The Non-Proliferation Treaty opens for signature
The treaty was opened for signature simultaneously in London, Moscow and Washington. Its central definition confines the category of nuclear-weapon state to those that had tested before 1 January 1967, which both legitimises five arsenals and closes the door behind them — the asymmetry that non-nuclear parties have raised at every review conference since, pointing at the Article VI obligation to negotiate toward disarmament as the unfulfilled half of the bargain.
Historical — it happened, and the record is settled.

Treaty on the Non-Proliferation of Nuclear Weapons
Supports the opening-for-signature and entry-into-force dates, the three-pillar structure, the Article VI disarmament undertaking and the pre-1 January 1967 definition of a nuclear-weapon state. V55 verification basis: NOT consulted — www.un.org is blocked by the environment's egress proxy. The INFCIRC/140 designation is given because it is the standard IAEA circulation number for the treaty and is stated here as an identifier rather than as a document consulted; a curator should confirm it. No article is quoted verbatim in this pack.
