The concluding chapter summarizes the book’s findings and examines its implications for both theorists and practitioners of international relations and nuclear security. In specific, it begins by providing a brief summary of the main argument, empirical results, and insights into current proliferation challenges. It next identifies four implications of this study for further consideration: rewards for tough proliferators, nuclear latency, multilateral bargaining, and credibility. It focuses on developments regarding current counterproliferation policy and how best to engage potential nuclear proliferators in the future. The chapter concludes with a summary of the recommendations for policymakers engaging in broader international efforts at nuclear reversal. Given the threat that future nuclear proliferators can pose to international security, there is no better time to focus our attention on the politics of nuclear reversal.
