Abstract:
Conflict between returning refugees and nonmigrant populations is a pervasive yet frequently overlooked security issue in post-conflict societies. Although scholars have demonstrated how out-migration can regionalize, prolong, and intensify civil war, the security consequences of return migration are undertheorized. An analysis of refugee return to Burundi after the country's 1993–2005 civil war corroborates a new theory of return migration and conflict: return migration creates new identity divisions based on whether and where individuals were displaced during wartime. These cleavages become new sources of conflict in the countries of origin when local institutions, such as land codes, citizenship regimes, or language laws, yield differential outcomes for individuals based on where they lived during the war. Ethnographic evidence gathered in Burundi and Tanzania from 2014 to 2016 shows how the return of refugees created violent rivalries between returnees and nonmigrants. Consequently, when Burundi faced a national-level political crisis in 2015, prior experiences of return shaped both the character and timing of out-migration from Burundi. Illuminating the role of reverse population movements in shaping future conflict extends theories of political violence and demonstrates why breaking the cycle of return and repeat displacement is essential to the prevention of conflict.

Abstract:
Liberals claim that globalization has led to fragmentation and decentralized networks of power relations. This does not explain how states increasingly “weaponize interdependence” by leveraging global networks of informational and financial exchange for strategic advantage. The theoretical literature on network topography shows how standard models predict that many networks grow asymmetrically so that some nodes are far more connected than others. This model nicely describes several key global economic networks, centering on the United States and a few other states. Highly asymmetric networks allow states with (1) effective jurisdiction over the central economic nodes and (2) appropriate domestic institutions and norms to weaponize these structural advantages for coercive ends. In particular, two mechanisms can be identified. First, states can employ the “panopticon effect” to gather strategically valuable information. Second, they can employ the “chokepoint effect” to deny network access to adversaries. Tests of the plausibility of these arguments across two extended case studies that provide variation both in the extent of U.S. jurisdiction and in the presence of domestic institutions—the SWIFT financial messaging system and the internet—confirm the framework's expectations. A better understanding of the policy implications of the use and potential overuse of these tools, as well as the response strategies of targeted states, will recast scholarly debates on the relationship between economic globalization and state coercion.

3. The End of War: How a Robust Marketplace and Liberal Hegemony Are Leading to Perpetual World Peace

Abstract:
Permanent world peace is beginning to emerge. States with developed market-oriented economies have foremost interests in the principle of self-determination of all states as the foundation for a robust global marketplace. War among these states, even making preparations for war, is not possible, because they are in a natural alliance to preserve and protect the global order. Among other states, weaker powers, fearing those that are stronger, tend to bandwagon with the relatively benign market-oriented powers. The result is a powerful liberal global hierarchy that is unwittingly, but systematically, buttressing states' embrace of market norms and values, moving the world toward perpetual peace. Analysis of voting preferences of members of the United Nations General Assembly from 1946 to 2010 corroborates the influence of the liberal global hierarchy: states with weak internal markets tend to disagree with the foreign policy preferences of the largest market power (i.e., the United States), but more so if they have stronger rather than weaker military and economic capabilities. Market-oriented states, in contrast, align with the market leader regardless of their capabilities. Barring some dark force that brings about the collapse of the global economy (such as climate change), the world is now in the endgame of a five-century-long trajectory toward permanent peace and prosperity.

4. Barriers to Entry: Who Builds Fortified Boundaries and Why?

Abstract:
Fortified boundaries are asymmetrical, physical barriers placed along borders. These boundaries are more formidable in structure than conventional boundary lines, but less robust than militarized boundaries. Their goal is to impose costs on infiltrators and in so doing deter or impede infiltration. A novel dataset of all such boundaries worldwide shows that states are constructing these barriers at an accelerating rate. More than half of barrier builders are Muslim-majority states, and so are the vast majority of targets. A multivariate analysis demonstrates that, contrary to conventional wisdom, states that construct such barriers do not tend to suffer disproportionately from terrorism, nor are they apt to be involved in a significant number of territorial disputes. Instead, differences in state wealth and migration rates are the best predictors of barrier construction. Qualitative case studies suggest that the most effective fortified boundaries are found where the initiating state controls the territory beyond a boundary that blocks the only access route into the state.
