Abstract:
Compliance with international humanitarian law (IHL) is recognized as a critical benchmark for assessing the acceptability of autonomous weapon systems (AWS). However, in certain key respects, how and to what extent existing IHL rules provide limits on the development and use of AWS remains either subject to debate or underexplored. This report aims to help states form and express their views on the legal provisions that already do, or should, govern the development and use of AWS, particularly with respect to the required type and degree of human–machine interaction. It maps (a) what limits IHL already places on the development and use of AWS; (b) what IHL demands from users of AWS to perform and satisfy IHL obligations, whether the obligations are of a state, an individual or both; and (c) threshold questions concerning the type and degree of human–machine interaction required for IHL compliance. In its findings and recommendations, the report does not pre-judge the policy response that should regulate AWS. Instead, it aims to provide an analytical framework for states and experts to assess how the normative and operational framework regulating the development and use of AWS may need to be clarified and developed further.

Abstract:
This SIPRI Insights paper explores a series of nuclear transparency and confidence-building measures (CBMs) proposed by military, nuclear, political and regional experts from China, India, Pakistan, Russia and the United States to address nuclear challenges in South Asia. It categorizes these bilateral, trilateral and multilateral measures into doctrinal dialogues and joint threat assessment exercises; communication lines, pre-notification and de-alerting; and development and employment of strategic technologies. The paper then provides a spectrum of viability across which it identifies proposals with the greatest potential, moderate potential and the least potential for reinvigorating nuclear transparency measures and CBMs in South Asia.

Abstract:
Iran is one of the most heavily sanctioned countries in the world. The combination of sanctions on Iran imposed by the United States, the United Nations and the European Union (EU) in response to, among others, nuclear and ballistic missile activities and human rights violations provides for a sanctions environment that is highly complex and difficult to navigate for exporters, financial institutions and humanitarian actors. Particularly in the context of the Covid-19 pandemic, there is renewed attention to the humanitarian impact of sanctions, especially in the case of Iran which became one of the flashpoints of the pandemic. The focus of this paper is on the array of overlapping sanctions and the mitigation of humanitarian impact, with a particular focus on EU sanctions policy and instruments. The paper outlines key milestones and phases in the imposition of sanctions on Iran by the three main sanctioning actors, the USA, the UN and the EU, thus demonstrating the complexity and the at times coordinated or contradictory nature of the different sanctions. It then explores the humanitarian impact of sanctions on Iran by discussing several illustrative indicators and the impact of sanctions on the provision of international humanitarian aid. The paper reviews existing mechanisms to mitigate the humanitarian impact of sanctions and how they could be improved. In the context of the sanctions of Iran, but also beyond, the paper finds that there is a clear need to further strengthen compliance, enforcement and coordination of EU sanctions, including in the context of the Joint Comprehensive Plan of Action. It concludes by providing specific recommendations for the EU and its member states on improving the effective use of sanctions and reducing their humanitarian impact, including through strengthening key instruments and assessment processes, better coordination with the USA and more engagement with humanitarian actors.

14. Enhancing South Asian Nuclear Dialogues: The Implications of Covid-19

Author:

Publication Date:

Content Type:
Policy Brief
Institution:
Stockholm International Peace Research Institute (SIPRI)
Abstract:
Before the global spread of Covid-19, nuclear-armed China, India and Pakistan lacked official diplomatic exchanges to address nuclear weapon-related issues. The pandemic then halted even unofficial dialogues between these countries, which had existed in various bilateral and multilateral formats. As a result, China, India and Pakistan are faced with the challenge of keeping a desirable level of predictability concerning each other’s nuclear postures and capabilities. This SIPRI Policy Brief explores ways of dealing with this challenge and enhancing nuclear dialogues in South Asia. It considers both longer-term developments in the region and the recent implications of Covid-19. The paper finds that bilateral dialogue remains more feasible than trilateral dialogue between China, India and Pakistan. Nevertheless, it argues that these countries may need to address specific issues in broader formats. Emphasized by the Covid-19 crisis, such issues notably include emerging technologies and autonomy. On the one hand, these technologies support diplomacy digitalization, allowing nuclear-armed states to use online and mixed formats to develop nuclear dialogues between them. On the other hand, if applied in the military area, these technologies may affect nuclear postures and capabilities, and contribute to military escalation.

15. Additive Manufacturing for Missiles and Other Uncrewed Delivery Systems: Challenges for the Missile Technology Control Regime

Author:

Abstract:
Additive manufacturing (AM) has become an attractive production technology for the aerospace sector, particularly in the area of missiles, space launch vehicles and uncrewed aerial vehicles (UAVs). Modern AM techniques—often referred to as 3D printing—create objects from feedstock materials such as metallic powders by building them up from the first to the last layer in an iterative process of depositing and fusing layers of material. AM is being used to produce a growing range of components for missiles and UAVs. AM has been recognized to pose a growing proliferation threat and a challenge to existing export controls. The Missile Technology Control Regime (MTCR) has been discussing AM since at least 2013 and seeks to update and harmonize the export controls of the participating states to mitigate the risks posed by AM and ensure the effectiveness of export controls. The export controls prescribed by the MTCR and some of the other regimes already create controls on AM. However, many of these controls are based on overlaps rather than control list items that cover AM by design and may not ensure adequate coverage. This report provides a short introduction to modern AM techniques and describes a range of specific applications of AM in missiles and other delivery systems. It discusses the proliferation risks posed by AM and the engineering and organizational considerations that have to be weighed against the technical capabilities of AM. It analyses the application of export controls to AM, primarily under the MTCR, by discussing controls on AM production equipment; feedstock materials; transfers of technology and technical assistance; and catch-all controls. The report concludes by outlining key measures through which the MTCR could strengthen its efforts to address AM and the proliferation risks and challenges to export controls it poses.

16. Trends in World Military Expenditure, 2020

Author:

Content Type:
Working Paper
Institution:
Stockholm International Peace Research Institute (SIPRI)
Abstract:
World military expenditure in 2020 is estimated to have been $1981 billion, the highest level since 1988—the earliest year for which SIPRI has a consistent estimate for total global military spending. World military expenditure in 2020 was 2.6 per cent higher in real terms than in 2019 and 9.3 per cent higher than in 2011. The global military burden—world military expenditure as a share of global gross domestic product—rose by 0.2 percentage points in 2020, to 2.4 per cent. This increase was largely due to the fact that most countries in the world experienced severe economic downturns in 2020 related to the Covid-19 pandemic, while military expenditure continued to rise overall. This Fact Sheet highlights the regional and national military expenditure data for 2020 and trends over the decade 2011–20. The data is from the updated open-access SIPRI Military Expenditure Database, which provides military spending data by country for the years 1949–2020.

Abstract:
This report provides an overview of views on nuclear postures and escalation affecting South Asia, based on 119 research interviews conducted in 2020 with military, nuclear, political and regional experts from India, Pakistan, China, Russia and the United States. The publication also builds on the findings from a virtual workshop that SIPRI hosted on 8 and 9 December 2020 on ‘Nuclear challenges in South Asia: Views from India, Pakistan, China, Russia, Australia, New Zealand and the USA’. These discussions revealed a variety of interlocking insights on such issues as no first use, lowered nuclear thresholds, conventional and nuclear entanglement and emerging technologies that are shaping strategic stability. The publication consists of five country-focused sections that explore nuclear postures, strategic technologies and escalatory risks, as well as conclusions that offer building blocks for the next steps on engagement. This report was prepared in the framework of the SIPRI project Assessing Nuclear Deterrence Risks and Challenges in South Asia, generously supported by the German Federal Foreign Office.

18. New Technologies and Nuclear Disarmament: Outlining a Way Forward

Special Report

Abstract:
This report sheds light on the impact of recent military-technological advancements on nuclear deterrence and disarmament. Noting that progress towards multilateral disarmament is hardly possible without prior and significant reductions in the largest nuclear weapon arsenals, the report views the resumption of bilateral arms control between Russia and the United States as the most important step towards disarmament at the present moment. It argues that these two countries should move away from their cold war era nuclear doctrines, which seek an ability to win nuclear wars, towards a policy of ‘minimal nuclear deterrence’, that is focused on deterring a nuclear attack. In line with doctrinal changes, further cuts in Russian and US nuclear stockpiles could be achieved by removing nuclear weapons from regional conflict dynamics, meaning that they would no longer serve as a deterrent against conventional aggression. Such a change would help to reduce nuclear risks without undermining regional deterrence, as each side already has robust conventional forces comprised of precision-strike weapons and other advanced military systems. At the same time, the report notes that progress towards nuclear disarmament would be complicated by long-range precision-strike weapons and strategic missile defences, which have raised the bar for credible nuclear deterrence by creating uncertainty about US adversaries’ second-strike capabilities. Lowering that bar and eventually reducing the perceived need for nuclear deterrence will require creative arms control diplomacy, including limits on strategic missile defences; stronger norms against both nuclear and conventional aggression; as well as a clear stigma against nuclear weapons.

19. Strategic Risk Reduction between Nuclear-Weapons Possessors

Author:

Special Report
Institution:
Institut français des relations internationales (IFRI)
Abstract:
The topic of nuclear risk reduction has gained momentum in the international security debate among policymakers, nongovernmental organizations, and experts. The current and expected demise of the traditional arms-control architecture, the renewed strategic competition, and the polarization of the multilateral debate on nuclear weapons have contributed to this renewed salience. Building upon the 2019 G7 Statement on Non-Proliferation and Disarmament, this report defines strategic risk reduction as the set of unilateral, bilateral, and multilateral measures that aim at lowering the likelihood of nuclear weapons use through improved communication, predictability, and restraint, and underlines the need to adopt a strategic approach to nuclear risk reduction. Risks emanating from conflict dynamics between nuclear powers are different in nature and severity from those arising from technical incidents. This report argues that in a context of growing geopolitical rivalries, diplomats should prioritize mitigating the former type of risk. Risk reduction efforts should aim at hindering the most dangerous behaviors in crisis time, through measures focusing both on nuclear forces and on nonnuclear capabilities, whose impact on strategic balances keeps growing. Strategic risk reduction can strengthen international security and strategic stability by complementing arms control measures and deterrence policies. It is therefore crucial to ensure that diplomatic initiatives aimed at limiting nuclear risks do not ultimately, and paradoxically, increase the risk of war. Historical experience shows not only the feasibility of such an approach, but also the concrete security benefits that can be derived from it, by channeling the behavior of nuclear powers in times of tensions, reducing the ambiguity inherent in certain strategies and behaviors, or laying the foundations for international regimes based on operational and strategic restraint as well as on transparency.

Abstract:
United Nations General Assembly (UNGA) adopted the Treaty on the Prohibition of Nuclear Weapons (TPNW) on July 7, 2017. The Treaty is a legal instrument that highlights the humanitarian aspect of nuclear disarmament and provides an alternative to the disarmament approach of the Non-Proliferation Treaty (NPT). Because this Treaty sought to eliminate nuclear weapons, nuclear-weapon states (NWS) and states whose security is based on nuclear deterrence, criticized it for weakening the NPT. However, particular states and supranational nongovernmental organizations, such as the International Campaign for the Elimination of Nuclear Weapons (ICAN) opposed nuclear proliferation by carrying out an active, vigorous campaign to ban nuclear weapons and accomplish the goals of the TPNW. Here, two opposing sides emerged on this rather current issue. This study examines the potential of the European Union (EU) which has members from both sides and has policies towards non-proliferation and controlling nuclear weapons since its foundation, to lead and advance the movement of the ban of nuclear weapons, namely the TPNW process. The study intends to determine the strengths and weaknesses of the EU in its support and contribution to the TPNW process, conducting a further discussion on the issue.
