Summary

Shigeru Ishiba, a former Minister of Defense, holds a robust and evolving position on Japanese defense, emphasizing the need to ensure the credibility of the US nuclear umbrella and strengthen Japan's self-defense capabilities. He has acknowledged the humanitarian miseries of nuclear weapons but argues that, from a security viewpoint based on balancing power, they are necessary for the time being, especially given threats like North Korea's program. A significant part of his stance involves critically scrutinizing the U.S. extended deterrence commitment and suggesting a need for regular, high-level political discussions regarding its nuances and Japan's role in a nuclear scenario, including the prior consultation mechanism.

His approach signals a departure from strict adherence to post-war norms, as evidenced by his past exploration of Japan maintaining the technical capability to build nuclear weapons, which he termed a 'potential nuclear deterrence'. Furthermore, he has proposed ambitious restructuring, such as the creation of an Asian NATO-like framework and exploring nuclear sharing modeled after NATO, alongside bolstering missile defense systems like the SM-3 Block 2A. Despite these hawkish explorations, his political reality, particularly as a minority government leader, has forced him to temper rhetoric and focus on enhancing existing alliances and building multilateral cooperation.
