I Saw the Sign: Explaining Military Signals


Signaling one's resolve and capabilities should help countries avoid war by communicating the conditions for a negotiated bargain that can serve the same ends as war. However, the spiral model of conflict holds that communicating resolve and capability could cause your opponent to feel threatened and respond in kind, thus escalating tensions. How can preparation for conflict be a deterrent, yet also be a precursor to conflict? This disagreement begs the question of why countries sometimes signal prior to conflict but in other instances they do not. To fully understand a country's decision to signal or not signal prior to a conflict we must therefore understand the relationship between signaling and what a country hopes to 'win' in a dispute. This paper suggests that countries hoping to achieve a negotiated settlement will militarily mobilize in an informational manner designed to signal while those that hope to fight a conflict will militarily mobilize in a tactical manner designed to win. Analyzing signaling through military mobilization in 470 crises over the past century reveals variation in the military tools used, their role in signaling, and the consequent effect on what crises escalate to conflict.

An Empirical Approach to Defining Military Domains


Military capacity is considered central to national power, yet its measures remain aggregated and generalized. This paper aims to produce a better understanding of military capacity through a nuanced analysis of military technologies. The acumen of these technological bundles determine the military systems available to a given country and thus define military strategy, structure, and success. This research paper introduces the DoD's Militarily Critical Technologies List (MCTL) to shed light on the composition of technological bundles as well as empirically identifying military domains based on their technological portfolios. This new way of thinking about military technology through empirical validation will shed light on nations' system integration skills, the complementarity and substitutability of military technologies, and the role that alliances, trade ties, and domestic factor endowments play in shaping a military's technological portfolio.

After Deterrence: Explaining Conflict Short of War


Policymakers are increasingly concerned about conflict ``in the gray zone"--- the region between peace and war where, it is feared, challengers are able to alter the status quo without fear of triggering a larger military confrontation.  Paradigmatic examples include the Russian annexation of Crimea and incursion into Eastern Ukraine and China's island building campaign in the South China Sea. Here, we define gray zone conflict in a manner that emphasizes theoretical consistency and highlights novel features and implications of its causes. While gray zone conflicts are often perceived as deterrence failures, they are better understood as responses to deterrence success. A key puzzle involves understanding why capable countries choose to fight in a limited fashion. To the degree that gray zone conflict results from prior deterrence successes, raising the cost of limited war could yield peace. Alternatively, the decision to fight in the gray zone could reflect an optimal low-cost war fighting strategy, in which case doubling down on deterrence risks escalation and broader war.

Cruisin' to Victory: The Effects of US Cruise Missile Strikes Since the Gulf War


Un-piloted weapons have become an increasingly common tool in US military strategy, yet most relevant scholarship has focused on drones. This paper complements that research by providing the first comprehensive dataset of the entire universe of  US cruise missile strikes from 1991-2017. This fine grained data allows scholars to examine the important of the various platforms used to launch cruise missiles, the geographic location and type of specific targets, and when cruise missiles are utilized during military operations. This article introduces the dataset of all US cruise missile incidents from 1991-2017, describes the variables of interest, and suggests important political questions that can be analyzed through the use of this data.
