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.

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.

The world has grown more dangerous but also less open to arms control measures that could limit some of the dangers. What can be done? Steven E. Miller offers a tour de force overview of both dismal and hopeful trends within arms control over the past decades, in this first paper of a new HCSS series on Arms Control.

Joel Clement details the concerns surrounding the use of solar geoengineering to mask the effects of climate change and argues for using existing technology to quickly transition away from fossil fuels.

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.

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.

2021 Arctic Frontiers hosted a panel of young Arctic leaders alongside seasoned Arctic influencers who dove deeper into the opportunities and obstacles northern youth face now and in the future. Framed in the context of the UN's Sustainable Development Goals, speakers were invited to discuss the pressing issues that they stand to inherit such as climate change, societal pressure, migration of young people to the south, and the question of whether the Arctic is facing its own cultural revolution. This session sought to build bridges between generations, borders, and disciplines to find the best solutions for a resilient Arctic.

In recent years, NATO has begun to incorporate some innovative new cyberwarfare games and exercises into its annual wargames. But there is something missing. If NATO wants to see what nation-state hacking is like in the chaotic multiactor online world, it needs to practice fending off some actual hackers.
