Abstract:
Since the late 1960s, NATO has sought to balance two objectives—maintaining a strong nuclear deterrent while supporting efforts to buttress strategic stability through arms control and advance nonproliferation and disarmament through the nuclear Nonproliferation Treaty process. The success of this strategy was most evident in the dual-track strategy of deployments and negotiations that led to the signing and implementation of the Intermediate-Range Nuclear Forces (INF) Treaty in 1987. The end of the Cold War also led to substantial cuts in U.S. and Russian strategic systems. Since then, NATO Allies have regularly voiced their support for continuing to pursue these two objectives, including supporting the goal enunciated by U.S. President Barack Obama in 2009 “to seek the peace and security of a world without nuclear weapons.”1 In the last decade, however, Russia’s malign behavior has undermined NATO arms control efforts to the point that it appears traditional arms control will be effectively dead when the New START agreement—already suspended by Russia—expires in 2026. Russian’s invasion of Ukraine, its repeated nuclear saber-rattling in that conflict, and the deployment of non-strategic nuclear weapons to Belarus has also forced the alliance to look to ways to enhance its deterrence, including its nuclear deterrence. Meanwhile, the massive increase in China’s nuclear arsenal and its growing partnership with Russia, is generating additional pressure to increase U.S. nuclear forces as well as questions about the ability of the U.S. to provide extended deterrence simultaneously to Allies in Europe and Asia. Those doubts have been reinforced by political developments in the United States—and in the war in Ukraine—that have raised anxieties about a decoupling of European and U.S. deterrence and defense and led to fresh discussion of a potential “Eurodeterrent.” Meanwhile, developments in North Korea and Iran—and their increasingly close ties with Moscow—further threaten the viability of the already shaky nuclear and missile nonproliferation regimes and have eroded longstanding cooperation between Washington and Moscow to manage nuclear nonproliferation risks in third countries. In response to these developments, Allies and experts, such as the Congressional Strategic Posture Commission, have proposed various adaptations to the alliance’s nuclear posture, including to its nuclear sharing arrangements. This report examines these deterrence proposals, particularly considering how they support the alliance’s other longstanding objectives of arms control, disarmament, and nonproliferation. The paper begins with some background on US/NATO nuclear policy from the end of the Cold War to the further invasion of Ukraine in February 2022. It then delves into changes in Russian nuclear doctrine, Moscow’s nuclear behavior during the Ukraine War, and the Kremlin’s views on future arms control. The report next discusses China’s nuclear modernization and views on arms control and the reaction among NATO and Asian Allies and the international community to these changes. It then discusses potential future U.S. and NATO posture options, including those already being undertaken by NATO or proposed by the US. Congressional Strategic Posture Commission and the State Department’s International Security Advisory Board. It concludes with an analysis of the potential impact of various options on arms control, disarmament, and nonproliferation and offers some policy recommendations.

12. Iran-Russia Defense Cooperation: Current Realities and Future Horizons

Abstract:
Key Takeaways: (1) Big leap forward. Against the backdrop of Russia’s war against Ukraine, the Iran-Russia defense relationship has moved past the previous client-patron dynamic, with Iran emerging as an important provider of defense technology to Russia. Bilateral cooperation has expanded both in degree and in kind. In pre-existing areas of cooperation—such as electronic warfare, space, cyberspace, and military-to-military contacts—engagement has accelerated or deepened. Since 2022, Iran and Russia have also cooperated in entirely new areas. Those have included Iran’s provision of uncrewed aerial vehicles (UAVs), UAV production technology, and UAV training to Russia, alongside Iran’s multifaceted support for Russia’s ground war and assistance with expertise on evading sanctions. (2) The gloves are off. Since February 2022, what were historically key drivers of defense cooperation—a shared animosity toward the United States and the international order it promotes (including in the Middle East), and each side’s interest in military technology that the other side can offer—have increased in importance. Key constraints—Russia’s susceptibility to U.S. or Western pressure, causing it to limit cooperation with Iran; Russian concerns with adhering to nonproliferation norms and export control regimes; Russian reputational concerns over collaborating with Iran; Iran’s inability to pay for Russian technology; or historical mistrust—have become less relevant with Moscow’s growing dependence on Iran and its increased enmity toward the United States and Europe. (3) Growing institutionalization. Amid a general increase in numbers of mutual visits and high-level engagements among military and defense officials, Iran and Russia have taken steps to further institutionalize their defense relationship. Those have included work on a new strategic cooperation agreement to replace the one from 2001, forays into joint production of some weapon systems, and joint efforts to develop the International North-South Transport Corridor and other infrastructure that should provide a further boost to defense cooperation. (4) Thinking about the future in three steps. We propose a three-step methodology to think through the contours of bilateral defense cooperation over the next three to five years. It involves a) extrapolating from current trend lines, drivers, and constraints; b) drawing up inventories of future military needs for each country and identifying the areas in which the other country could help meet those needs; and c) accounting for potential high-impact scenarios and developments that may trigger dramatic shifts in cooperation. The latter include various scenarios of war in the Middle East, the end of Russia’s military campaign against Ukraine, and regime change in either Russia or Iran. (5) Neither a transactional relationship nor a military alliance. Present trend lines and drivers suggest that the relationship is no longer purely transactional and will probably not lapse back into the patron-client dynamic that characterized it prior to 2022, even once the war in Ukraine ends. Iran and Russia each have specific military-technical needs that the other might help meet. That said, beyond Russia’s campaign against Ukraine, Iranian needs from Russia will be greater than Russian needs for advanced technology from Iran. Other constraints—chiefly both countries’ challenges in procuring advanced components because of sanctions, Russia’s aversion to antagonizing the Gulf Arab states, and Russia’s enduring technological superiority in key areas—will also likely continue to act as brakes on the defense relationship, precluding it from developing into a full-fledged military alliance.

13. Nuclear China in the Twenty-First Century: Status and Implications for the World and Europe

Abstract:
In August 2021, shortly after new evidence surfaced that China might be expanding its nuclear arsenal much more extensively and rapidly than previously assumed, Admiral Charles Richard, Commander of the U.S. Strategic Command, described Beijing’s military investments as a “strategic breakout.” He underscored that the “explosive growth and modernization of [China’s] nuclear and conventional forces can only be what I describe as breathtaking,” adding that “that word, breathtaking, may not be enough.” Since then, several senior officials in the United States, Europe, and elsewhere have echoed that message and the final report of the bipartisan Congressional Commission on the Strategic Posture of the United States published in October 2023 concluded that at its current pace, China “will reach rough quantitative parity with the United States in deployed nuclear warheads by the mid-2030s.” The result has been the emergence of work, including by this author, to understand this unprecedented development. This work is in its infancy, however, and more is needed to grasp the scale and scope of Chinese nuclear modernization (especially given that much of it is shrouded in secrecy) as well as its implications for strategic stability, deterrence, and arms control and risk reduction. Existing work has focused primarily on the implications for the United States and, to some extent, the United States and Russia. Yet it is also important to grapple with the implications for Europe, especially the North Atlantic Treaty Organization (NATO), and reflect on actions that Europeans, individually or with others, should take in response.

14. Russia, The Global South and Multilateral Nuclear Diplomacy after the Invasion of Ukraine

Abstract:
Russia’s full-scale invasion of Ukraine in 2022 had a detrimental impact on multilateral nuclear diplomacy. The war caused an earthquake in procedure, paralyzing processes at the International Atomic Energy Agency, the United Nations First Committee, and meetings dealing with the Treaty on the Non-Proliferation of Nuclear Weapons. This was the case even as Russia’s nuclear saber-rattling and occupation of Ukrainian nuclear power plants, and Europe’s recommitment to nuclear weapons, demonstrated the ongoing need for nuclear dialogue. States from the Global South tended to navigate cautiously vis-à-vis Russia across the multilateral nuclear negotiating forums. Amid greater difficulties in forging common positions on nuclear issues related to the Ukraine war, these states were also frustrated with what they perceived as a deprioritization of their interests in multilateral nuclear diplomacy. Western states, especially during the first year of the war, were seen as exercising unwelcome pressure on the Global South to take sides against Russia. Russia, meanwhile, pursued a dual strategy, undermining nonproliferation efforts and chipping away at trust in legacy institutions, while also leveraging these forums in pursuit of greater alignment with states in the Global South. The implications of these different dynamics for the health of the nuclear order may take some time to fully play out, but will likely be profound.

15. A bipartisan Iran strategy for the next US administration—and the next two decades

Abstract:
The United States needs a bipartisan strategy toward Iran that can be maintained across several administrations, one that works patiently and resolutely to counter Iran’s efforts to dominate the Middle East, drive the United States out, destroy Israel, and threaten Arab allies. Pressure to keep Iran from getting a nuclear weapon and to halt its malign regional influence is crucial—but won’t work absent a strategic goal of new negotiations to address both challenges simultaneously. The United States must also counter Iran’s hostage taking, assassinations, and cyber and election meddling by triggering automatic penalties and responses in lockstep with allies.
