How Can the TPNW Regime Be Sustained?

Experience in implementing both other WMD treaties and other humanitarian disarmament treaties suggests that the TPNW regime can be effective in building and sustaining a global norm against nuclear weapons, even if no nuclear-armed state joins the treaty. Success will depend on the development of an active and diverse practitioner community focused on the core humanitarian aims of the treaty, practical implementation of its positive obligations, integration and communication with the wider international community, and further strengthening of the global nuclear non-proliferation regime.
