The text of the TPNW was agreed during a relatively short negotiation period. It includes comprehensive prohibitions regarding participation in any nuclear weapon activities, including undertakings not to develop, test, produce, acquire, possess, stockpile, use or threaten to use nuclear weapons. The Treaty prohibits the deployment of nuclear weapons on national territory and requires states parties to prevent and suppress any prohibited activity by persons within or on their territory or under their jurisdiction or control.

The Treaty on the Prohibition of Nuclear Weapons 2017 marks an important development in nuclear arms control law, diplomacy and relations between states. Adopted by the UN General Assembly on July 7, 2017, it was supported by 122 nations, representing a potential disruptor to the nuclear status quo. It is the first treaty to ban nuclear weapons outright, taking a clear humanitarian approach to disarmament. Despite its success in coming to fruition, however, it is not celebrated by all nations. The permanent members of the UN Security Council neither participated in its negotiations, nor adopted the final text. No state with nuclear weapons endorses the Treaty and indeed they openly oppose its very existence.
