Abstract:
This study is the culmination of four years of work to think through what would be required to track and monitor nuclear warheads in a verification process. It first began in 2021, shortly after President Joe Biden of the United States and President Vladimir Putin of Russia extended the New START Treaty until February 2026; the two presidents also announced the launch of bilateral strategic stability talks. This positive moment in the U.S.-Russian relationship, which became almost unimaginable after the 2022 Russian invasion of Ukraine, was the original impetus for the project. It also launched in the aftermath of the U.S. withdrawal from the Treaty Between the United States of America and the Union of Soviet Socialist Republics on the Elimination of Their Intermediate-Range and Shorter-Range Missiles, commonly known as the INF Treaty. The Russians had been violating the Treaty with the production and deployment of the 9M729 missile, also known in NATO parlance as the SSC-8. All NATO allies concurred with the withdrawal, which the United States completed in August 2019. The effort began with two strands of activity. The study team knew that when the United States and Russia decided to return to the negotiating table, the United States would place a high priority on seeking direct limits on warheads. Prior treaties had focused on controlling and eliminating missiles but had not focused directly on the warheads that armed them. It had long been a goal of the United States to seek direct limits on warheads, in order to more accurately constrain a Russian preponderance in warheads designated for theaterand shorter-range systems.1 However, if such an agreement were negotiated, the European allies would be ill-equipped to participate. On-site inspections under the INF Treaty had ended on May 31, 2001, so it had been twenty years since the allies had had to participate in verification activities. Most had lost expertise and institutional memory; some had never participated at all. “Raising the IQ” of the NATO allies about participating in arms control implementation was thus the first strand of activity. The second strand grew up around a conviction in the study team that the well-practiced verification techniques that had been exercised in INF and strategic arms control treaties since the 1980s could be augmented with new technology and innovative techniques. Thus emerged the emphasis on using cryptography to underpin a unique warhead tracking system. This work took advantage of some of the finest experts in the field of cryptography at Stanford University, and also the extensive experience gained during the Defense Threat Reduction Agency’s many years of work to strengthen warhead protection, control and accounting in Russian Ministry of Defense nuclear warhead storage facilities. This work, which spanned a period of over fifteen years from 1995- 2013, provided the study team with a great depth of knowledge about the normal operating procedures in Russian military warhead facilities. This deep knowledge was vital to developing a concept for the tracking system, providing it with a realism and accuracy that otherwise would not have been possible. These two strands of work culminated in 2022 in a significant study, “Everything Counts: Building a Control Regime for Non-Strategic Nuclear Warheads in Europe.”2 However, the team realized that only one element of warhead verification had been touched—the broad outlines of a system for maintaining and exchanging information over the life of an agreement. Other verification elements such as on-site inspections and particular verification technologies had not been considered. They therefore resolved to expand the scope of work to imagine an entire closed system for nuclear warhead verification. With the cryptographic element as its foundation, the team reviewed the extensive experience of treaties, agreements and other activities such as exhibitions and joint experiments that had been built up over the many years of U.S.-Soviet and Russian cooperation on nuclear weapons control. From this, they created a comprehensive menu of measures that could be considered for a future warhead control regime, calibrating the measures according to the level of their intrusiveness.

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.

Abstract:
Radioactive materials, such as cesium-137 and cobalt-60, are located in more than 100 countries and in every region of the world. They are used widely for medical, scientific, and industrial purposes—but can also be used maliciously as key ingredients in radiological dispersal devices (RDDs), the most notorious type of which is known as a “dirty bomb” which disperses radiological material using explosives. Though responsibility for the development and enforcement of regulations pertaining to the safety, security, and full cycle management of radioactive sources rests with state authorities, thousands of radioactive sources today exist in areas without the clear presence of a state. Such areas are often characterized by conflict and rampant criminal activity as a result of weak or nonexistent governance. Radioactive material located in these contested or poorly governed territories poses a serious risk for regional and global security, as they could be trafficked illegally and used in an RDD or for other malicious purposes anywhere in the world. International and regional organizations face a range of political and legal challenges in helping secure radioactive materials in contested territories since the sources in question are often found beyond the de facto or de jure control of UN-recognized states. Addressing the safety and security of these materials requires stakeholders to navigate uncharted legal issues and play creative roles to secure or transport these materials into safer areas. This report covers one of the few success stories involving the removal or elimination of dangerous radioactive sources from a contested territory. It describes and assesses the lessons learned from the Republic of Moldova’s removal of approximately 2,700 disused radioactive sources and materials from the breakaway region of Transdniestria. Though these materials were located in a territory that is not de facto governed by an International Atomic Energy Agency member state, creative diplomacy by the Republic of Moldova, the Pridnestrovian Moldovan Republic (the unrecognized authorities in Transdniestria), the Organization for Security and Cooperation in Europe (OSCE), and other key stakeholders contributed to the success of this removal operation. The report describes these diplomatic efforts and analyzes the significant political, legal, and technical factors that contributed to the success of this multiyear mission. While recognizing that each country and conflict is unique, we hope that this case study can serve as a successful model of cooperation and confidence building for reducing radiological risks in contested territories around the world.

Abstract:
This study will explain how the United States and like-minded states can still stop, or at least significantly slow down, the bomb’s spread in the Middle East. The historical record as well as the current intentions of potential proliferators in the region suggests this is possible, but Washington will need to start planning now. The three case countries of this monograph – Iran, Turkey, and Saudi Arabia – are all taking aggressive steps toward nuclearization.

5. Arresting Nuclear Adventurism: China, Article VI, and the NPT

Abstract:
Given the current crisis in Ukraine, it’s tempting to consider focusing on Chinese compliance with the Nuclear Nonproliferation Treaty (NPT) to be an academic indulgence. Giving into this inclination, however, would be a mistake. As dangerous as Russia currently is, China will be more threatening in the long run. As we are learning with Russia’s violation of the 1994 Budapest Memorandum, enforcing binding understandings is critical lest violators run roughshod over law and good order. This is true with Russia’s behavior in Ukraine. It is no less so with China’s nuclear weapons buildup and its repeated refusal to join in good faith negotiations to limit its nuclear weapons activities, which is required by Article VI of the NPT. This buildup and refusal clearly flies in the face of China’s legal NPT obligations. The question is what might bring Beijing back into compliance. To get the answers, NPEC held a battery of workshops last fall, followed by a week-long diplomatic simulation. The game participants included U.S., Japanese, and Australian former and current officials and staff as well as outside experts. The group concluded that Beijing is unlikely to comply willingly with the NPT anytime soon, but that U.S. and international security would still be best served by spotlighting Beijing’s nuclear adventurism and suggesting diplomatic off-ramps to arrest its nuclear buildup.

Abstract:
The full research report on the Oral History of the Arms Control and Regional Security (ACRS) Working Group is now available to read and download. The report, authored by Dr. Hanna Notte and Dr. Chen Kane, draws on archival documents and interviews with working group participants to piece together a comprehensive account of the series of ACRS multilateral and bilateral meetings which took place in the early 1990s between states and entities in the Middle East. Dr. Notte and Dr. Kane conducted and compiled dozens of oral history interviews with diplomats and officials who participated in the ACRS multilateral meetings in the early 1990s, following on the heels of the Madrid Conference of 1991. Transcripts of these oral history interviews, the transcript of a critical oral history roundtable on ACRS (convened in November 2021), and previously-unpublished documents on ACRS from US Presidential archives and private collections of American diplomats, are all freely available in a new digital archive, ACRS Oral History Project, hosted on the Wilson Center’s website.

Abstract:
The International Atomic Energy Agency (IAEA) was formed in 1957 to promote the peaceful use of nuclear energy and to inspect civilian nuclear materials and activities to deter military diversions. To decide the frequency of inspections and inspection criteria, the IAEA set its safeguard standards with the objective of assuring “timely detection of diversion of significant quantities of nuclear material from peaceful nuclear activities to the manufacture of nuclear weapons.” The two nuclear weapon designs developed and detonated during World War II were the “gun-type” and “implosion” designs. Because implosion device technology requires much less fissile material than guntype technology, the IAEA significant quantity6 (SQ) values were determined based on the fissile material requirements of nuclear implosion devices like the plutonium-based “Fat Man” detonated over Nagasaki in 1945. Utilizing implosion designs perfected in the late 1940s, however, the explosive yields achieved in 1945 can be produced with much less fissile material. Table 1 lists the fissile material requirements of contemporary nuclear weapon technology. “Low Technical Capability” in Table 1 refers to the Mark III implosion device set off at Nagasaki. “Medium Technical Capability” refers to implosion designs perfected in the late 1940s and “High Technical Capability” in Table 1 refers to the implosion technologies the United States perfected in the 1950s.

Abstract:
Sometimes, slow, steady changes produce revolutionary results. A case in point is missile and space technologies, which Space and Missile Wars: What Awaits will examine. Long-range missiles, satellites, and space launch vehicles used to be high technology exclusive to the superpowers. Now, scores of states have both. As for ballistic missiles and drones, even non-state actors have them, and these systems are far more accurate than anything the superpowers had even at the height of the Cold War. Then, long-range missiles could only be certain of destroying their targets if they were nuclear-armed and wiped out areas as large as cities. Now, drones are so accurate they can pinpoint and kill single individuals. As for space satellite launchers, they originally were derived from nuclear delivery missiles. None were privately owned. Similarly, almost all space satellites were government property and, until 1965, the owners were only American and Soviet. Now, the French, Chinese, Japanese, British, Indians, Israelis, Ukrainians, Iranians, and North Koreans have all launched satellites of their own. In addition, more than 60 nations own and operate their own satellites and increasingly, satellites are launched, owned, and operated entirely by private entities. These developments are nontrivial. They will define the military competitions with China, Russia, and other hostile states for the next two to three decades. Will the spread of accurate missiles embolden weak actors – small states and terrorist organizations – to threaten stronger states with missile attacks against key civilian targets (dams, reactors, petrochemical plants)? Will weak actors be tempted to use accurate drones to assassinate their adversaries’ key leaders? Will such attacks catalyze war, producing modern Sarajevos that draw in nuclear-armed states (e.g. Israel, Pakistan, India, North Korea, or the superpowers)? With so many new space actors, will anyone be able to attribute hostile actions in space? Will states attack satellites mostly in low Earth orbit or geosynchronous orbit? Will the most important attacks come from antisatellite systems based on Earth, in low Earth orbit, or on or near the moon? This volume is designed to answer these questions.

9. China's Civil Nuclear Sector: Plowshares to Swords?

Nonproliferation Policy Education Center
Abstract:
Although much has been said about the fusion of China’s civilian and military sectors, no detailed, unclassified analysis has been done of how Beijing’s “peaceful” nuclear efforts might be exploited to make more nuclear warheads. Even the U.S. Department of Energy’s own explanations of the export restrictions it imposed on “advanced” nuclear exports to China failed to discuss this. This volume is dedicated to clarifying just what the connection could be. Much of it focuses on China’s advanced fast breeder reactor program and its related plutonium recycling efforts. As explained in this volume’s first chapter, “How Many Nuclear Warheads China Might Acquire by 2030,” the least burdensome way for China to achieve nuclear weapons parity with the United States is simply to use the weaponsgrade plutonium that its planned “peaceful” fast breeder reactor and reprocessing programs will produce to make primaries for the two-stage thermonuclear weapons designs they already have perfected. By exploiting this weapons plutonium and the highly enriched uranium and tritium that China can easily access or make, Beijing by 2030 could conservatively assemble an arsenal of 1,270 warheads (nearly as many as the US currently has deployed on its intercontinental missiles).

10. The NPT turns 50: Will it get to 60?

Nonproliferation Policy Education Center
Abstract:
In the next decade, it is all too likely that the past success of the Non-Proliferation Treaty (NPT) in preventing the further spread of nuclear weapons among the world’s nations will be reversed. Three trends make more proliferation likely. First is the decay of nuclear taboos. Second, and arguably worse, is renewed vertical proliferation—the increase in size and sophistication of nuclear arsenals by states that already have them. Third, the technical information to fuel nuclear breakouts and ramp-ups is more available now than in the past. These trends toward increased proliferation are not yet facts. The author describes three steps the international community could take to save the NPT: making further withdrawals from the NPT unattractive; clamping down on the uneconomical stockpiling and civilian use of nuclear weapons materials (plutonium and highly enriched uranium); and giving real meaning to efforts to limit the threats that existing nuclear weapons pose.
