Perspectives on the Implementation of the 2017 Nuclear Weapons Ban Treaty

The adoption of The Treaty on the Prohibition of Nuclear Weapons (TPNW) by the UN General Assembly in July 2017 is a real success for the international community in the fight against armaments and the danger of an apocalyptic war. Despite the scepticism of many, the treaty entered into force in January 2021, with its 50th ratification. Although this story seems to have come to a happy end, it is only now that the turmoil begins. No nuclear-weapon state has supported the adoption of the treaty and they refuse to recognize its legal power. The implementation of this treaty will be the hardest test for the UN. Nuclear states are the strongest and most decision-making, especially within the Security Council. In this context, the question arises whether the UN will succeed in finding an effective way to persuade nuclear states to give up these weapons or whether we will witness an international “putsch” of nuclear states.
