Memo to UNGA on Sept 26th High Level Meeting on Nuclear Disarmament

E-mail Print PDF



Dear Delegate,

September 26th is the International Day for the Total Elimination of Nuclear Weapons. On that day a High Level Meeting on Nuclear Disarmament will take place in UNHQ-NY, at which Governments should be represented at the very highest level possible – preferably at Presidential, Prime Ministerial or other Ministerial level. 

I am writing to urge that your country be represented at the highest possible level at that meeting on this matter of truly existential importance, as urged by the UNSG himself in his statement about Sept26th (text below, after this memo) and to use the occasion to announce or support nuclear-risk-reduction and disarmament measures.

The real risk of widespread use of nuclear weapons, an event that would likely end what we call civilization, is as high right now as it has been since the Cold War. 

In January 2018 a committee of Nobel laureates and nuclear weapons experts re-set the Doomsday Clock hands to 2 minutes to figurative 'midnight', which is as close as it has ever been, indicating the extremely high existential threat to humanity from nuclear weapons and climate change.

Since January 2018, nuclear risk factors have worsened, the latest increment being the demise of the INF Treaty, the likely demise of New START,  and the likelihood of a subsequent unrestrained arms race.

Back in 1983, at half past midnight Moscow time on Sep 26, the world came close to ending, as Soviet surveillance satellites mistook the reflections of sunlight off vertical high clouds directly over North Dakota for US ICBM launches. Fortunately the officer on watch at the time, Colonel Stan Petrov, thought there was 'a mistake somewhere' and declined to take actions that would likely have resulted in the launch of over 10,000 nuclear warheads, due to the fact that the Soviet Union and USA had launch-on-warning policies. Colonel Petrovs actions are re-enacted in the movie 'The Man Who Saved the World'which highlights that the USA and Russia have the same risky policies today that could lead to an inadvertent nuclear war. 

The movie has been shown a number of times at the UN. Colonel Petrov himself (as recorded in the movie) has visited the UN.

Exactly 30 years after Sept 26 1983, in 2013, the UN General Assembly adopted a resolution making Sept 26th the International Day for the Total Elimination of Nuclear Weapons 26 September and establishing a high – level meeting at the level of Prime Ministers, Foreign and Defense Ministers or Ambassadorial level on that day. 

NGOs also participate prominently in this meeting, as they do in a number of other UN disarmament meetings. The event will be live-streamed on http://webtv.un.org/

It is this meeting we urge your governments to prioritise.


It is above all the ACCIDENTAL outbreak of nuclear war via precisely such miscalculation, mistake, malfunction, or malware, (as it was on Sept26th 1983) that remains the most probable route to a potentially civilization-ending catastrophe. 

Efforts on nuclear risk reduction are of key importance. These worthy efforts need to be stepped up and given a much higher profile. Risk reduction measures include no-first-use commitments, lowering of operational readiness of nuclear weapon systems and increased decision-making times, better or resumed military to military communications, and implementation of a repeated commitment to establish a joint US-Russia nuclear risk reduction/data exchange centre in Moscow.

Serious consideration should be given to a First Committee resolution reaffirming that a nuclear war can never be won and must never be fought, and concluding that all options to initiate nuclear warfare should be unequivocally renounced.  It could also endorse specific measures such as de-alerting, No-First-Use, and improved or resumed military to military communication.

UN Statement on International Day for the Total Elimination of Nuclear Weapons


Achieving global nuclear disarmament is one of the oldest goals of the United Nations. It was the subject of the General Assembly’s first resolution in 1946, which established the Atomic Energy Commission, which was dissolved in 1952, with a mandate to make specific proposals for the control of nuclear energy and the elimination of atomic weapons and all other major weapons adaptable to mass destruction. The United Nations has been at the forefront of many major diplomatic efforts to advance nuclear disarmament since. In 1959, the General Assembly endorsed the objective of general and complete disarmament. In 1978, the first Special Session of the General Assembly Devoted to Disarmament further recognized that nuclear disarmament should be the priority objective in the field of disarmament. Every United Nations Secretary-General has actively promoted this goal.

Yet, today nearly 14,000 nuclear weapons remain. Countries possessing such weapons have well-funded, long-term plans to modernize their nuclear arsenals. More than half of the world’s population still lives in countries that either have such weapons or are members of nuclear alliances. While the number of deployed nuclear weapons has appreciably declined since the height of the Cold War, not one nuclear weapon has been physically destroyed pursuant to a treaty. In addition, no nuclear disarmament negotiations are currently underway. 

Meanwhile, the doctrine of nuclear deterrence persists as an element in the security policies of all possessor states and many of their allies. The international arms-control framework that contributed to international security since the Cold War, acted as a brake on the use of nuclear weapons and advanced nuclear disarmament, has come under increasing strain. Most recently, on 2 August 2019, the United States’ withdrawal spelled the end of the Intermediate-Range Nuclear Forces Treaty, through with the United States and the Russian Federation had previously committed to eliminating an entire class of nuclear missiles.

Frustration has been growing amongst Member States regarding what is perceived as the slow pace of nuclear disarmament. This frustration has been put into sharper focus with growing concerns about the catastrophic humanitarian consequences of the use of even a single nuclear weapon, let alone a regional or global nuclear war.

The General Assembly commemorates 26 September as the International Day for the Total Elimination of Nuclear Weapons. This Day provides an occasion for the world community to reaffirm its commitment to global nuclear disarmament as a priority. It provides an opportunity to educate the public - and their leaders - about the real benefits of eliminating such weapons, and the social and economic costs of perpetuating them. Commemorating this Day at the United Nations is especially important, given its universal membership and its long experience in grappling with nuclear disarmament issues. It is the right place to address one of humanity’s greatest challenges; achieving the peace and security of a world without nuclear weapons.

In accordance with General Assembly resolution 68/32 and subsequent resolutions, the purpose of the International Day is to further the objective of the total elimination of nuclear weapons through enhancing public awareness and education about the threat posed to humanity by nuclear weapons and the necessity for their total elimination. In so doing, it is hoped that these activities will help to mobilize new international efforts towards achieving the common goal of a of a nuclear-weapon-free world.
