Nuclear Issues

Assaf Zoran argues that an attack on Iran's nuclear facilities may have the opposite result of prompting an escalation in Iran’s nuclear developments, a pattern previously observed in response to kinetic actions attributed to Israel.

Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

Kari A. Bingen and Heather W. Williams write that if Russia plans to deploy nuclear weapons in space to target satellites, the threat is definitely serious—and the U.S. should act fast.

This year's G7 summit in Hiroshima sees nuclear disarmament and non-proliferation sitting high on the agenda, amid rising tensions between the nuclear states and an increasingly divided international order.  Six contributors offer their analyses, including the Belfer Center's Mayumi Fukushima.

Abolghasem Bayyenat argues that without the JCPOA restrictions in place, Iran's nuclear program will expand and continue to acquire irreversible technical knowledge and competencies.

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.

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.

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.

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.
