Since nuclear weapons testing began on 16 July 1945, nearly 2,000 have taken place. In the early days of nuclear testing little consideration was given to its devastating effects on human life, let alone the dangers of nuclear fallout from atmospheric tests. Hindsight and history have shown us the terrifying and tragic effects of nuclear weapons testing, especially when controlled conditions go awry, and in light of the far more powerful and destructive nuclear weapons that exist today.
On 2 December 2009, the 64th session of the United Nations General Assembly declared 29 August the International Day against Nuclear Tests by unanimously adopting resolution 64/35. The resolution calls for increasing awareness and education “about the effects of nuclear weapon test explosions or any other nuclear explosions and the need for their cessation as one of the means of achieving the goal of a nuclear-weapon-free world.” The resolution was initiated by the Republic of Kazakhstan, together with a large number of sponsors and cosponsors with a view to commemorating the closure of the Semipalatinsk Nuclear Test site on 29 August 1991.
2010 marked the inaugural commemoration of the International Day against Nuclear Tests. In each subsequent year, the day has been observed by coordinating various activities throughout the world, such as symposia, conferences, exhibits, competitions, publications, lectures, media broadcasts and other initiatives.
Since its establishment, many bilateral and multilateral governmental level developments as well as broad movements in civil society have helped to advance the cause of banning nuclear tests.
Moreover, “convinced that nuclear disarmament and the total elimination of nuclear weapons are the only absolute guarantee against the use or threat of nuclear weapons,” the General Assembly designated 26 September as the “International Day for the Total Elimination of Nuclear Weapons”, which is devoted to furthering the objective of the total elimination of nuclear weapons, through the mobilization of international efforts. The International Day for the Total Elimination of Nuclear Weapons was observed for the first time in September 2014. The International Day against Nuclear Tests, together with other events and actions, has fostered a global environment that strongly advocates for a world free of nuclear weapons.
The international instrument to put an end to all forms of nuclear testing is the 1996 Comprehensive Nuclear-Test-Ban Treaty (CTBT). Unfortunately, this has yet to enter into force.
As the Secretary-General recognized in his disarmament agenda “Securing our Common Future” launched on 24 May 2018, the norm against testing is an example of a measure that serves both disarmament and non-proliferation objectives. By constraining the development of advanced new types of nuclear weapons, the CTBT puts a brake on the arms race. It also serves as a powerful normative barrier against potential States that might seek to develop, manufacture and subsequently acquire nuclear weapons in violation of their non-proliferation commitments.
Every effort needs to be made to ensure the entry into force of the CTBT and to preserve its place in the international architecture. In this regard, the Secretary-General appeals to all remaining States whose ratifications are required for the CTBT to enter into force to commit to sign the Treaty at an early date if they have not already done so, and to accelerate the completion of their ratification processes.
It is the hope of the UN that one day all nuclear weapons will be eliminated. Until then, there is a need to observe International Day against Nuclear Tests as the world works towards promoting peace and security.
