The obligation to eliminate nuclear weapons

None of the world’s current nuclear-armed states chose to participate in the negotiation of the TPNW or its adoption, and to date, none has adhered to the Treaty. The Treaty provides two pathways to their future adherence: one for so-called destroy-and-join states (‘Article 4(1) states’), and a second for so-called join-and-destroy-states (‘Article 4(2) states’).
