Former UN High Representative for Disarmament Affairs, Sergio Duarte, warns that the taboo against nuclear testing is at risk. That pressure to resume testing appears to be increasing, and the ongoing modernization of nuclear arsenals in several States could make their use justifiable and acceptable in a “limited” nuclear confrontation.duarte

“Once the taboo against testing is broken, the whole normative structure painstakingly built by the international community to curb the spread of nuclear weapons and advance the goal of nuclear disarmament will risk unraveling. The entry into force of the CTBT is a vital element to prevent such a dangerous development
and will also help to prevent an acceleration of the nuclear arms race and an escalation of regional and bilateral tensions.”

How to Ban Nuclear Tests, blog entry by UK Ambassador Leigh Turner

In the years between 1945 and 1996 the nuclear-weapons states have carried out about one nuclear test per week. That adds up to over 2000 in total. But since September 1996, only three countries have undertaken nuclear tests.  In this century, only North Korea has done so, with tests in 2006, 2009, 2013 and 2016 (twice).

What happened? – The Comprehensive Nuclear-Test-Ban Treaty (CTBT) was opened for signature. As well as discouraging testing, it also mandated the creation of the International Monitoring System (IMS) to provide a global monitoring capability to detect nuclear explosions.  The IMS can detect vibrations in the earth, sound in water, or radionuclide particulates and noble gases released by nuclear explosions.

Read the SIPRI article here.

On 24 September, “the longest-sought, hardest-fought prize in arms control history” marked its 20th birthday, but has yet to come of age.

Tariq Rauf, Programme Director of SIPRI’s Disarmament, Arms Control and Non-proliferation Programme, writes about the less-than-happy anniversary of the Comprehensive Nuclear-Test-Ban Treaty’s (CTBT) opening for signature. UN Secretary-General Ban Ki-moon recalled that this event is “not a celebration. It is a stark reminder of the work that remains.”

With the official ratification of the CTBT by Swaziland and Myanmar on 21 September, the number of States who have ratified the Treaty rose to 166, out of a total of 183 signatures. But near-universality is not enough for the CTBT to enter into force; for that the 44 States named in Annex 2 have to sign and ratify. Of these, 36 States have already signed and ratified, whereas 5 have not yet ratified: China, Egypt, Iran, Israel and the USA; and a further 3: India, North Korea and Pakistan have never signed.

Entry-into-force of the CTBT

Though the US Senate rejected ratification of the CTBT in October 1999, President Obama tabled Resolution 2310 (2016) at the UN Security Council on 23 September of this year. The resolution called upon all States to refrain from conducting any nuclear-weapon test or any other nuclear explosion, urged all States, especially the 8 remaining Annex 2 States, to sign and/or ratify the Treaty “without further delay”, and recognised that “early entry into force of the Treaty will constitute an effective nuclear disarmament and non-proliferation measure that would contribute to the achievement of a world without nuclear weapons”. Particular praise was levelled at the Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO) and the “unprecedented reach” of its International Monitoring System (IMS).

Of the 15 members of the council, 14 voted in favour, with Egypt abstaining. This resolution, though non-legally binding, together with the Joint Statement on the CTBT made by the NPT nuclear-weapon States on 15 September demonstrate the that political will to bring the CTBT into force still exists after 20 years of campaigning, and constitute welcome steps towards this goal.

If the international community is serious about the CTBT, then then it must act. That political will must be felt. Those countries that have continued to block the entry into force of the Treaty need to hear from their friends and allies that the CTBT is and will continue to be a top priority in the efforts to prevent the spread of nuclear weapons and reduce the nuclear threat.

 The entry into force of the CTBT is not just the responsibility of any one group of states. The CTBT represents the culmination of a decades-long endeavour by the international community, both scientific and technical, but also diplomatic and political, to put an end to nuclear testing by anyone, anywhere, for all time. And the world is already reaping the benefits of the Treaty even though it has not yet entered into force.

– Dr Lassina Zerbo, Executive Secretary Comprehensive Nuclear-Test-Ban Treaty Organisation, April 2015

Recent tests by the Democratic People’s Republic of Korea, while unfortunate, demonstrate the enduring value of the CTBT verification platform offered by the IMS, and serve as a “true testament that multilateral verification is effective, reliable and necessary for moving toward a world free of nuclear weapons.” – Dr Zerbo

But the verification system, a $1 billion investiment, can be used for more than detecting nuclear tests. “The IMS is based on four complementary verification methodologies, utilizing the most modern technology available. Seismic, hydroacoustic and infrasound stations monitor the underground, the large oceans and the atmosphere respectively.” And as Tariq Rauf points out, these technologies have a wide variety of civilian and scientific uses; from picking up earthquakes and helping to issue tsunami warnings, to monitoring climate change, analysing meteor impacts, and tracking the migration of whales.

The CTBT’s 20th birthday is not a happy one, but it has not passed unnoticed or without progress. The UN Security Council resolution and Joint Statement by the NPT nuclear-weapon States bring us ever closer the entry into force, but as Tariq Rauf says, “The CTBT remains ‘unfinished business’ from the legacy of the Cold War. It is time that the business is completed of finally putting an end to all nuclear explosions in all environments for all time and to reap the civilian and scientific benefits for humanity of the IMS, which is the world’s most extensive international verification and monitoring system—by securing the entry-into-force of the CTBT without further delay.”

Let’s finish what we started.
