(2017) The Effect of US Troop Deployments on Human Rights, Journal of Conflict Resolution

Tags: Foreign Policy, Human Rights

US noninvasion troops deployed abroad often try to promote greater respect for human rights in the host country. The host country, having an incentive to retain the troop presence, may choose to comply with these requests. We argue that this effect will not be at play in states with high security salience for the United States (US) (for which the US may not be able to credibly threaten to remove the troops). In these cases, US deployments will provide the leader with security from both internal and external threats that is independent of the local population’s support for the leader. Host state leaders thus become less reliant on (and potentially less responsive to) their local populations, which in turn may lead to increased human rights violations. In this article, we use data on both US troop deployments abroad and on human rights violations to test these arguments from 1982 to 2005.

(2017) Militarism and Dual-Conflict Capacity, International Interactions

Tags: Conflict Processes & War

This research note examines how domestic institutions can moderate the relationship between domestic and interstate conflict involvement. Previous work has found that military dictatorships are more likely to become involved in either domestic or international conflicts, compared to party-based autocracies. We argue that the same institutional explanations for why military autocracies are more conflict-prone also make them less capable of successfully carrying out multiple conflicts at the same time. Analyzing interstate and domestic conflict involvement on a sample of dictatorships over the period 1947–2004, we show that military autocracies dealing with internal armed conflict are less likely than their nonmilitary counterparts to become involved in an international conflict.

(2017) Understanding the impact of air power, Conflict Management and Peace Science

Tags: Conflict Processes & War, Foreign Policy

With a lower risk of casualties and a high degree of precision, air power is an attractive foreign policy tool to powerful states that have increasingly relied upon it in recent years. This paper presents newly collected data on uses and effectiveness of air power in interstate wars from 1914 to 2003. The dataset provides more complete and comparable cases that can be useful in answering questions of not only the coercive effectiveness of air power, but also of the decision to use air power in conflict, of ethical concerns arising from the use of air power, and of the interaction of air power with other military and foreign policy tools. In addition to introducing the dataset and discussing trends in the data, a preliminary empirical application is provided, re-examining the relationship between strategy and air power effectiveness.

(2017) Does counterterrorism militarize foreign aid? Evidence from sub-Saharan Africa, Journal of Peace Research

Tags: Foreign Policy, Foreign Aid, Terrorism

This article studies whether the pursuit of counterterrorism militarizes foreign aid flows. It focuses on the case of US foreign aid to sub-Saharan African states, which recently have experienced an increase in the presence of al-Qaeda or its affiliate terrorist organizations. This article argues that as terrorist groups carry out attacks inside a state’s territory, aid towards that state will serve such counterterrorism goals. For one, the state’s executive branch will receive increased military aid to immediately fight al-Qaeda or affiliates. For the other, the United States also steps up aid for civil society and development, which could over time undermine al-Qaeda’s mobilization and recruitment efforts. In an empirical analysis that covers 46 African states from 1996 to 2011, our results largely corroborate the hypothesized patterns for attacks that occur on a country territory and in the neighborhood. We note, though, that the overall composition of aid shifts relative to the military when there are direct attacks, something that does not occur when attacks happen in the neighborhood only. Our article concludes that concerns about militarization of aid are warranted, but that actual manifestations are nuanced.

(2016) Domestic diversion and strategic behavior by minority groups, Conflict Management and Peace Science

Tags: Political Violence, Human Rights

Diversionary war theory states that leaders may initiate an international conflict in order to invoke internal cohesion and distract the public from domestic issues. Recent developments in diversionary literature suggest the possibility that leaders can alternately divert against domestic targets, such as minority groups. Empirical support for domestic diversion, though, has been mixed. In this paper we seek to reconcile this by further examining the different dynamics at play between actors who are faced with diversionary incentives. We suggest that a major reason why we do not observe many cases of domestic diversion is strategic behavior by minority groups. Much like states do, minority groups that are potential targets of repression engage in strategic conflict avoidance when they observe diversionary incentives to be present. We test our theory through a multivariate probit model that uses the state–minority group dyad as the unit of analysis.

(2015) Air Campaign Duration and the Interaction of Air and Ground Forces, International Interactions

Tags: Conflict Processes & War, Foreign Policy

This article explores the role that ground troops play in aerial campaigns. Specifically, it intends to explain how ground troops affect the duration of aerial bombing campaigns. It distinguishes between the effect of ground troops on the duration of aerial campaigns that are selective and on those that are more general and less discriminate (using newly coded data on aerial strategies). The effect of ground troops may vary depending on how air power is being used. Ground troops may increase the duration of aerial campaigns in cases in which selective strategies are used during the aerial bombing campaign. In these cases, states lose the possibility of quick, “clean” victories once ground troops are introduced. In the cases of the less-discriminate bombing campaigns, the effect of ground troops is the opposite: They shorten the duration of the bombing campaign, possibly through the increased effectiveness of a combined arms approach.

(2014) Major Powers and Militarized Conflict, Journal of Conflict Resolution

Tags: Conflict Processes & War

This article attempts to answer the question of why major powers engage in more active foreign policy behaviors than minor powers. It does so by comparing two explanations for the increased conflict propensity of major powers. The first explanation focuses on major powers’ observable capabilities, while the second stresses their different behavior. We incorporate both into an ultimatum model of conflict in which a state’s cost of conflict consists of both observable and behavioral components. Using data from the period from 1870 to 2001, we empirically illustrate the observable and behavioral differences between major and minor powers. We then utilize a decomposition model to assess the relative significance of the two explanations. The results suggest that most of the difference in conflict propensity between major and minor powers can be attributed to observable differences.

(2012) The Effect of US Troop Deployment on Host States’ Foreign Policy, Armed Forces & Society

Tags: Foreign Policy, Conflict Processes & War

Major powers often deploy troops abroad with the consent of host states. The stated aim of these deployments is often both to protect the host state and to foster stability in the region. Drawing from an extension of Palmer and Morgan’s two-good theory of foreign policy, the authors explore some of the (perhaps unintended) effects of troop deployments abroad on the foreign policies of the host states. In particular, the authors focus on the effects of US deployments. The authors argue that as the number of US troops deployed to a host state increases, we should expect the host state to reduce its own troop levels, be more likely to initiate militarized interstate disputes, and be less likely to be the target of interstate disputes. The authors test these hypotheses using data on US troop deployments abroad from 1950 to 2005 and discuss implications that their findings may have for US foreign policy.

(2011) Deterring Rebellion, Foreign Policy Analysis

Tags: Political Violence, Terrorism

Global terrorism and local rebellion are observed rather frequently; solutions appear to be rather sparse. A common strategy adopted by governments is to attempt to deter potential rebels from engaging in acts of violence, often by responding to attacks with violent reprisals directed at the populace from which the rebels are recruited. The logic supporting such a strategy follows from a theory of deterrence that we believe is underdeveloped. This theory focuses heavily on the credibility of the deterrent threat and on ensuring that the cost imposed by retaliation is high. This ignores the flip side of the deterrent threat—that is, the promise that if one does not misbehave (by engaging in acts of rebellion), one will not suffer retaliatory punishment. Policy designed to ensure that punishment is swift and severe (and perhaps disproportional) can undermine deterrence and actually encourage more potential rebels to become active. Using a game-theoretic model, we show that successful deterrence requires a strategy in which retaliation is proportionate and directed only at the guilty, as well as being certain. Moreover, potential rebels must believe that the innocent will have attractive opportunities outside of joining the insurgency as well as that the innocent will not be punished. We provide empirical illustrations of our thesis from participants in the Palestinian uprising, including several who have taken up arms against Israel.
