Gender Analysis and the Treaty on the Prohibition of Nuclear Weapons: A Response to Daarstad, Park, and Balogh

| Dec. 01, 2023

Herzog, Baron, and Gibbons (HBG) thank Haley Daarstad, RyuGyung Park, and Timea Balogh for replicating their 2022 short article in The Journal of Politics. In that article, HBG tested the malleability of U.S. public support for nuclear disarmament, specifically in the context of the 2017 Treaty on the Prohibition of Nuclear Weapons (TPNW). Their survey experiment reveals that––despite majority public support for eliminating nuclear weapons––Americans’ backing of the TPNW can be significantly attenuated by exposure to elite and group cues opposing the treaty. The resultant article has received considerable attention from policymakers and anti-nuclear activists alike. Daarstad, Park, and Balogh (DPB) offer three main substantive points of comment on HGB's article. First, DPB indicate that the results successfully replicate and note that they “do not find any coding errors that undermine the authors’ analysis or conclusions.” Second, DPB show that the findings also replicate when partisan leaners are coded as political Independents. Finally, and most interestingly, DPB conduct gender-based subgroup analysis and show that there are heterogenous treatment effects among male and female respondents in our sample. HBG address each of these points in turn.

United States Entity List: Limits on American Exports

| February 2021

The Economic Diplomacy Initiative (EDI) at the Belfer Center for Science and International Affairs is presenting a first-of-its-kind analysis of the makeup of the Commerce Department’s Entity List, by country, by sector, and by year of addition. Starting with raw data made available by the Commerce Department, we manually grouped blacklisted sub-entities at the parent level to give a clearer view of the companies targeted by export controls. While  the Entity List does not include industry tags, we used Federal Register announcements and secondary research to manually assign industry sectors to each entity. The analysis provides a quantitative review of the evolving use of the entity list to shed light on shifting aims of US economic and national security policy.

Revitalizing Nuclear Security in an Era of Uncertainty

| January 2019

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.

Steps for Rebuilding U.S.-Russian Nuclear Security Cooperation

| July 2017

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.

When Did (and Didn’t) States Proliferate?

| June 2017

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.

American Nuclear Diplomacy

| August 4, 2016

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.

Preventing Nuclear Terrorism: Continuous Improvement or Dangerous Decline?

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.

International Cooperation to Secure Military Nuclear Materials

"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..."

On June 23 and 24, twenty five experts met at Harvard University’s Kennedy School of Government under the auspices of the Geopolitics of Energy Project at the Belfer Center for Science and International Affairs. The group, which included experts from academia, the financial sector, government, and the energy industry, spent an evening and the following full day discussing and debating the possible energy implications of a nuclear deal between the P5+1 and Iran.

Fresh Ideas for the Future: Symposium on the NPT

| April 26, 2015

The abstracts in this booklet summarise the research presented at an academic symposium convened on the sidelines of the 2015 NPT Review Conference. As we write this, journalists and seasoned experts in the nuclear policy field have been speculating about the particularly difficult challenges facing the Review Conference this year. To address those challenges, we would urge all concerned to consider the ideas and analyses presented at this symposium. Experts would be hard-pressed to find a better collection of fresh ideas and approaches for assessing and strengthening the NPT.
