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.

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?

3. Tailored Deterrence Strategy on the Korean Peninsula

Abstract:
Over the last decade, the most significant change in the international strategic environment has been the reemergence of a great power rivalry between the U.S. and its European and Asian allies on one hand and Russia and China on the other. This trend began in the second term of President Obama, with the Russian invasion of Crimea in early 2014 and the Chinese construction of a network of military bases in the South China Sea beginning around 2013. Since then, the trend has sharpened. The Russian invasion of Ukraine in February 2022 has locked the U.S. and its North Atlantic Treaty Organization (NATO) allies against Russia in a long-term struggle for the survival of Ukraine and future of European security. In Asia, tensions between Beijing and Washington have become worse, as both the Trump and Biden admіnistrations pursued economic measures against China, and as China appears to be building military options to unify Taiwan and the mainland by force. The reemergence of great power rivalry has important nuclear dimensions, increasing concerns about “strategic stability” – the nuclear balance among the great powers – and the risk of nuclear conflict. The Ukraine war has lowered the nuclear threshold. Russia has deployed tactical nuclear weapons in Belarus and threatened to use tactical nuclear weapons to discourage NATO intervention or assistance to Ukraine. The New Strategic Arms Reduction Treaty (New START) - the last remaining arms control treaty limiting U.S. and Russian nuclear arsenals - expires in February 2026, and Russia has refused U.S. offers to negotiate a new treaty as long as the U.S. is assisting Ukraine. In the meantime, Russia continues to develop an array of exotic nuclear delivery systеms intended to overcome U.S. missile defenses, including hypersonic reentry vehicles, nuclear-armed submarine drones, and nuclear anti-satellite weapons. China is pursuing an unprecedented nuclear build-up, including new strategic bombers, more advanced nuclear-armed submarines, and three new missile bases with more than 300 silos for solid fuel ICBMs with multiple reentry vehicles. According to U.S. Department of Defense estimates, China has more than 500 operational nuclear warheads as of May 2023 and will “probably have over 1,000 operational nuclear warheads by 2030” (U.S. Department of Defense 2023a). Like Russia, China is also pursuing hypersonic reentry vehicles, anti-satellite weapons, and strategic cyber operations. Some analysts fear that China’s nuclear build-up will make it more confident that it can deter U.S. intervention in the face of a Chinese invasion of Taiwan or increase the risk that a U.S.-China confrontation over Taiwan will escalate to nuclear use. To address the reemergence of great power threats, the U.S. has introduced the concepts of “tailored deterrence” and “integrated deterrence” into its nuclear doctrine. According to the Trump admіnistration Nuclear Posture Review, released in February 2018, The United States will apply a tailored and flexible approach to effectively deter across a spectrum of adversaries, threats, and contexts. Tailored deterrence strategies communicate to different potential adversaries that their aggression would carry unacceptable risks and intolerable costs according to their particular calculations of risk and cost (Office of the Secretary of Defense 2018). The tailored deterrence concept was also adopted by the Biden admіnistration in its October 2022 Nuclear Posture Review, saying, Central to U.S. deterrence strategy is the credibility of our nuclear forces to hold at risk what adversary leadership values most. Effectively deterring – and restoring deterrence if necessary – requires tailored strategies for potential adversaries that reflect our best understanding of their decision-making and perceptions (Office of the Secretary of Defense 2022). Building on the concept of tailored deterrence, the Biden admіnistration Nuclear Posture Review (NPR) also introduced the concept of “integrated deterrence,” which is based on the idea that traditional nuclear deterrence can be reinforced by non-nuclear capabilities. According to the NPR, The role of nuclear weapons is well established and embedded in strategic deterrence policy and plans. Non-nuclear capabilities may be able to complement nuclear forces in strategic deterrence plans and operations in ways that are suited to their attributes and consistent with policy on how they are to be employed. A pragmatic approach to integrated deterrence will seek to determine how the Joint Force can combine nuclear and non-nuclear capabilities in complementary ways that leverage the unique attributes of a multi-domain set of forces to enable a range of deterrence options backstopped by a credible nuclear deterrent (Ibid.).

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

Content Type:
Working Paper
Institution:
Arms Control Association
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.

5. Inside the ICBM Lobby: Special Interests or the Public Interest?

Author:

Policy Brief
Institution:
Quincy Institute for Responsible Statecraft
Abstract:
The nuclear weapons lobby is one of the most powerful forces in the military industrial complex. 1 The lobby’s current priority is advocating for the $315 billion Sentinel program to build a new Intercontinental Ballistic Missile (ICBM). The program has faced controversy over both its utility and its cost, including a cost increase of a whopping 81 percent since 2020. The key champions of the Sentinel program are the Senators from Montana, North Dakota, Utah and Wyoming — states that are home to major ICBM bases or host major work on the Sentinel program. The group — known as the Senate ICBM Coalition — stresses the Sentinel’s purported role in strengthening nuclear deterrence as well as its creation of jobs in the states they represent. However, other members of Congress and ex–defense officials have raised urgent concerns about the Sentinel program, questioning the deterrence rationale that undergirds it and raising the alarm over the risk of accidental nuclear usage. Despite claims about Sentinel’s economic benefits, it remains unclear how many jobs the program will actually create. Weapons contractors — led by the Sentinel’s prime contractor, Northrop Grumman — play a central role in the ICBM lobby. Since 2018, members of the strategic forces subcommittees of the House and Senate Armed Services Committees have received $3.8 million from the 11 major Sentinel contractors. In total, ICBM contractors have donated $87 million to members of Congress in the last four election cycles alone. Contractors’ influence efforts are aided by the fact that senior government officials and members of Congress often secure jobs in the arms industry when they leave government; this provides them the opportunity to lobby former colleagues. In all, the 11 ICBM contractors have spent $226 million on lobbying in the past four election cycles. They currently employ 275 lobbyists, the vast majority of whom have passed through the revolving door from influential positions in government. The Sentinel program should be scrutinized as part of a larger reassessment of U.S. nuclear policy. The 2023 report of the Congressional Commission on the Strategic Posture of the United States endorses the program and calls for a comprehensive nuclear weapons build-up, including the possible placement of multiple nuclear warheads on ICBMs — a highly aggressive strategic posture that has not been in place since the Cold War. A high number of Commission members have ties to the nuclear weapons industry, including its co–chair Jon Kyl, who was once a lobbyist for Sentinel prime contractor Northrop Grumman. Congress must weigh the dubious benefits of the Commission’s proposals against the significant risks and costs its recommendations would entail if carried out.

6. US strategy and force posture for an era of nuclear tripolarity

Author:

Content Type:
Working Paper
Institution:

Abstract:
The term “nuclear tripolarity” describes a world in which China has joined the United States and Russia as a leading nuclear power. As China modernizes its existing nuclear forces and deploys new weapons, it is on track to roughly double its deployed nuclear arsenal in the next few years—from approximately 350 to 700 deliverable warheads. The US Department of Defense projects that China will go further, expanding its arsenal to at least 1,500 warheads by 2035.1 At those force levels, China’s arsenal would be comparable to US and Russian deployed nuclear forces, currently capped at 1,550 by the New START Treaty.2 What are the consequences of emerging tripolarity for US nuclear strategy and force posture? If the United States retains its current approach to nuclear force planning, the growth of China’s arsenal (and the ongoing modernization of Russia’s nuclear weapons) will likely compel the United States to significantly increase its own arsenal. The easiest way to do so would be to upload one to two thousand additional warheads from US reserves onto existing delivery systems when the New START treaty expires in 2026. Unfortunately, a major increase in US forces would likely mark just another step in an intensifying arms competition among the three leading nuclear powers, since China and Russia would then feel pressure to respond.

8. Is the Pursuit of Nukes Driven by Leaders or Systems?

Abstract:
Nuclear weapons are widely regarded as one of the most lethal aspects of military arsenals ever created. As such, international relations and security experts have long been concerned about their proliferation. To prevent the spread of nuclear weapons, both policymakers and academic researchers have focused on what are commonly thought to be the primary drivers of proliferation: security concerns and domestic politics and economies. This brief examines another important driver: the role of national leaders themselves. Based on a study of 1,400 leaders in office between 1945 and 2000, author Ellen Park shows that leader personality and experience drive decisions about whether—or not—to pursue nuclear weapons, a finding that holds true across countries (rather than being limited to a few unique cases). Put simply, the pursuit of nuclear weapons is systematically influenced by certain attributes of leaders, such as college major, socioeconomic background, and military and international experience. To predict when and where the spread of nuclear and other emerging technologies will emerge next, policymakers should promote interdisciplinary dialogue to cultivate leader profiles and expand their use.

Abstract:
Yu-hwan Koh, the President of the Korea Institute for National Unification, acknowledges the progress made in maintaining the Nuclear Non-proliferation Treaty regime and bolstering extended deterrence capabilities against North Korean nuclear threats through the Washington Declaration. Nevertheless, he underscores the lack of a fundamental solution to halt further advancements in Pyongyang's nuclear capabilities. Dr. Koh emphasizes the importance of establishing normalized relations between the United States and North Korea, particularly considering that North Korea now possesses nuclear weapons and is unlikely to return to denuclearization talks. In response, he reiterates the significance of the ROK-US alliance in strengthening the Three-Axis system and developing new weapon systems that can effectively counter North Korea's nuclear capabilities.

Abstract:
Cheol-wun Jang, a research fellow at the Korea Institute for National Unification, emphasizes that while North Korea has made significant strides in long-range ballistic missiles, it has not been successful in the area of artificial satellites. Up until now, Pyongyang has had limited engagement in exchanges with major advanced countries involved in space development. Dr. Jang predicts that North Korea is expected to continue its independent pursuit of space development, which will hinder the country’s progress in the satellite sector in the near future.
