Koizumi's Call For Taboo-Free Discussion Triggers Outrage Among Survivors

Japanese Defense Minister Shinjiro Koizumi has sparked outrage among atomic bomb survivors and local leaders by calling for a debate on nuclear weapons without taboos. Koizumi’s remarks, made during an online program and later repeated during a visit to Belgium, have been interpreted as suggesting a potential review of Japan’s Three Non-Nuclear Principles. The principles, which prohibit the possession, production, and introduction of nuclear weapons into Japan, have been a cornerstone of the country’s defense policy since the 1960s. The government has stated that it remains committed to the principles, but speculation is growing about a potential revision. The controversy was first reported by The Asahi Shimbun.
