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.

Stephen Walt argues that Henry Kissinger's concerns about the destabilizing impact of ideas made him hypersensitive to the smallest perturbations in strategically marginal countries and inclined him to overreact to them in ways that other realists opposed.

Stephen Walt analyzes how the war in Gaza will have widespread geopolitical effects.

Stephen Walt analyzes the costs and benefits of forming alliances. When powerful and stable states face the same threats that the United States does, forming an alliance with them makes good sense. Adding weak and vulnerable members to an alliance may not strengthen it, and long-standing partnerships become less effective if some members let their own military capabilities languish. Another problem with the overzealous pursuit of new partners is the possibility that their agendas will be incompatible with those of the United States.
