<P> A third draft was presented on 3 July 2017 . A last obstacle for agreement was the condition of the withdrawal clause, meaning that a state party "in exercising its national sovereignty, (...) decides that extraordinary events related to the subject matter of the Treaty have jeopardized the supreme interests of its country". The majority perspective was that this condition is subjective, and no security interests can justify genocide, nor can mass destruction contribute to security . However, as also a neutral withdrawal clause not giving reasons was not accepted by the minority, the respective Article 17 was accepted as a compromise . Safeguards against arbitrary use are the withdrawal period of twelve months and the prohibition of withdrawal during an armed conflict . </P> <P> The vote on the final draft took place on 7 July 2017, with 122 countries in favour, 1 opposed (Netherlands), and 1 abstention (Singapore). </P> <P> Among the countries voting for the treaty's adoption were South Africa and Kazakhstan, both of which formerly possessed nuclear weapons and gave them up voluntarily . Iran and Saudi Arabia also voted in favour of the agreement . There are indications that Saudi Arabia has financially contributed to Pakistan's atomic bomb projects and in return has the option to buy a small nuclear arsenal, an option that would be realized in the event that Iran obtains nuclear warheads . The aim of the Iran nuclear deal from 2015 was to prevent this case . </P> <P> According to the International Campaign to Abolish Nuclear Weapons (ICAN), a coalition of non-governmental organizations, leading proponents of a nuclear - weapon - ban treaty include Ireland, Austria, Brazil, Indonesia, Mexico, Nigeria, South Africa and Thailand . All 54 nations of Africa (all but one of which have either signed or ratified the 1996 Treaty of Pelindaba establishing a nuclear - weapon - free - zone in the continent) and all 33 nations of Latin America and the Caribbean (already in a nuclear - weapon - free - zone under the 1967 Treaty of Tlatelolco) had subscribed to common regional positions supporting a ban treaty . The 10 nations of the Association of Southeast Asian Nations (ASEAN), which concluded the Southeast Asian Nuclear - Weapon - Free Zone Treaty, participated in the negotiations, but Singapore abstained from the vote . Many Pacific island nations are also supportive . </P>

Un member states will sign the treaty on the prohibition of nuclear weapons
