Abstract:
The United States under President Donald Trump has adopted an ambiguous position on European security. Although no immediate risk of abandonment is apparent, European countries are rethinking their defence strategies in case the US declines to support them, or provides only partial support, in a crisis. This discussion is particularly sensitive in relation to nuclear weapons, the ultimate deterrent, for which European countries depend extensively on the United States. We argue that a possible future US withdrawal from European nuclear security will force European countries to face a policy trilemma. If they stick to the existing policy framework of no proliferation and no joint deterrence, they expose themselves to nuclear blackmail, should the US withdraw its external guarantee. If they want to protect themselves from nuclear blackmail, they must choose how to provide nuclear security: either collective nuclear security, which would compromise some national sovereignty, or independent provision by individual countries, leading to nuclear proliferation in Europe. Having established that uncontrolled proliferation is an inferior outcome to some form of joint deterrence, we identify four main alternatives: an extension of the Franco-British nuclear deterrent; an extension complemented by a jointly financed expansion of existing deterrence; the absorption of the French (and perhaps British) nuclear arsenals into a European arsenal; and the construction of a separate European submarine deterrent (with Europe using French or British technology or developing new technology). We also discuss briefly forms of non-nuclear deterrence, which however would likely be a complementary rather than a substitute for a nuclear deterrent. We compare these options using a set of parameters: strategic autonomy and credibility, changes to treaties (including non-proliferation), costs, capabilities and readiness. Our analysis shows that all options have advantages and disadvantages, but some are politically, financially and militarily more feasible.

Abstract:
In the context of deep changes to the international security environment, especially the war in Ukraine, the risks of nuclear proliferation seem quite high, especially in the Middle East and East Asia. Four categories of factors have been identified that might trigger an escalation. Firstly, changes in the international security environment, including heightened competition among major powers, could increase pressure for proliferation in regions like Europe, Asia, and the Middle East. Secondly, the declining ability of the United States to enforce non-proliferation regimes may lead allies to seek nuclear capabilities due to concerns over U.S. reliability. Thirdly, failures by nuclear powers to uphold disarmament commitments and the emergence of the Treaty on the Prohibition of Nuclear Weapons could undermine non-proliferation norms. Lastly, the war in Ukraine highlights the potential use of nuclear threats in conflicts, reinforcing the perception of nuclear weapons as crucial for national security. While there are reasons to anticipate growing proliferation risks, historical precedent suggests that these risks can be managed. Concerns over U.S. reliability and disarmament failures have been addressed through coercion and reassurance in the past. Additionally, the impact of conventional wars supported by nuclear deterrence has been contained. While some risk factors are novel, such as the decline of the U.S. nuclear industry and the emergence of the Treaty on the Prohibition of Nuclear Weapons, their decisive impact remains uncertain. The implications for the Middle East and East Asia vary. Allies like Japan and South Korea may be convinced to remain non-nuclear due to U.S. security assurances, while adversaries like Iran could be incentivized to pursue nuclear capabilities amid declining effectiveness of U.S. sanctions. If Iran acquires nuclear weapons, it may pressure Saudi Arabia to follow suit, potentially leading to regional proliferation dynamics. Thus, great powers and the international community need to step in to manage proliferation triggers by maintaining a focus on nonproliferation in their statecraft.

3. Requirements for nuclear deterrence and arms control in a two-nuclear-peer environment

Abstract:
After decades of seeking to reduce the role of nuclear weapons in international relations, the United States is now grappling with a global landscape marked by intense strategic competition and the growing salience of nuclear weapons—problems that will likely persist for years to come. Over the past year, Russia compounded its aggression in Ukraine with nuclear saber-rattling, modernizing and expanding its nuclear forces over the past decade. Furthermore, Russia’s possession of a substantial inventory of theater nuclear weapons continues to threaten regional deterrence. Meanwhile, in Asia, Beijing is pursuing an unprecedented surge in its nuclear capabilities. If current trends persist, China is projected to possess about 1,500 nuclear warheads by 2035.1 While China was once viewed as a secondary nuclear power, its substantial investment in its nuclear arsenal—including the launch of a third ballistic missile early-warning satellite in 2022 and advancements in land-based ballistic missiles, aircraft, submarines, and hypersonic missiles—positions China to become a near-equal nuclear power in the coming decade. These trends mark a historic shift. For the first time in its history, the United States must face two near-peer nuclear competitors simultaneously. At the same time, Russia’s suspension of its compliance with the New START agreement in 2023 has significantly weakened the last strategic arms control framework established in the Cold War and post-Cold War eras. This move leaves scant provisions governing the future of nuclear capabilities among the United States and its adversaries. For over half a century, Washington and Moscow negotiated to establish treaties that imposed limits on their nuclear arsenals, aiming to manage their nuclear rivalry and mitigate the risk of nuclear conflict. This process served the national security interests of both sides by curbing weapons and activities that could jeopardize deterrence, safeguarding strategic stability, offering insights into nuclear capacities, and potentially steering military competition toward less perilous avenues. However, shifts in the global security landscape have altered this calculus. The Russian Federation, much like the Soviet Union before it, has insisted that future agreements factor in the nuclear capabilities of Britain and France. On the other hand, the United States now confronts a security environment featuring two nuclear-armed adversaries—Russia and China—whose forces will potentially pose significant threats to the United States and its allies. This evolving security landscape may prompt the United States to reevaluate its assessments of its deterrence and arms control requirements. But how should the United States approach this problem?

4. Constraining Iran’s Nuclear Potential in the Absence of the JCPOA

Abstract:
Since 2019, Iran has significantly expanded its sensitive nuclear activities, which has irreversibly altered the pathways available to Iran if the decision were made to develop nuclear weapons. The proliferation risk posed by Iran’s nuclear advances is amplified by the monitoring gaps that Tehran created by reducing IAEA access and monitoring. Iranian officials have long denied any interest in nuclear weapons but there are new signs that Iran may rethink the prohibition on nuclear weapons if security conditions change. Iran’s technical expertise cannot be reversed, and its nuclear infrastructure is less vulnerable to attack. As a result, military strikes against Iran would set back the program, but only temporarily, and risk driving Tehran to develop nuclear weapons. Tehran has signaled its willingness to de-escalate tensions, including on its nuclear program. Leaders in Washington should seize this opportunity to incentivize Tehran to take steps that increase monitoring of its nuclear program and reduce proliferation risk. The experience of the 2015 nuclear deal demonstrated the limitations of transactional bargaining. The regional nuclear environment also has shifted since 2015 and there is an increased risk that additional states will seek to match Iran’s capabilities. The United States should be thinking now about alternative frameworks for negotiating a longer-term nuclear deal, or series of deals, that take into account Iran’s nuclear advances and mitigate regional proliferation risks.

Abstract:
On November 7, 2023, Russia formally withdrew from the Convention on Arms in Europe (CFE), and in December, NATO suspended the agreement, leading to the collapse of one of the largest arms control treaties since the Cold War. The main goal of the treaty was to ensure security and stability in Europe through conventional arms control; through periodical monitoring, information was shared and trust was built between the parties. The new reality, emerging right after the cancelation of the agreement, has become the subject of active discussion in political and academic circles. Our paper aims to analyze the essence and meaning of the CFE agreement, the reasons for it being cancelled, and the expected results

6. Nuclear arms control policies and safety in artificial intelligence: Transferable lessons or false equivalence?

Abstract:
Multiple nuclear arms control treaties have collapsed in recent years, but analogies associated with them have returned as possible inspiration to manage risks stemming from artificial intelligence (AI) advancement. Some welcome nuclear arms control analogies as an important aid to understanding strategic competition in AI, while others see them as an irrelevant distraction, weakening the focus on new frameworks to manage AI’s unique and unprecedented aspects. The focus of this debate is sometimes too narrow or overly selective when a wider examination of arms control geopolitics can identify both irrelevant and valuable parallels to assist global security governance for AI. Great power leaders frequently equate AI advancement with arms racing, reasoning that powers lagging behind will soon see their great power status weakened. This logic serves to intensify competition, risking a spiral into more unsafe AI practices. The global norm institutionalization that established nuclear taboos can also stigmatize unethical AI practices. Emphasizing reciprocal risk reduction offers pragmatic starting points for great power management of AI safety.

Abstract:
National actors working in small arms control and on women, peace, and security (WPS) share commitments to reduce suffering, maintain peace and security, and contribute to the realization of the Sustainable Development Goals (SDGs). Yet, while these cross references are increasingly commonplace in the international policy framework, this does not often translate into harmonized references in national action plans (NAPs) on WPS and small arms control. Meaningful Partners: Opportunities for Collaboration between Women, Peace and Security, and Small Arms Control at the National Level—a Briefing Paper from the Small Arms Survey’s Gender-Responsive Arms Control project—identifies potential avenues for future work to better harmonize efforts related to WPS and small arms control, and improve the effectiveness of both policy areas in achieving their objectives.

Institution:
Small Arms Survey
Abstract:
Since 1970, armed groups have hit dozens of civilian aircraft with man-portable air defence systems (MANPADS), killing more than 1,000 civilians. The international community has taken numerous steps to reduce illicit proliferation, but armed groups in the Middle East and North Africa (MENA) region continue to acquire and use these systems. Persistent Perils: Illicit MANPADS in the MENA Region—a new Report from the Small Arms Survey’s Security Assessment In North Africa (SANA) project—provides an in-depth analysis of the proliferation of MANPADS in North Africa and the Middle East from 2015–23. Drawing on imagery and data collected since 2015 to identify the type, model, generation, and country of design/manufacture of illicit MANPADS in the region, the Report assesses the implications of recent proliferation patterns for regional security and international norms and agreements.
