Theory of change

Abstract

This report by Horizon 2045, a collaborative effort of three organizations, is an invitation to think with it. It presents concepts that drive its theory of change to eliminate nuclear weapons, discusses stories that perpetuate nuclear deterrence, and underscores the vulnerabilities of the current nuclear system. It argues that a new approach to nuclear risk reduction, nuclear ideology, and a reimagined global security system independent of nuclear weapons are necessary to achieve a nuclear-free world. The report suggests avenues for change to disrupt the present system, including broadening the community, tying nuclear issues to other global concerns, driving change in the nuclear base layer, challenging the system, and building cooperation models. It emphasizes the need for a collective effort towards a future without nuclear threats and the promise of a brighter post-nuclear existence. – AI-generated abstract.
