International Security & Defense

Stephen Walt writes that those who favor foreign policy restraint believe the United States should trade and invest in other countries, encourage other states to do the same, and be open to managed immigration instead of building walls in a fit of xenophobia.

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.

Joseph Nye writes that Washington's strategy towards Beijing should be to avoid either a hot or cold war, co-operate when possible and marshal its assets to shape China's external behaviour. This can be done through deterrence and a strengthening of both alliances and international institutions.

Joseph S. Nye writes that following the first Republican debate of the U.S. presidential primary season, there is good reason to worry about what a Republican victory in 2024 would mean for the U.S.-led global order. History suggests that when Americans embrace retrenchment, much more than just liberal internationalist principles suffer for it.

Joseph Nye explores what a second Donald Trump presidency may mean for U.S. foreign policy and the world? While the man himself is unpredictable, his first term and his behavior since losing re-election in 2020 offer plenty of clues, none of which would be comforting to America's allies.

Juliette Kayyem argues that although the emergency social-safety provisions helped those most in need, the use of Title 42 was a brutal and unforgiving policy that essentially ended asylum in the United States.

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.

Joseph Nye writes: From an American perspective, it is just as dangerous to underestimate Chinese power as it is to overestimate it. While hysteria creates fear, discounting China's recent progress and future ambitions could lead the United States to squander its own long-term advantages.

Meghan M. Garrity, an International Security Program postdoctoral fellow at the Harvard Kennedy School's Belfer Center discussed her research on government-sanctioned mass expulsion events at a virtual seminar on November 3, 2022.

According to the U.N. High Commissioner for Refugees, at the end of 2021 nearly 90 million people were forcibly displaced worldwide. What makes Uganda's expulsion of 50,000 Asians distinct? Unlike most displaced people, the Asians expelled from Uganda weren't fleeing conflict or natural disasters. Instead, the forced displacement that year is what political scientists call a mass expulsion. That's when a government implements an ethnically targeted policy to remove a group of people, en masse, without individual legal evaluations and refuses to allow them to return.
