This article examines the progress of the humanitarian initiative to reframe the nuclear weapons discourse internationally. The initiative seeks to shift debate away from theories of strategic stability and towards a focus on the impact of nuclear weapons themselves. This effort has now gathered significant support at an international level, and its implications are increasingly recognized by both nuclear-armed and non-nuclear-armed States. The initiative has been underpinned by the deliberate logic of humanitarian disarmament. A treaty banning nuclear weapons, around which momentum is gathering, would be an achievable, legally coherent and logical next step developing from the initiative.

This article describes the genesis of the humanitarian initiative and the political context in which it has developed in the course of the joint cross-regional statements and the three international conferences on this issue in Norway, Mexico and Austria. It examines the key substantive conclusions that have emerged as a result of this debate and assesses their relevance for the global nuclear disarmament and non-proliferation regime. It concludes that these facts and findings warrant an urgent reassessment of the so-called security value of nuclear weapons and a nuclear deterrence-based notion of stability and security.
