It’s time to challenge conventional wisdom and chart a new path for global security free from the existential threat of nuclear weapons.


Drawing on proven practices for large-scale systems change, Horizon 2045 is advancing a new frontier of thinking by designing, testing, and building momentum for an alternative global security architecture. Based on technical, social, and political cooperation, this “whole of society” initiative engages nontraditional actors—designers, ethicists, philosophers, cultural influencers, and more—to work in partnership with security experts to imagine and ultimately achieve a world without nuclear weapons. While it may take decades, our audacious goal is to rid the world of nuclear weapons by 2045, the 100th anniversary of the first atomic bomb.
