Red means the country is a member of the 2017 UN Treaty on the Prohibition of Nuclear Weapons, so making, having, using, threatening to use or hosting nuclear weapons is banned (UN treaty records, November 2026). Amber means it signed but has not ratified, so it is not bound yet. Green means it has not joined this treaty. Most green countries are still barred from getting nuclear weapons by the older Non-Proliferation Treaty.
- UN Treaty Collection, 8 Nov 2026: Status of Treaty XXVI-9 (Signatories: 96, Parties: 75), participant table with signature and ratification/accession dates
- UN Office for Disarmament Affairs: Treaty text (art. 1 prohibitions, art. 15 entry into force) and status
- ICAN signature and ratification status: Cross-check of parties and signatories (its older status page still showed 74/95 on 8 Nov 2026, before Tonga's entry into force and Gabon's signature; UNTC, the depositary, governs)
Each country in the lists names the source for its rule; countries not listed had no qualifying national law in these sources. Laws as of November 2026. We map the law on the books, not how well it is enforced.
United States: Not in the 2017 nuclear ban treaty. The US has not signed the Treaty on the Prohibition of Nuclear Weapons. Treaties are federal, so states don't differ. Law: Not a signatory or party to the Treaty on the Prohibition of Nuclear Weapons (UNTC XXVI-9). The US is one of the five nuclear-weapon states recognised by the 1968 NPT.
US sources: UN Treaty Collection, status of the Treaty on the Prohibition of Nuclear Weapons (XXVI-9), as at 8 Nov 2026: United States not listed as signatory or party; Treaty on the Non-Proliferation of Nuclear Weapons (1968), art. IX(3): a nuclear-weapon state is one that manufactured and exploded a nuclear device before 1 Jan 1967
