Join IPPNW’s 24th World Congress in Nagasaki, Japan. This historic occasion marking the 80th anniversary of the atomic bombings of Hiroshima and Nagasaki offers an unparalleled opportunity to reflect on the devastating consequences of nuclear weapons and to recommit to global efforts toward disarmament. The main Congress will be 2-4 October, 2025 with a Student Congress on 1 October.

Earlier this month, IPPNW, ICAN, and Pugwash hosted a webinar, “Autonomous Armageddon: Nuclear Weapons and AI“, to explore the alarming dangers posed by the integration of artificial intelligence (AI) into nuclear weapons systems.

The expert panel discussed the general and specific risks AI presents to nuclear command and control systems, the catastrophic humanitarian and environmental consequences of nuclear war, and ongoing initiatives to mitigate these threats.
