Evidence from the Historical Record
This chapter provides a series of quantitative, large-n analyses of nuclear reversal that test the core propositions and hypotheses derived in Chapter 2. It expands on existing work to systematically examine all states that engaged in nuclear weapons activity. It overviews the data on rewards (political, military, or economic) and punishments (economic or military) for analysis. It presents several statistical tests of the six hypotheses derived in Chapter 2. Using a time-series panel study that incorporates a variety of model specifications examining the impact of inducements on nuclear reversal, it finds significant support for the theoretical framework introduced earlier. Further, it finds support for the probabilistic conditions that examines special circumstances of leadership change and nuclear reversal among allies and adversaries. Appendix 3.1 presents a battery of robustness checks to provide additional support for the findings.
