高市为何想修改无核三原则？

Core Viewpoint - Japan's nuclear policy, based on the "Three Non-Nuclear Principles" of not possessing, not producing, and not allowing the introduction of nuclear weapons, is facing potential modifications, particularly regarding the "not allowing" aspect, which may align with U.S. military strategies [1][3][6]. Group 1: Current Discussions and Political Dynamics - The ruling Liberal Democratic Party (LDP) plans to hold a study session on November 20 to outline topics for revising security documents, with discussions potentially including the non-nuclear principles [3][14]. - High-ranking officials within the Japanese government have indicated that the modification of the "not allowing" principle could be a topic of discussion in upcoming security document revisions [4][6]. - Former Self-Defense Forces Chief Kono Katsutoshi has emphasized the necessity of discussing operational cooperation with the U.S., suggesting a shift in Japan's nuclear stance due to changing geopolitical threats [8]. Group 2: Historical Context and Policy Evolution - The "Three Non-Nuclear Principles" were first articulated in 1967 by then-Prime Minister Sato Eisaku, establishing a framework that has since been challenged by the realities of U.S. military deployments [9][10]. - The principle of "not allowing" has been interpreted flexibly, leading to what some describe as a "2.5 principles" approach, where exceptions may be considered in times of crisis [11][14]. - The U.S. has historically maintained a policy of ambiguity regarding its nuclear capabilities in Japan, complicating the interpretation of Japan's non-nuclear stance [10][12]. Group 3: Regional and International Implications - Modifying the non-nuclear principles could escalate tensions with neighboring countries like China and North Korea, which possess nuclear capabilities that threaten Japan [6][14]. - There are concerns among Southeast Asian nations regarding the potential shift in Japan's nuclear policy, which could alter regional security dynamics [14].
