radioactive material in a “dirty bomb,” remains too high. The United States and countries around the world need to join together and provide the leadership and resources needed to put global nuclear security on a sustained path of continuous improvement, in the never-ending search for excellence in performance.

A new study from the Center for a New American Security (CNAS) examines the challenges to strategic stability between the United States and Russia and proposes a series of recommendations for navigating the dangers ahead.

Cooperation between U.S. and Russian nuclear scientists and engineers represents an important opportunity for rebuilding U.S.-Russian relations. The United States and Russia possess more than 90 percent of the world’s nuclear weapons, the world’s largest stocks of weapons-usable nuclear material, and the world’s largest nuclear complexes, giving them a special responsibility for nuclear security and preventing nuclear terrorism.

In this Project on Managing the Atom Discussion Paper, Philipp C. Bleek chronicles nuclear weapons proliferation choices throughout the nuclear age. Since the late 1930s and early 1940s, some thirty-one countries are known to have at least explored the possibility of establishing a nuclear weapons program. Seventeen of those countries launched weapons programs, and ten acquired deliverable nuclear weapons.

On 24 and 25 November 2016 experts from politics and academia, including FDP Executive director Cathryn Clüver, discussed the impact of Brexit on several policy areas in a series of workshops at the Hertie School of Governance in Berlin. All events took place under Chatham House rules.

In this report, American Nuclear Diplomacy: Forging a New Consensus to Fight Climate Change and Weapons Proliferation, Former Deputy Secretary of Energy and Belfer Center Senior Fellow Daniel Poneman writes that we face two existential threats: nuclear annihilation and catastrophic climate change. Each, he says, stems from human origins. Both must be fought aggressively.

"Multiple studies confirm the grim truth that, even if all nations fulfill their Paris Climate Agreement emissions pledges, the world will still far overshoot the 2°C warming limit scientists say we must not exceed to prevent devastating climate impacts. Carbon-free nuclear energy can help close the gap. But can we expand its environmental benefits without increasing the risks of nuclear terror?"

Poneman outlines a diplomatic strategy and tough-minded, bipartisan policies to get us there.

While the issue of cyber operations beyond NATO’s own networks is a politically difficult one given the complex mosaic of national, transnational (EU), and international law; the role of national intelligence efforts in certain types of operations; and ever-present disputes over burden-sharing, the Alliance already has invaluable experience in developing policies and procedures for contentious and sensitive tools in the form of the Nuclear Planning Group (NPG). This article begins with a brief overview of actions NATO has already taken to address cyberthreats. It will then explore why these, while important, are insufficient for the present and any imaginable future geopolitical threat environment. Next, it will address the history of the NPG, highlighting some parallels with the present situation regarding cyber and drawing out the challenges faced by, and activities and mechanisms of, the NPG. Finally, it will make the case that a group modeled on the NPG can not only significantly enhance the Alliance’s posture in cyberspace, but can serve as an invaluable space for fostering entente and reconciling differences on key aspects of cyber policy. It concludes that the Alliance needs to consider offensive cyber capabilities and planning, and it needs a Cyber Planning Group to do it.

In this new report, Preventing Nuclear Terrorism: Continuous Improvement or Dangerous Decline?, Matthew Bunn, Martin Malin, Nickolas Roth, and William Tobey provide a global reality check on nuclear security. They note that effective and sustainable nuclear security capable of addressing plausible threats is the single most effective chokepoint preventing terrorists from acquiring a nuclear weapon.

"One category of nuclear material that has not yet been adequately addressed throughout recent Nuclear Security Summits is military stockpiles.2 Instead, the Summit process has focused primarily on reducing the risk of civilian nuclear material theft..."
