Mariana Budjeryn writes: War never stops at the border, especially on a continent like Europe. The European Union absorbed millions of Ukrainian war refugees and poured billions of euros into Ukraine's defenses and economic survival. The war permanently reshaped Europe: its demographics, political economy, and energy architecture are shifting in ways that will have irreversible long-term consequences. All of this is because in a very real sense Ukraine already is inextricably woven into the fabric of Europe: Ukraine’s pain is Europe’s pain and Ukraine’s gain will inevitably be Europe's gain, too.

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.

In the authors' view, neither formal NATO membership nor nuclear weapons are fitting security options for Ukraine in the face of Russian aggression. To secure its borders and achieve sustainable peace and stability in Europe, Ukraine should forge a treaty-based strategic alliance directly with the United States.

Abolghasem Bayyenat and Sayed Hossein Mousavian advise the United States and Iran to aim for reaching a modus vivendi that keeps their political conflict within manageable limits. Otherwise, another round of dangerous mutual escalation in the illusory hope of building leverage and extracting more concessions from each other is inevitable.     

While U.S. sanctions have caused Iran’s economy major challenges and limited Iran’s access to financial resources, they have not succeeded in changing Tehran’s behavior regarding its nuclear program. Indeed, Iran has not offered additional concessions. Instead, it has engaged in its own leverage-building strategy by ramping up its nuclear activities, missile program, and regional activities. Iran is not only closer to having the capacity to build a bomb, but even the political discourse of key officials on whether to cross that threshold has been shifting.

Joel Clement argues that the Arctic is now the epicenter for the  Trump administration's full-on assault on scientific integrity.

Horizontal nuclear proliferation presents what is sometimes referred to as the "Nth country problem," or identifying which state could be next to acquire nuclear weapons. Nuclear fuel cycle technologies can contribute to both nuclear power generation and weapons development. Consequently, observers often view civilian nuclear programs with suspicion even as research on nuclear latency and the technological inputs of proliferation has added nuance to these discussions. To contribute to this debate, the author puts forth a simple theoretical proposition: En route to developing a civilian nuclear infrastructure and mastering the fuel cycle, states pass through a proliferation "danger zone."

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.

Matthew Bunn and Steven E. Miller reflect on the late Martin B. Malin, who lost his battle with cancer in April 2020.

The study of existential risk — the risk of human extinction or the collapse of human civilization — has only recently emerged as an integrated field of research, and yet an overwhelming volume of relevant research has already been published. To provide an evidence base for policy and risk analysis, this research should be systematically reviewed. In a systematic review, one of many time-consuming tasks is to read the titles and abstracts of research publications, to see if they meet the inclusion criteria. The authors show how this task can be shared between multiple people (using crowdsourcing) and partially automated (using machine learning), as methods of handling an overwhelming volume of research.
