Global Nobel Laureate Summit on AI and Nuclear War

IPPNW was part of the coalition initiating the Global Nobel Laureate Summit on Artificial Intelligence and Nuclear War at the Vatican in July of 2026 in Castel Gandolfo.

IPPNW attended the conference to advocate for the abolition of nuclear weapons through the Treaty on the Prohibition of Nuclear Weapons, and a permanent firewall on AI and related technologies and Nuclear Weapons systems.

The Rome Declaration adopted by participants of the conference called for “urgent, sustained and good-faith negotiations
leading, within an agreed and time-bound framework, to the verifiable and irreversible elimination of nuclear weapons.”

Nuclear Armed Nations

Nuclear armed nations

9 nuclear armed states – US, UK, Russia, China, France, India, Pakistan, Israel, North Korea- possess approximately 12,000 nuclear weapons.  These arsenals, possessed by only a few countries, have the power to destroy the world as we know it many times over. Only 3% of their nuclear power could kill up to every 3rd person on earth.

Nuclear Abolition

IPPNW Global Network
