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.

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.

Gabrielle Armstrong-Scott and Jim Waldo argue that machine learning tools and a better definition of "terrorist and extremist content" could help make the Web a safer place.

Technology companies and governments have spent the past decade trying to better address the evolving threat of terrorist and violent extremist content online (TVEC). This paper examines how effective these efforts have been, where we are today in managing the problem, and wherein lie gaps for improvement.

This paper will review the changing world of climate change education and opportunities for adopting innovative pedagogical approaches such as immersive technologies, participatory methods, and art-based learning.

The Biden-Putin summit in Geneva did not disappoint the very low expectations set out for it. To move beyond symbolism and signaling, however, the Biden-Putin proclamation has to be translated into practical progress.

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.

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