The treaty on the non proliferation of nuclear weapons (NPT) : a treaty initially time limited

Right after the end of the Second World War, all countries realized what was at stake regarding nuclear proliferation. Thus was created the International Atomic Energy Agency (IAEA) in 1957. Discussions were also soon engaged to lead to the partial nuclear test ban treaty (PTBT) in 1963, short after the Cuba missile crisis, and finally the Treaty on the non-proliferation of nuclear weapons (NPT).

The NPT was opened for signature on 1st July 1968. It entered into force on 5 March 1970, the United States of America, the United Kingdom of Great Britain and Northern Ireland and Russia being the States depositaries of the treaty. France announced its accession to the NPT within the framework of a “comprehensive plan for arms control and disarmament” presented by President Mitterrand to the United Nations on 3 June 1991. France joined the Treaty on 2 August 1992 and yet had been complying with its provisions since 1968.

The NPT was specific among treaties for it was agreed for an initial period of 25 years after its entry into force, that is to say till 1995, initially.

According to the Treaty, States parties gathered every 5 years to discuss the treaty implementation and more specifically, from 17 April till 12 May 1995, on the future of the Treaty itself: disappearance, a new time limited prorogation or indefinite prorogation.
By a decision made on 11 May 1995, States parties to the NPR made the choice of the indefinite prorogation of the Treaty:

Decision 3
The Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons, Having convened in New York from 17 April to 12 May 1995, in accordance with article VIII, paragraph 3, and article X, paragraph 2, of the Treaty on the Non-Proliferation of Nuclear Weapons,
Decides that, as a majority exists among States party to the Treaty for its indefinite extension, in accordance with article X, paragraph 2, the Treaty shall continue in force indefinitely.

In the global framework that supported this decision, establishing a Comprehensive nuclear Test Ban Treaty was agreed and that led to the CTBT opening for signature in 1996, along with the creation of the related organization, the CTBTO in Vienna.
