Nuclear Issues

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.

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.

Until now, nuclear weapons have largely been in the background of the Ukraine conflict. That changed when Russian President Vladimir Putin elevated Russia’s military status to ‘special service regime’, including its nuclear forces. In practice, this ‘special status’ could mean higher readiness and survivability of the Russian nuclear command authority along with its nuclear forces.

Putin is a nuclear bully. He has much more at stake in Ukraine than NATO does and is willing to escalate the crisis to get his way. None of this is new. What this announcement signals, however, is two things: resistance to the Russian invasion is hurting, and Putin is getting desperate. While the first point should inspire hope for Ukraine and Europe, the second necessitates caution because options for a face-saving resolution to the crisis, without resorting to massive casualties, are dwindling for Putin. But there are still a few off-ramps left, and NATO can also play a role in reducing risks of further escalation.

The initial stage of the war in Ukraine has confounded expectations. Russia’s military invasion failed in key objectives, upending predictions of a rout of Ukraine. Then, after years of avoiding direct confrontations with Moscow, Western nations are now directly punishing Russian President Vladimir Putin and his allies with truly devastating economic sanctions while openly supplying arms to Ukraine.

Though there were peace talks for the first time on Monday, there are no signs that the cycle of escalation will go down. Amid unprecedented global pressure, Putin is doubling down on a defensive posture that pits Russia against almost everyone else in the world. He has ratcheted up the levels of violence in eastern Ukraine, bombarding the city of Kharkiv with suspected cluster munitions, while putting the country’s nuclear arsenal on alert.

Nuclear experts are trained to think the unthinkable. So, here is an unthinkable scenario that might actually happen in real life:

The battle over Ukraine drags on. From both the European Union and the United States, fresh weapons and other supplies continue to enter into Ukraine and allow the Ukrainian forces to fight on. The battle reaches what conflict resolution expert William Zartman calls “a hurting stalemate” situation. The balance of forces on the ground is not completely or perfectly symmetrical, but what was once considered a completely disproportioned asymmetry of forces has been gradually re-equilibrated, in favor of the Ukrainian forces.

No great breakthroughs or dramatic developments were expected at the Biden-Putin summit, and none was achieved. But the message was clear: There is a new sheriff in town. Putin noticed, describing Biden as very different from Trump—experienced, balanced, and professional.

The Bulletin of Atomic Scientists has published a document from the Pugwash Conference on Science and World Affairs concerning nuclear problems and tensions in the time of COVID-19. The document has been co-signed by a large number of Pugwash colleagues and personalities.

The world will soberly commemorate the 33rd anniversary of the Chernobyl nuclear power plant catastrophic accident on Friday, April 26, 2019.  Some may wonder why bother with a gone-by historical event that happened in a distant land — a country that no longer exists — the former Soviet Union (now Ukraine).  On the contrary, Chernobyl and its legacy, with its specters of lingering human toll, radiation contamination, and the massive new shelter ("New Safe Confinement") installed over the old sarcophagus encasing the reactor, will be with us for a long time.
