Since nuclear weapons testing began on 16 July 1945, over 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 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 signing 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.
On 2 December 2009, the 64th session of the United Nations General Assembly declared 29 August the International Day against Nuclear Tests through the unanimous adoption of its resolution 64/35. The Preamble of the resolution emphasizes that “every effort should be made to end nuclear tests in order to avert devastating and harmful effects on the lives and health of people” and that “the end of nuclear tests is one of the key means of achieving the goal of a nuclear-weapon-free world.”
The main mechanism for eradicating nuclear weapons testing is the Comprehensive Nuclear-Test-Ban Treaty (CTBT). It was adopted by the United Nations General Assembly on 10 September 1996. To date, 185 countries have signed the treaty and 170 have ratified it. For the Treaty to enter into Force, it must be ratified by those States with significant nuclear capabilities.
While the general consensus within the international community is that nuclear weapons tests pose life-threatening risks, there still exists to some degree a lingering suspicion of the possibility of clandestine nuclear weapons testing. There is also a concern that if nuclear weapons cannot be tested their reliability may be in jeopardy. However, over the years, advances in science and technology have exponentially boosted the capacity to monitor and verify compliance mechanisms and nuclear weapons proliferation detection. These activities and tracking tools have been initiated and developed by the Provisional Technical Secretariat of the CTBT Organization (CTBTO) Preparatory Commission. Despite the stalled entry-into-force, an increasingly robust public advocacy, including activities and events undertaken on the International Day against Nuclear Tests, is exerting pressure on the powers-that-be to move forward on the ratification of the treaty with a view towards the ultimate eradication of nuclear weapons testing.
The Preparatory Commission of the CTBTO and its 170 ratifying States vigorously continue to push for the Treaty’s entry into force. The CTBTO’s International Monitoring System, already encompassing nearly 90 per cent of States, provides confidence that no nuclear explosion will escape detection.
However, nothing can play as crucial a role in avoiding a nuclear war or nuclear terrorist threat as the total elimination of nuclear weapons. Bringing an irreversible end to nuclear explosions will prevent the further development of nuclear weapons.
Since the International Day against Nuclear Tests was first declared, there have been a number of significant developments, discussions and initiatives relevant to its goals and objectives as well as conferences convened to elaborate and advance these developments.
