Skc11nes Rational deterrence theory posits that deterrence is more likely to be successful when a state credibly communicates to its adversary that it has both the capability and intent to retaliate against threats. Yet, second-generation nuclear states, which often exist in severe security environments, have largely adopted postures ofnuclear ambiguity where they do not acknowledge their nuclear weapons capabilities or the circumstances under which they would use them. To date, research has been insufficiently comparative. While some existing research offers explanations for the ambiguous nuclear postures ofindividual countries, it does not permit us to draw inferences across cases and assess relative explanatory power. Through comparison, both within and across cases, this project develops a more general explanation ofwhy nuclear states choose ambiguity over a visible deterrence posture. To this end, this project analyzes the nuclear postures ofthree countries: Israel, India, and Pakistan. Using process tracing and the congruence procedure methodology, I v assess the relative validity ofexisting explanations for each case and then compare these findings across the three cases. This research suggests that regional security environments, characterized by disparities in power, create strong incentives for states to acquire nuclear weapons capabilities for deterrence as well as to retain an ambiguous posture. In particular, an ambiguous posture enables regional states to avoid the costs and dangers ofcompetitive nuclear development vis-a.-vis their adversaries. The three cases also suggest that patron state pressures for non-proliferation, which combine threats and incentives, are another important constraint on the nuclear posture ofsecond-generation nuclear states. Other variables~-such as the international non-proliferation regime, domestic political interests, and the personal moral reservations ofsome state leaders-play some role to varying degrees in individual cases. However, these effects are limited both within the broad history ofindividual cases as well as in cross-case comparison ofthe three states. Understanding these constraints is helpful for evaluating the efficacy ofpolicy tools designed to prevent the spread ofnuclear weapons as well as how to manage crises and conflicts between regional nuclear-armed states.

SkaInes. Not only did Lars spend substantial time reading and editing, he did so with a straightforward and practical manner that kept my considerable tendency towards panic in check. With patience and professionalism, he guided me through this process, and his skills at collaboration and thoughtful attention have made all the difference. Dr. Jane K. Cramer deserves more gratitude than I have space to write. There are a select few individuals in one's lifetime that can influence professional and personal decisions simultaneously. I am grateful that Jane stands with a handful of few in my life that have contributed so substantially. Not only does she possess a deep and substantive knowledge in the field ofsecurity studies, but has also at every tum encouraged me to march forward with my life decisions. I am amazingly privileged to have had her input in both areas. And a most sincere thank to Dr. Shaul Cohen, for years ofpatience and willingness to see the end ofthis project through, even as I took a hiatus for law school. I am grateful for your candidness and considerable concern for students caught in the throes of academia. Thank you also to Dr. Ron Mitchell, who tells it likes he sees it, and always provide comments within a two-week period regardless ofwhatever else may be going on. His attention to structure and knowledge ofthe process has successfully guided many students. viii I would also like to express my gratitude to Judge Michael Mosman, the learned trial judge who understands that sometimes a change is better than a rest. Thank you for allowing me to make some changes that facilitated the end ofthe project. And to my large, opinionated, talented, beautiful, and wonderful family-Dad, Morn, Danielle, Ellen, Tracy, Marianne, Luke, Lisa, and Mariah-thank you. You have had many years ofhearing about how I am still working on my dissertation, and have always given steadfast encouragement and support. My friends have similarly suffered for my decisions, and I appreciated your patience in my absence, and the rather extensive editing provided by Michelle. Any errors or omissions, ofcourse, are mine alone. And Jason, thank you for always supporting my goals and decisions. I am fortunate to have such a partner in life. Thank you. IX To Jason. You know.

Yet, second-generation nuclear states, despite being regionally situated in severe security environments marked by a series ofwars over the last half century, have not openly utilized their nuclear capability in a way consistent with deterrence theory. Instead, undeclared nuclear states have pursued policies ofopacity in which they largely deny the possession ofnuclear weapons and refrain from publicly issuing nuclear declarations or threats. Why do second-generation nuclear states pursue policies ofnuclear opacity, which may result in making deterrence less effective than declaring capabilities and intentions?
