The Low-Yield Nuclear Warhead: A Dangerous Weapon Based on Bad Strategic Thinking

In the unintuitive world of nuclear weapons strategy, it’s often difficult to identify which decisions can serve to decrease the risk of a devastating nuclear conflict and which might instead increase it. Such complexity stems from the very foundation of the field: Nuclear weapons are widely seen as bombs built never to be used. Historically, granular—even seemingly mundane—decisions about force structure, research efforts, or communicated strategy have confounded planners, sometimes causing the opposite of the intended effect.

Accumulating Evidence Using Crowdsourcing and Machine Learning: A Living Bibliography about Existential Risk and Global Catastrophic Risk

The study of existential risk — the risk of human extinction or the collapse of human civilization — has only recently emerged as an integrated field of research, and yet an overwhelming volume of relevant research has already been published. To provide an evidence base for policy and risk analysis, this research should be systematically reviewed. In a systematic review, one of many time-consuming tasks is to read the titles and abstracts of research publications, to see if they meet the inclusion criteria. The authors show how this task can be shared between multiple people (using crowdsourcing) and partially automated (using machine learning), as methods of handling an overwhelming volume of research.

The Need for Creative and Effective Nuclear Security Vulnerability Assessment and Testing

Realistic, creative vulnerability assessment and testing are critical to finding and fixing nuclear security weaknesses and avoiding over-confidence. Both vulnerability assessment and realistic testing are needed to ensure that nuclear security systems are providing the level of protection required. Systems must be challenged by experts thinking like adversaries, trying to find ways to overcome them. Effective vulnerability assessment and realistic testing are more difficult in the case of insider threats, and special attention is needed. Organizations need to find ways to give people the mission and the incentives to find nuclear security weaknesses and suggest ways they might be fixed. With the right approaches and incentives in place, effective vulnerability assessment and testing can be a key part of achieving and sustaining high levels of nuclear security.

The Risks and Rewards of Emerging Technology in Nuclear Security

Nuclear security is never finished. Nuclear security measures for protecting all nuclear weapons, weapons-usable nuclear materials, and facilities whose sabotage could cause disastrous consequences should protect against the full range of plausible threats. It is an ongoing endeavor that requires constant assessment of physical protection operations and reevaluation of potential threats. One of the most challenging areas of nuclear security is how to account for the impact–positive and negative—of non-nuclear emerging technologies. The amended Convention on the Physical Protection of Nuclear Material (amended CPPNM) states it should be reviewed in light of the prevailing situation, and a key part of the prevailing situation is technological evolution. Therefore, the upcoming review conference in 2021, as well as any future review conferences, should examine the security threats and benefits posed by emerging technologies.

The Past and Potential Role of Civil Society in Nuclear Security

Civil society has played a very important role in nuclear security over the years, and its role could be strengthened in the future. Some nuclear organizations react against the very idea of civil society involvement, thinking of only one societal role—protesting. In fact, however, civil society has played quite a number of critical roles in nuclear security over the years, including highlighting the dangers of nuclear terrorism; providing research and ideas; nudging governments to act; tracking progress and holding governments and operators accountable; educating the public and other stakeholders; promoting dialogue and partnerships; helping with nuclear security implementation; funding initial steps; and more. Funding organizations (both government and non-government) should consider ways to support civil society work and expertise focused on nuclear security in additional countries. Rather than simply protesting and opposing, civil society organizations can help build more effective nuclear security practices around the world.

Assessing Progress on Nuclear Security Action Plans

Participants at the final Nuclear Security Summit in 2016 agreed on “action plans” for initiatives they would support by five international organizations and groups—the International Atomic Energy Agency, the Global Initiative to Combat Nuclear Terrorism, INTERPOL, the United Nations, and the Global Partnership Against the Spread of Weapons and Materials of Destruction. These institutions were supposed to play key roles in bolstering ongoing nuclear security cooperation after the summit process ended. The action plans were modest documents, largely endorsing activities already underway, and there have been mixed results in implementing them. To date, these organizations have not filled any substantial part of the role once played by the nuclear security summits.

Secrecy, Public Relations and the British Nuclear Debate

The opening of the British archives has seen historians uncover the secrets of the UK's nuclear weapons programme since the 1990s. While a growing number have sought to expose these former secrets, there has been less effort to consider government secrecy itself. What was kept a secret, when and why? And how and why, notably from the 1980s, did the British government decide to officially disclose greater information about the British nuclear weapons programme to Members of Parliament, journalists, defence academics and the tax-paying general public.

Public Testimony on Trump Administration Funding for Nuclear Theft Preventing Programs

A nuclear explosion detonated anywhere by a terrorist group would be a global humanitarian, economic, and political catastrophe. The current COVID-19 pandemic reminds us not to ignore prevention of and preparation for low-probability, high-consequence disasters. For nuclear terrorism, while preparation is important, prevention must be the top priority. The most effective strategy for keeping nuclear weapons out of the hands of terrorists is to ensure that nuclear materials and facilities around the world have strong and sustainable security. Every president for more than two decades has made strengthening nuclear security around the globe a priority. This includes the Trump administration, whose 2018 Nuclear Posture Review states: “[n]uclear terrorism remains among the most significant threats to the security of the United States, allies, and partners.”

Putin’s Remarks on Use of Nuclear Weapons Are Confusing, But Unlikely to Constitute a Shift in Nuclear Posture

Russian President Vladimir Putin’s eschatological talk of nuclear Armageddon at this year’s Valdai forum has stirred up heated debates on how well his description of Russia’s potential use of nuclear weapons matches the country’s official military doctrine. However, a close look at Putin’s Oct. 18 remarks and Russia’s 2014 military doctrine reveals that, while Putin deviated from the language in the doctrine, he did not lie on the first use issue. Nor did he seem to be hinting at a shift in Russia’s nuclear posture. More likely, he was signaling to Washington that the existing nuclear arms control treaties need to remain in place for the sake of ensuring strategic stability in the U.S.-Russian nuclear dyad and avoiding an accidental war between the two countries.

The INF Quandary: Preventing a Nuclear Arms Race in Europe. Perspectives from the US, Russia and Germany

Thus, the fate of the INF Treaty is of surpassing importance in Europe, Russia and the United States. The stakes for the parties to the treaty are obvious.

Below, three authors representing each of these perspectives consider the likely future of the treaty, how it might be saved and what its demise might mean.
