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.

Stephen Walt explains why Putin understood that Ukraine's fate was more important to Russia than it was to the West.

Stephen Walt offers a tentative and far-from-comprehensive survey of what scholars have to say about the war in Ukraine.

Joseph Nye argues that prudence results from the fear of creating unintended consequences in unpredictable systems and can develop into a norm of nonuse or limited use of certain weapons or a norm of limiting targets. Something like this happened with nuclear weapons when the superpowers came close to the brink of nuclear war in 1962, during the Cuban missile crisis. The Limited Test Ban Treaty followed a year later.

Jayita Sarkar explains why the Biden administration needs to re-conceptualize nuclear terrorism and act quickly.

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 arguments in favor of the United States' declaring that the only purpose of its nuclear weapons is to deter others who possess them from using theirs — in other words, that in no circumstances will this country use nuclear weapons first — are far stronger than the arguments against this stance. It must be hoped that the next US administration will take this no-first-use step promptly.

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.

The move of President Donald Trump to visit Baghdad on Wednesday is a small, good one, amid a week of calamitous decisions. The press will understandably highlight the time that Trump spends with U.S. troops. Yet a key objective of the trip will have been to shore up the new Iraqi government's confidence in the U.S., as Iraqi officials must be high on the list of those shocked by the president’s recent decisions to rapidly withdraw U.S. forces from Syria and Afghanistan. Perhaps the president has realized that his administration has some hard work to do if there is any hope of keeping his latest determinations from dramatically strengthening Iran.
