A new survey from the Centre for Strategic and International Studies indicates that strategic elites in both Japan and South Korea currently oppose developing nuclear weapons. The study reveals a strong preference for maintaining the status quo, relying on existing security alliances, particularly with the United States. However, the research highlights a significant potential for rapid change in public opinion. If either Japan or South Korea were to pursue nuclear armament, support for a similar move in the other nation would likely increase substantially. This suggests a delicate balance of deterrence and a potential domino effect regarding nuclear proliferation in the region. The report underscores the importance of maintaining stable security dynamics to prevent a shift in policy. The findings suggest regional stability hinges on continued adherence to non-proliferation commitments.
