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.

2. Reinvigorating South Asian Nuclear Transparency and Confidence-building Measures

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:
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.

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

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.

5. Four Scenarios for the Iran Nuclear Deal

Abstract:
After a hiatus of over five months, negotiations to restore the Joint Comprehensive Plan of Action (JCPOA), commonly known as the Iran nuclear deal, have finally resumed in Vienna. Struck in July 2015 by Iran and a group of six powers – France, Germany and the UK plus China, Russia and the US, as well as the EU (E3/EU+3)–, the JCPOA placed limits on Iranian nuclear activities, while also introducing a highly intrusive inspection regime by the International Atomic Energy Agency (IAEA). The deal is in a comatose state due to former US President Donald Trump’s decision to unilaterally pull out of the agreement and re-adopt all sanctions on Iran in May 2018. In response, since May 2019 Iran has progressively reduced its compliance with its non-proliferation obligations under the deal.
