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.

After a century of rebellion, South America experienced a rapid decline in revolts in the early 1900s. Historical narratives and an analysis of a comprehensive new dataset show that the decrease stemmed in large part from the expansion and professionalization of the region’s militaries, which were driven by an export boom and the threat of interstate conflict. 

Christopher Darnton responds to Rachel Metz's Winter 2022/23 article, "The Cult of the Persuasive: Why U.S. Security Assistance Fails."

Ownership of reforms by citizens is often presented as important for success. This paper explores media engagement and support for economic reforms in the Gulf Cooperation Council (GCC) countries using text analysis techniques on publicly available sources. Results show that while reform efforts have intensified in recent years in the GCC, these efforts tend to focus on stronger rather than weaker policy areas, potentially limiting the growth-enhancing effect of reforms. Social media analysis using Twitter shows that the population’s support for reforms has been declining. The analysis of traditional
news media points to more engagement by international than by local media. However, sentiment from international media is less positive about economic reforms in the GCC. Sentiment in international media and social media matters, as evidenced by its positive and strong correlation with FDI inflows into the GCC.

Mass killing such as cleansing and genocide is a common occurrence in war. Communities face the terrible choice of leaving their homes ahead of military action, or staying. Analysis of the previously restricted “Village Files,” a Zionist survey of Arab Palestinian communities conducted in the 1940s, finds that the key indicator of whether a community flees imminent violence is social cohesion.

Meghan Garrity details the history of mass expulsions since the centennial of the signing of the Lausanne Convention—a treaty codifying the compulsory “population exchange” between Greece and Turkey. An estimated 1.5 million people were forcibly expelled from their homes: over one million Greek Orthodox Christians from the Ottoman Empire and 500,000 Muslims from Greece.

Stephen Walt provides A realist POV on the war in Ukraine, competition with China, COVID, and more in the second part of an interview with Foreign Policy Editor-in-Chief Ravi Agrawal.

Charli Carpenter and Lise Howard write that a U.N. peacekeeping mission could help avert civil war in Afghanistan.

Nathaniel L. Moir writes of historical cases in which a U.S. tendency to over-rely on military capabilities and American economic strength proved unwise and how such power eventually proved to be irrelevant. In addition to the Vietnam War as an example, the rapid collapse of the Republic of China and its large military forces in late 1948 and 1949 offers some parallels with the collapse of the Afghan National Army and the Afghan Government, despite the United States investment of trillions of U.S. dollars.

Analysis of unique data on more than 19,000 reported deserters of the Revolutionary Armed Forces of Colombia (FARC) reveals that organizational decline undermines a group’s instruments to promote collective action—including selective incentives, ideological appeal, and coercion—and leads to desertion.
