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.

Mariana Budjeryn's Inheriting the Bomb tells the story of how Ukraine came into possession of the world's third-largest nuclear arsenal—larger than the combined stockpiles of China, France, and the United Kingdom at the time—and decided to disarm peacefully a few years later. Ukraine's denuclearization was far from a straightforward process. After initially renouncing nuclear weapons, Ukrainian officials sought recognition that their newly independent country was a rightful heir to part of the Soviet cache, deserving of equal treatment, financial compensation, and pledges that disarmament would not endanger Ukraine's security. 

David M. Allison argues that in ascending order of predictive power, warnings of an imminent nuclear strike would come from Russian whistleblowers, the U.S. intelligence community, and Putin himself.

Joseph Nye argues hat the major threat to U.S. power comes from its internal divisions. These are serious liabilities but they were not created by the invasion of Ukraine.

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.

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.

The nuclear arms control architecture that underwrites European security is crumbling. Europe cannot achieve global nuclear disarmament or build its own credible deterrent, but it can clear the path for the next generation of arms governance through joint action. 

Rebecca Davis Gibbons writes that having a full appreciation of the consequences of nuclear weapons and their place in society means learning from the stories of the survivors of Hiroshima and Nagasaki—but also from the stories from other survivors of nuclear explosions: those who lived and worked adjacent to testing sites in Algeria, French Polynesia, Australia, the United States, France, the Republic of the Marshall Islands, Western China, and Kazakhstan.

Polls in the United States and nine allied countries in Europe and Asia show that public support for a nuclear test is very low. If the Trump administration conducts a test, then it shouldn't expect backing from Americans or its closest U.S. partners.
