On 7 July 2017, at the United Nations in New York, a Treaty on the Prohibition of Nuclear Weapons was voted by 122 Member States, one Member State, the Netherlands, voted against, and one Member State, Singapore, abstained. The nuclear-weapon States did not participate in the drafting of the Treaty.
Immediately after the positive vote, the delegations of the USA, the United Kingdom, and France issued a joint press statement saying that "This initiative clearly disregards the realities of the international security environment... This treaty offers no solution to the grave threat posed by North Korea's nuclear program, nor does it address other security challenges that made nuclear deterrence necessary."
Article I of the Treaty sets out its basic intention: to prohibit all activities involving nuclear weapons including to develop, test, produce, manufacture, acquire, possess or stockpile nuclear weapons and to use, threaten to use, transfer, station, install or deploy these weapons.
The Treaty will be open for signature and thus the start of the process of ratification at the start of the U.N. General Assembly on 20 September 2017. 50 ratifications are necessary for the Treaty to come into force. 21 September is the World Day for Peace, set by the U.N. General Assembly in 1981. The theme this year is "Together for Peace: Respect, Safety and Dignity for All".
