The recent additional sanctions against North Korea and Iran are unlikley to change these regimes' policies and could hav enegative effects if they hurt citizens rather than the powerful elite.
The 7 July deadline for a Joint Comprehensive Plan of Action regarding Iran's nuclear programme expired without a breakthrough but the parties agreed to an extension until the end of 10 July.
Some 50 heads of state and government are meeting today at the 2014 Nuclear Security Summit (NSS) in The Hague, the Netherlands, to highlight their commitment to strengthening nuclear security, and to agree on measures to prevent and combat nuclear terrorism. While many states hope that the Summit will increase nuclear security, the question remains as to whether the NSS process will be successful in securing all vulnerable weapon-usable nuclear materials.
North Korea launched a space launch vehicle on 7 February 2016 at around 09:00 local time, with the aim of placing a satellite into the Earth’s orbit.
The escalation of the current conflict in Syria gives greater impetus to efforts to determine the fate of Syria's weapon programmes and, in particular, its reported stocks of chemical weapons.
While the International Atomic Energy Agency has done an excellent job in verifying the nuclear material production activities in Iran’s uranium enrichment plants, it also appears to be willing to risk its technical credibility by insisting on visiting a military site called Parchin, near Tehran.
Following the November 2013 agreement in Geneva on initial measures to address Iran’s nuclear programme, negotiations begin in Vienna today on additional steps towards a comprehensive solution. In order for these negotiations to succeed, both sides will need to agree on pragmatic measures which assure the international community of the exclusively peaceful nature of the Iranian nuclear programme, and which lead to the removal of all United Nations Security Council sanctions against Iran.
The International Atomic Energy Agency (IAEA) and Iran failed again in two days of intensive talks held in Tehran this week to secure a deal to unblock the IAEA's long-stalled investigation into alleged atom bomb research in Iran. Agency inspectors were also refused access to visit a large military complex at Parchin that they have sought to visit for nearly a year. As tensions mount, it is worth considering why the Parchin visit has become such a hot-button issue in the dispute and whether it is really so important for addressing concerns about Iranian nuclear activities with possible military dimensions.
The latest round of negotiations in Geneva between Iran and the five permanent members of the United Nations Security Council plus Germany (the 'P5+1' states) once again failed to reach an agreement on interim steps toward resolving the long-running controversy over the future of Iran's nuclear programme. In the end, the talks faltered due to disputes over technical aspects of Iran's nuclear programme and the sequencing of sanctions relief, leaving the negotiators unable to conclude a much-anticipated deal.
The first case of Ebola outside of West Africa was confirmed in Dallas, Texas, which may be the tipping point for properly mobilizing the international community to act.
The Comprehensive Nuclear-Test-Ban Treaty (CTBT) prohibits all nuclear explosions anywhere as an effective measure of nuclear disarmament and non-proliferation but is yet to come into force. On 11 April SIPRI, in cooperation with the Swedish Ministry for Foreign Affairs (MFA) and the Swedish Institute of International Affairs (UI), held an event to discuss the CTBT and its wider applications.
On 6 January 2016, North Korea announced that it had successfully detonated a ‘hydrogen’ or thermonuclear device. Despite international doubt, we shouldn't underestimate North Korea's capabilities.
Today's launch by North Korea of an Unha-3 (or Taepodong-2) long-range rocket is already drawing strong negative reactions from many governments. However successful today's launch was, it does not mean that North Korea has, or is anywhere near having, the capability to launch a long-range ballistic missile strike, especially a nuclear-armed one.
A number of recent incidents have reinforced renewed concern regarding states' use of so-called riot control agents (RCAs)⎯particularly tear gases and pepper spray⎯against civilians. The legitimacy of RCAs as a means to maintain and restore public order is based on two assumptions: first, that they do no long-term harm to their targets, and second, that they are used responsibly and appropriately.
The 1972 Biological and Toxin Weapons Convention (BTWC) is one of the most widely ratified multilateral treaties concerning armed conflict since the Geneva Conventions. Its core principle has not been challenged: no country argues that the use of biological weapons is legitimate. Nevertheless, advances in science and technology are changing the very nature of ‘biological agents’ and the ways in which they can be produced and manipulated. As the BTWC approaches 40, is it still up to its primary task of preventing biological warfare?
Safeguards measures play a vital role in international efforts to monitor technologies related to reprocessing and enrichment of nuclear materials.
In the sovereignty disputes in the South China Sea, there is an often overlooked strategic interest pursued by China: the People’s Liberation Army’s (PLA) quest for a credible undersea nuclear deterrent.
Nuclear weapons kill immediately and kill over time. They cause devastation and environmental disaster. Twenty-five years ago a UN scientific commission warned that even a limited use of existing nuclear weapons could result in a nuclear winter over large areas over the earth. Recent findings conclude that such temporary climate change could cause the death of many millions of people. Massive use of existing nuclear arsenals would destroy all life on earth, a global suicide.
The lack of agreement at the 2015 Review Conference of the 1968 Treaty on the Non-Proliferation of Nuclear Weaponsis a big setback for nuclear disarmament.
Don't open the champagne just yet, but Russia and the United States are tantalizingly close to the finish line in their negotiations on a new nuclear arms reduction treaty to replace the 1991 Treaty on the Reduction and Limitation of Strategic Offensive Arms (START Treaty). Although the fast-track negotiations in Geneva were unexpectedly diverted into the diplomatic slow lane by last-minute wrangling over US missile defence plans, the two sides are widely expected to seal the deal and sign a START follow-on treaty within a matter of weeks.
Nuclear forensic analysis (nuclear forensics) has gained prominence as a tool to detect, prevent and deter acts of nuclear terrorism and illicit trafficking of nuclear materials. However, the potential applications of nuclear forensics go beyond nuclear security and demonstrate that cooperation can be achieved in and between a number of international security frameworks.
Perceptions of threats to security are both individual and shared. Currently, many share concerns about recent developments in Iran and North Korea, while many also see in the new approach of the United States a glimpse of hope. SIPRI—with its mandate to ‘contribute to an understanding of the conditions for peaceful solution of international conflicts’—aims through its annual SIPRI Yearbook to provide a basis on which threats can be assessed and to deliver the most relevant facts for the debate.
The so-called ‘Hiroshima Declaration’ adopted today by the G-7 Foreign Ministers is a major disappointment and a wasted opportunity for nuclear disarmament.
Today the Amendment to the Convention on the Physical Protection of Nuclear Material (CPPNM/A) enters into force after ratification by Nicaragua brings the total number of States Parties up to the required total.
After over 2,000 nuclear tests by 9 states, the world has still not agreed to a total ban on nuclear tests. Recent moves by Israel and the USA suggest we might be getting nearer.
North Korea's fifth nuclear test shows that the current policy of sanctions, name-calling and exhortations is not working.
On the 20th anniversary of the opening for signature of the Comprehensive Nuclear-Test-Ban Treaty, UN Secretary-General Ban Ki-moon said 'this is not a celebration. It is a stark reminder of the work that remains.'
On International Day for the Total Elimination of Nuclear Weapons, how close is the world to achieving nuclear disarmament?
A UN conference to negotiate a ‘legally binding instrument to prohibit nuclear weapons, leading towards their total elimination’ will begin next week. Tariq Rauf looks at who wants what.
SIPRI’s Ian Anthony reflects on the 1997 Helsinki Summit
The G20 Summit will be held in Hamburg on 7–8 July 2017. The UN Security Council and OPCW member states remain unable to agree Syrian Government responsibility for any of the continued instances of chemical warfare.
7 July 2017 was a momentous day for disarmament and arms control. On that day, 122 states approved the Treaty on the Prohibition of Nuclear Weapons, often called ‘the ban treaty’, at the United Nations in New York.
Lora Saalman provides the context for how threat perceptions are manifested in China's hypersonic glide capabilities.
Robert Kelley provides analysis of North Korea's sixth nuclear test, taking a look at what we know so far.
On Wednesday the Director-General of the Organisation for the Prohibition of Chemical Weapons (OPCW), Ambassador Ahmet Üzümcü of Turkey, congratulated Russia on completing the destruction of its chemical weapons stockpile which originally totalled 39 967 agent tonnes (i.e. excluding munition weight).
The announcement that Russia had completed the destruction of its chemical weapons stockpile was rightly applauded as a milestone in multilateral arms control. However, it was also a reminder of the significant part that international non-proliferation and disarmament assistance played in facilitating the implementation of the 1993 Chemical Weapons Convention (CWC).
The Iran nuclear deal has demonstrated that diplomacy can triumph in nuclear non-proliferation: dialogue, rather than military action, can convince states to forgo pursuing nuclear weapons. The European Union has long played an instrumental role in the multilateral diplomacy that produced the historic deal, formally known as the Joint Comprehensive Plan of Action (JCPOA).
Given the transatlantic disagreement over the JCPOA, European countries might feel increasing pressure to focus on Iran’s ballistic missile activities in order to find common ground with the USA. But is the Western perspective on Iran’s missile programme based on an objective threat assessment, and is a punitive approach helpful in addressing it?
The French initiative is a commendable effort to hold facilitators and supporters of CW use in Syria legally accountable and thereby to help ensure that the CWC norms are not fundamentally undermined through inaction or neglect.
The 1987 Treaty on the Elimination of Intermediate-Range and Shorter-Range Missiles (INF Treaty) is on the verge of collapse. The controversy surrounding the treaty has built up over several years and worsened in early 2017 following accusations by the United States that Russia had begun to deploy the missiles during 2016.
This backgrounder provides an overview of ongoing and potential work on measuring states’ achievement of goal 16.4. It begins by outlining the SDG process and how it has sought to overcome the challenges associated with measuring illicit arms flows. It then summarizes the data collection efforts to date and outlines some possible options for filling the gaps that exist.
This topical backgrounder begins with an overview of Russia’s large-scale nuclear modernization programme, which started after the adoption of its state armament programme for 2011–20. It then outlines Russia’s nuclear institutions and how the expenditure is managed within Russia’s federal budget and provides an estimate of Russian spending on nuclear weapons between the years 2010 and 2016.
At a political rally on Saturday, 20 October, US President Donald J. Trump announced that the United States will withdraw from the 1987 Treaty on the Elimination of Intermediate-Range and Shorter-Range Missiles (INF Treaty). This confirms what has steadily been unfolding over the past couple of years: the architecture of Russian–US nuclear arms control is crumbling.
While trying to save the 2015 Joint Comprehensive Plan of Action (JCPOA), or the Iran nuclear deal, some European leaders have stepped up pressure on Iran’s ballistic missile programme, simultaneously demanding talks and threatening sanctions. Iran—which sees ballistic missiles as crucial to the country’s defence—has responded by saying that its missile programme is non-negotiable.
‘Today we have taken a significant step forward in delivering our commitment under the Iran nuclear deal to preserve sanctions relief for the people of Iran.’ These were the words of Jeremy Hunt, Foreign Secretary of the UK, as he introduced the so-called Special Purpose Vehicle (SPV), which is the latest attempt by the E3 (France, Germany and the UK) at preserving the 2015 Iran nuclear deal, or the J
The 2017 Treaty on the Prohibition of Nuclear Weapons (TPNW) was negotiated with the purpose of strengthening the largely unimplemented disarmament pillar of the 1968 Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Yet, one of the main criticisms against the Treaty has been its alleged incompatibility with the NPT. What is one to make of these conflicting claims? And should the increasing number of TPNW ratifications be seen as good or bad news for the international nuclear order?
On 8 May last year, US President Donald J. Trump announced that the United States would pull out of the Joint Comprehensive Plan of Action (JCPOA), which sets limits on Iran’s nuclear programme to ensure that it cannot produce nuclear weapons. Despite the US withdrawal, the JCPOA remains in force; it is a multilateral agreement to which seven of the original eight parties still adhere.
The Nuclear Non-Proliferation Treaty (NPT), which entered into force in 1970, is turning 50 next year. As suggested by discussions at the Preparatory Committee for the 2020 NPT Review Conference (PrepCom)—held in New York on 29 April–10 May 2019—it might not be a happy anniversary. Despite their ritualistic affirmations that the NPT is the cornerstone of the global nuclear order, states parties remained divided on substantive issues.
The states parties to the Biological and Toxin Weapons Convention (BWC) are gathering in Geneva from 29 July to 8 August for a series of Meetings of Experts. Among other topics, states are reviewing scientific and technological developments that impact the objectives of the treaty.
Last week France, Germany and the United Kingdom (the so-called E3) announced that they would trigger the dispute resolution mechanism (DRM) of the 2015 Joint Comprehensive Plan of Action (JCPOA), commonly referred to as the Iran nuclear deal.
While de-escalating the over one month-long stand-off in disputed areas in the Himalayan region, Chinese and Indian troops clashed again on 15 June.
A freeze on the production of tritium is a different way to manage disarmament that will gradually bring an end to nuclear weapons.
In June 2020 Russia made its nuclear doctrine more transparent in terms of why, when and how it would use nuclear weapons. Without naming potential adversaries, Russia is now more explicit about the regional scenarios that could lead to nuclear warfare. It seems to have confirmed that its updated nuclear doctrine is less focused on East Asia, South Asia and the Middle East. At the same time, Russia continues to reserve the right to use nuclear weapons to end conventional military conflicts. This WritePeace blog explores what has changed in the new doctrine and what the changes signal.
Yesterday Honduras became the 50th state to ratify or accede to the 2017 Treaty on the Prohibition of Nuclear Weapons (TPNW), meaning that the treaty will enter into force on 22 January 2021.
Humankind depends on outer space for numerous services, ranging from telecommunications and navigation to disaster management and national security. While the use of space was once associated only with governments, the private sector has become increasingly involved in providing some of these services.
On 14 October 2020, in a statement to the Conference on Disarmament, Indian ambassador, Pankaj Sharma, reiterated India’s commitment to a policy of no first use (NFU) of nuclear weapons.
The international sanctions regime against the Democratic People’s Republic of Korea (North Korea, DPRK) is the strongest and most comprehensive set of sanctions currently in effect against any one country.
A deadly pandemic to control. An urgent nationwide vaccination programme to roll out. An economic crisis to navigate. Political divisions and distrust deep enough to spark mob violence and terrorism. The 46th President of the United States faces a barrage of critical domestic challenges from day one.
Following the declassification of the United States’ National Security Council’s (NSC) US Strategic Framework for the Indo-Pacific, and the transition from Donald J. Trump’s administration to that of President Joe Biden, USA–India relations have once again emerged at the forefront of US security policy. Even though the NSC framework was issued by a departing office, it is noteworthy for both its continuity with the strategies of George W.
Iran’s atomic energy agency announced last week that it had produced 55 kilograms of 20 per cent-enriched uranium in barely four months.
On 13 April, Iran announced its intention to enrich uranium to 60 per cent U-235. This was characterized by Iran as a response to a sabotage of its vast underground enrichment cascades at Natanz two days before.
The nuclear weapon inventories of the nine-nuclear armed states—the United States, Russia, the United Kingdom, France, China, Israel and the Democratic People’s Republic of Korea (DPRK or North Korea)—are largely shrouded in secrecy: only three of the nine states have ever publicly declared the size of their nuclear stockpiles and in recent years there has been a notable shift towards a lower overall level of nuclear weapon-related transparency.
The International Atomic Energy Agency (IAEA) reported on Friday its conclusion that the Democratic People’s Republic of Korea (North Korea) had resumed plutonium production at its nuclear reactor in Yongbyon in early July this year.
Hopes run high that the possessors of the world’s largest nuclear arsenals—Russia and the United States—might finally resume negotiations on nuclear weapon reductions after over a decade of diplomatic deadlock.
On 15 November, Russia conducted a direct-ascent anti-satellite (DA-ASAT) test, destroying one of its own space objects, a defunct satellite, in low-earth orbit. The test captured international attention and was quickly and widely condemned as threatening and irresponsible—not least for the cloud of lethal, uncontrollable debris it created, which will endanger both space assets and human spaceflight for years to come.
On 3 January, the leaders of the five permanent members of the UN Security Council (China, France, Russia, the UK and the USA, the P5) jointly stated that a nuclear war cannot be won and must never be fought. It had never been affirmed simultaneously by all five.
This SIPRI Topical Backgrounder seeks to improve the understanding of hypersonic speed, the nature of hypersonic missile systems, as well as their key subsystems and technologies.
There is an urgent need for the world to come together to address the intertwined environment and security crises, and to deal with the risks they create. This essay draws on research under SIPRI's Environment of Peace initiative and on the authors' own experience of international diplomacy to explore where international cooperation is most needed, and how it could be strengthened.
