Why Biden’s New Nuclear Security Agenda Might Not Work as Planned

| Apr. 04, 2023

Early in March, the Biden administration unveiled its 19th National Security Memorandum. While the operational part of this memorandum is classified, the White House shared a factsheet on the new strategy, which is centered around three main pillars: countering weapons of mass destruction terrorism, advancing nuclear material security, and improving radioactive material security. The three-pronged strategy aims to reinvigorate long-standing approaches to risks from weapons of mass destruction (WMD) and nuclear security and introduce new ways to deal with emerging threats.

Russia’s “dirty bomb” disinformation, annotated

| Dec. 01, 2022

In late October, after eight months of war, the Russian government claimed that Ukraine was preparing to use a "dirty bomb" and blame it on Russia. There was never any evidence for this claim. But Russia's ambassador to the UN, Vassily Nbenzia, nevertheless sent a letter (reproduced below) demanding that the Security Council hold a meeting to discuss the "dirty bomb" issue.

Russia's claims have been widely dismissed. Nevertheless, Russian spokesmen are continuing to press the narrative.  (See, for example, the November 8 statement from Anatoliy Antonov, Russia's ambassador to the United States, which slurs together with the dirty bomb theme a variety of other false claims about Ukraine.) It seems worthwhile, therefore, to debunk Russia's claims in detail.

Poll: Americans, Japanese, and South Koreans Don't Support Using Nuclear Weapons Against North Korea

| Oct. 25, 2022

For months, evidence has accumulated that North Korea may be preparing its seventh nuclear explosive test. Continuous warnings by analysts and the media about this possibility are a sobering reminder that Pyongyang's continued pursuit of a larger nuclear arsenal remains a challenge for the Non-Proliferation Treaty and the nonproliferation regime. This continues to be the case even as the public and leaders around the world have largely shifted their attention to the nuclear dimensions of the war in Ukraine.

Switzerland’s wait-and-see approach to nuclear ban treaty is sensible

| July 21, 2022

From June 21-23, dozens of countries gathered in Vienna to discuss how to implement the new UN Treaty on the Prohibition of Nuclear Weapons (TPNW)External link. They were joined by nuclear disarmament activists from around the world, including hibakusha – atomic bombing survivors from Hiroshima and Nagasaki. Swiss diplomats were also present, but only to observe rather than directly participate. This may seem surprising, but it’s consistent with Switzerland’s pragmatism on questions of nuclear abolition.

Switzerland’s decision was based on careful study. Following a report by an interdepartmental working groupExternal link, the government opted not to become a TPNW member in 2018 and 2019. Instead, the country wants to work on nuclear disarmament with states inside and outside the treaty. Practically speaking, this means sending Swiss experts to observe TPNW proceedings. And that engagement is a good thing because the nuclear ban treaty is here to stay and cannot be ignored.

What We Got Wrong about Nuclear Risk Reduction

| May 23, 2022

Existing risk reduction tools are designed to prevent risks associated with misperception or inadvertent escalation. They are not tailored to the type of intentional escalation and risk-taking that Russian President Vladimir Putin has demonstrated with regards to Ukraine. Preventing further escalation and nuclear use will require strengthening deterrence and developing new risk reduction tools.

Five reasons that Russia’s nuclear exports will continue, despite sanctions and the Ukraine invasion. But for how long?

| May 17, 2022

By many measures, Russia’s state-controlled nuclear energy company, Rosatom, has primacy in the global nuclear energy market. At any given moment, the firm provides technical expertise, enriched fuel, and equipment to nuclear reactors around the world. The Russian invasion of Ukraine and, more acutely, the Russian military’s dangerous actions at the Zaporizhzhia nuclear power plant and in the Chernobyl exclusion zone have many countries rethinking their dependence on Russian nuclear products and searching for alternatives. Additionally, the ensuing global effort to cripple Russian access to international markets calls into question the viability of current contracts, government licensing, and financial instruments involved in Russia’s nuclear exports.

L’invasione dell’Ucraina e il rischio nucleare.

| Apr. 19, 2022

La mia valutazione dei possibili rischi di uso di armi non convenzionali (anche tattiche nucleari) nel conflitto in Ucraina deriva in parte da precedenti storici importanti e in parte dalla mia esperienza diplomatica. Mi spiego meglio. Se guardiamo alla storia dei rischi nucleari, vediamo che in altri conflitti, paesi con armi atomiche hanno minacciato il loro uso per portare a conclusione il conflitto a loro vantaggio. L’amministrazione Eisenhower per esempio contemplò l’utilizzo di armi atomiche nel conflitto coreano per scoraggiare l’intervento della Cina. Israele nella famosa guerra dello Yom Kippur nel 1973 minacciò esplicitamente l’uso di armi nucleari per deterrenza nei confronti dell’invasione delle truppe arabe. In questi conflitti, tuttavia, i paesi con armi atomiche sono riusciti poi a prevalere con armi convenzionali e senza il ricorso alle armi nucleari. Abbiamo avuto altri conflitti che hanno coinvolto paesi con armi atomiche – l’Unione Sovietica in Afghanistan e l’America in Iraq – dove i paesi con arsenali atomici alla fine sono stati sconfitti ma non hanno fatto ricorso alle armi atomiche.

Attacco Nucleare di Putin? Ora Basta Un Piccolo Incidente.

| Apr. 04, 2022

Il rischio atomico resta alto. Ce lo conferma un'esperta del settore, la professoressa Francesca Giovannini, direttrice esecutiva del Project on Managing the Atom presso il Belfer Center della Harvard University e già collaboratrice della CTBTO, l'organo con sede a Vienna che vigila sulla messa al bando dei test atomici.
