| Summary/Abstract |
By analyzing bilateral cooperation involving civilian nuclear technology from 2000 to 2015, this study finds potential proliferation uncertainty in recent technological nuclear cooperation. We use the dataset that divides technological nuclear cooperation into two categories - concrete and supportive, where concrete cooperation involves the more in-depth transfer of technology related to nuclear power and fuel cycle than supportive cooperation. We employ multinomial regression analysis to investigate what economic, political, military, and non-proliferation considerations enable more concrete nuclear cooperation. Our empirical results suggest that potential proliferation uncertainty exists in concrete cooperation. While concrete nuclear cooperation, in general, requires compliance with non-proliferation norms more strictly than supportive cooperation, examining military factors together with the compliance to the non-proliferation norms shows some concerns. Specifically, we find that suppliers of concrete nuclear cooperation have overlooked weak compliance with some non-proliferation norms when there exist common military interests. We also show that client countries with high military expenditure are more likely to engage in more concrete nuclear cooperation. Lastly, we find that supplier and client countries tend to complement their weak military alliance with more concrete nuclear cooperation. The findings underscore the responsibility of major suppliers and the international community for nuclear non-proliferation.

| Summary/Abstract |
What explains South Korean public opinion on nuclear weapons development? Despite the US security commitment, most South Koreans consistently support independent nuclear weapons development. To solve this puzzle, we investigate the mechanisms of security threat and security commitment under which individuals develop their opinion on nuclear proliferation. An original survey of 1,988 South Korean adults shows empirically supported correlates of South Korean public opinion on nuclear proliferation. Public support for proliferation is largely shaped by external security threats: nuclear threats from North Korea and China, but also the latent nuclear superiority of Japan. Public opposition to proliferation is fostered by the perceived credibility of the US security commitment, but not by its perceived effectiveness. The results provide insights into South Korean public opinion on nuclear proliferation and can inform the design of a nonproliferation policy tailored to South Korea.
