The possession of nuclear weapons confers many benefits on a state. The path to proliferation, however, is often violent. When a state initiates a nuclear weapons program, it signals its intent to fundamentally alter its bargaining environment. States that once had an advantage will now be disadvantaged. This change in the environment is not instantaneous, but evolves slowly over time. This gives states both opportunities and incentives to resolve underlying grievances, by force if necessary, before a nuclear weapons program is completed. Our cross-national analyses of nuclear weapons program and the onset of militarized conflict confirm this expectation. In particular, the closer a state gets to acquiring nuclear weapons, the greater the risk it will be attacked (especially over territorial issues). Once nuclear weapons are acquired, however, the risk of being attacked dramatically drops, though not below the risk of attack for non-proliferators.Conventional wisdom holds that the possession of nuclear weapons offers states security from a number of international threats. In particular, the possession of nuclear weapons insulates a state from challenges to its most salient concerns (such as territorial integrity). While ultimately beneficial to proliferators, the path to nuclear status is generally neither instantaneous nor undetectable. As such, it behooves states that wish to challenge proliferators to realize their political goals sooner rather than later. Proliferators, on the other hand, have an incentive to delay the resolution of the contentious issue until the deployment of their nuclear weapons.In this article, we use this set of interacting incentives as a point of departure in delineating a theory of the relationship between the nuclear proliferation process and the frequency with which proliferators are targeted in conventional militarized conflicts. Though much previous scholarship has been devoted to this question, we believe that extant views have focused too narrowly on one subset of that relationship: the preemptive employment of conventional capabilities by status quo powers in order to physically disable or destroy proliferators' nascent nuclear programs. In developing a broader treatment of the strategic interaction between states, we posit that the various stages of deterrent nuclear proliferation are best conceived of as sequential steps in a bargaining process over preexisting disputes that were instrumental in spurring proliferators to consider nuclear options. As such, we contend that the primary rationale for status quo states' conventional targeting of proliferators should derive not from the desire to physically disrupt nuclear development (which is, at best, a difficult task), but from the desire to reach favorable conclusions to underlying disputes before the deployment of nuclear weapons drastically complicates the issue.The effect of nuclear proliferation on conventional targeting is tested quantitatively by looking at states in four different stages of the proliferation process: n...
