On 7 July 2017 a UN Conference, convened in New York by the General Assembly, adopted a Treaty on the Prohibition of Nuclear Weapons, providing for the first total ban on these weapons intended to be global in scale. The Treaty was opened for signature on 20 September 2017. The process and its outcome, were, however, firmly opposed by nuclear-weapon States and by NATO countries, including Italy: they refused to take part in the effort, fearing that it could definitively undermine the stability of the non-proliferation architecture built upon the 1967 Non-Proliferation Treaty. In reality, the Treaty is consistent with the ultimate purpose of the NPT regime, and the obligations assumed by States under the NPT remain untouched. Its main deficiencies relate to its verification apparatus, and it would be advisable to remedy them through future negotiations. Whether this instrument will enter into force is not clear, although it has the potential to acquire, and surpass, the fifty ratifications necessary. However, the absence of support from nuclear-weapon States risks rendering it irrelevant. Nevertheless, it seems plausible that broad support for this new regime, from non-nuclear-weapons States, as well as from civil society, could contribute to exerting pressure towards the adoption of concrete steps in the nuclear disarmament agenda.
