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.

From July 11-12, 2023, NATO leaders gathered in Vilnius, Lithuania for one of the most significant NATO summits in history. This timely brief by Eric Rosenbach, Grace Jones, and Olivia Leiwant serves as a background piece on Ukraine’s history with NATO, potential future pathways for accession, and the operational impact Ukraine’s NATO membership could have on the alliance. 

Policymakers need to act now and place child welfare professionals, not law enforcement actors, at the border to effectively screen and interview migrant children. Information sharing practices need to be improved, with a movement away from paper documents that can easily get lost to an approach that is digital, secure, and accessible by the child, their guardian, their lawyer, and their doctor. Further, the enforcement processing facilities need to undergo an immediate infrastructural transformation with the addition of new design features that are necessary and sensitive to the majority demographic that are held within facilities—children and families.

These actions are doable and require no legislative action. Migrant children deserve decisive action to ensure that their health, safety, and well-being is not jeopardized as they seek refuge in the United States.

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.

Despite the far-reaching effects of the current pandemic,  the essential nature of world politics will not be transformed. The territorial state will remain the basic building-block of international affairs, nationalism will remain a powerful political force, and the major powers will continue to compete for influence in myriad ways. Global institutions, transnational networks, and assorted non-state actors will still play important roles, of course, but the present crisis will not produce a dramatic and enduring increase in global governance or significantly higher levels of international cooperation. In short, the post-COVID-19 world will be less open, less free, less prosperous, and more competitive than the world many people expected to emerge only a few years ago.

In this first publication of the Belfer Center Homeland Security Project Paper Series, Alan Bersin and Nate Bruggerman write about the dramatic changes in numbers of migrants crossing the border between the U.S. and Mexico and the urgent need for attention and response from the U.S. Congress and executive branch of the government.

At 70, NATO remains the single most important contributor to security, stability and peace in Europe and North America. NATO allies, however, are confronting daunting and complex challenges that are testing both their purpose and unity. NATO’s leaders need to act decisively in 2019 to meet these tests and heal the widening divisions within the Alliance before it is too late.
