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:
Over recent years, the topic of new and emerging technologies with military applications has ignited a dynamic debate among defense officials, political leaders, diplomats, policy experts, and technical experts. This report provides an overview of the potentially destabilizing effects of several new and emerging technologies and their respective military applications. It aims to provide decision-makers with a better understanding of how to mitigate the risks and reduce the chances that a major power conflict or confrontation escalates to the nuclear level through a range of arms control and risk reduction measures. This report focuses on six significant, distinct emerging military capabilities: hypersonic weapons systems, direct offensive cyberoperations, offensive counterspace capabilities, artificial intelligence (AI)-enabled capabilities, drones, and lethal autonomous weapons systems. This report distills information and ideas from a series of workshops, involving dozens of technical and policy experts in each technology area, that the Arms Control Association conducted in 2021 and 2022. It identifies four overarching themes that highlight the greatest concerns over how the military employment of new and emerging technologies might increase the risk of nuclear weapons use. Increasing the pace of conflict. Increasing uncertainty. Reducing the human role. Incentivizing arms racing. This report identifies near-term risk mitigation measures that are likely achievable now or within the next five years: crisis communications systems, definition establishment, norms, unilateral declarations and actions, and confidence-building measures. This report also outlines long-term measures that are achievable within the next 10 years or beyond: arms control and risk reduction arrangements (e.g., treaties, agreements) that involve more than one country and are more formal than confidence-building measures, although not necessarily legally binding.

Special Report
Institution:

Abstract:
Addressing the threat posed by North Korea’s nuclear weapons is one of the most significant and complex challenges facing the United States. Developing, implementing, and sustaining a verifiable diplomatic process that reduces risk and rolls back Pyongyang’s nuclear weapons program requires a whole of government approach, including constructive contributions from members of the U.S. Congress. While crafting and implementing such an approach will be the prerogative of the Executive Branch, the role that Congress can play in supporting or hindering such a process should not be overlooked. Congress has used an array of tools to put in place conditions for negotiations, express its support or opposition to administration policy, and implement coercive measures toward North Korea designed to punish Pyongyang for its violations of international law and stymie its weapons development efforts. Using survey data and in-depth interviews from the late months of 2020, this report provides insight into how Congress views the North Korean nuclear threat and U.S. approaches to engaging with Pyongyang. More clarity into Congressional views and attitudes may lead to more effective policymaking.

Abstract:
In recent years, the global norm against chemical weapons use has eroded, and it is critical that responsible states take action to reinforce it. Systematic violations of the Chemical Weapons Convention (CWC) and the malign use of chemical agents have continued for nearly a decade without adequate accountability. These incidents risk growing in severity and becoming more widespread for as long as the issue remains unaddressed. Reinforcing the norm against chemical weapons use necessitates a unified global effort to utilize all CWC provisions and to strengthen the consequences that violators face under the treaty and in accordance with international law.

Content Type:
Policy Brief

Abstract:
Upon taking office, the new presidential administration of Joseph Biden will confront a dizzying array of major challenges, not the least of which are related to the risks posed by the world’s most dangerous weapons. Tensions between the world’s nuclear-armed states are rising; the risk of nuclear use is growing; billions of dollars are being spent to replace and upgrade nuclear weapons; and key agreements that have kept nuclear competition in check are gone or are in serious jeopardy. The situation has been complicated by the neglect and poor policy choices of President Donald Trump and his administration. Over the past four years the Trump administration made nearly every nuclear policy challenge facing the United States worse. Fortunately, Biden has a long and distinguished track record when it comes to dealing with nuclear weapons-related security issues. Unlike his predecessor, Biden possesses a strong personal commitment to effective nuclear arms control, nonproliferation, and disarmament that dates back to his early days in the Senate and continued through his last days as vice-president under President Barack Obama. In this analysis we have outlined what we believe to be the five most important sets of nuclear weapons policy challenges and decisions that the new Biden administration will need to address in its first 100 days and beyond, along with recommendations for effectively dealing with each of these policy challenges: Reviving and Advancing the Nuclear Arms Control Enterprise Reducing U.S. Nuclear Weapons Excess Stabilizing the Joint Comprehensive Plan of Action Jump-starting Denuclearization and Peace Diplomacy with North Korea Restoring U.S. Leadership on Multilateral Nonproliferation and Disarmament If pursued, these actions and decisions would make the United States and the world safer from the threats posed by nuclear weapons. These initial steps would also put the administration in a better position to pursue more lasting and far-reaching nuclear risk reduction and elimination initiatives over the next four years.

6. Understanding Hypersonic Weapons: Managing the Allure and the Risks

Author:

Publication Date:

Content Type:
Special Report
Institution:
Arms Control Association
Abstract:
RESEARCH & REPORTS The debate concerning hypersonic weapons has gained increased attention in recent years as the United States has poured billions of dollars—and plans to pour billions more—into accelerating the development of hypersonic weapons and as China and Russia make headway in developing and deploying their own such weapons. The Pentagon is funding no less than eight prototype hypersonic weapons programs with the aim of fielding an initial capability of at least some of those by 2022. The U.S. rush to field hypersonic weapons merits a more critical examination by the Biden administration and Congress given the many unanswered questions about their rationale, technical viability, cost-effectiveness, and escalatory risks. It is past time for Congress to demand these answers before the military begins fielding the weapons in great numbers. This new report outlines the scope of the unanswered questions about the case for hypersonic weapons, details the underappreciated risks to stability posed by the weapons, assesses the viability of arms control as a tool to reduce these risks, and suggests recommended action items for Congress to better its understanding about the Pentagon’s plans for the weapons, eliminate potential redundancies in weapons capabilities, and mitigate stability risks.

7. U.S. Claims of Illegal Russian Nuclear Testing: Myths, Realities, and Next Steps

Author:
Daryl G. Kimball
Publication Date:

Content Type:
Policy Brief
Institution:
Arms Control Association
Abstract:
I n prepared remarks delivered at the Hudson Institute May 29, the Director of the Defense Intelligence Agency (DIA), Lt. Gen. Robert Ashley, Jr., charged that “Russia probably is not adhering to its nuclear testing moratorium in a manner consistent with the ‘zero-yield’ standard outlined in the 1996 Comprehensive Test Ban Treaty (CTBT).” Russia has vigorously denied the allegation. Russian Foreign Minister Sergey Lavrov called the accusation “a crude provocation” and pointed to the United States’ failure to ratify the CTBT. On June 12, Deputy Foreign Minister Sergei Ryabkov said, “we are acting in full and absolute accordance with the treaty ratified by Moscow and in full accordance with our unilateral moratorium on nuclear tests.” The DIA director’s remarks, and a subsequent June 13 statement on the subject, are quite clearly part of an effort by Trump administration hardliners to suggest that Russia is conducting nuclear tests to improve its arsenal, and that the United States must be free of any constraints on its own nuclear weapons development effort, and, indirectly, to try to undermine the CTBT itself—a treaty the Trump administration has already said it will not ratify. The challenges posed by the new U.S. allegations are significant and they demand a proactive plan of action by “friends of the CTBT” governments for a number of reasons.

9. Revitalizing Diplomatic Efforts to Advance CTBT Entry Into Force

Content Type:
Policy Brief
Institution:
Arms Control Association
Abstract:
More than two decades after the opening for signature of the Comprehensive Test Ban Treaty (CTBT), the treaty has near universal support and has established a global norm against nuclear test explosions. The nuclear testing taboo impedes the development of new and more advanced nuclear warhead designs, which helps prevent dangerous nuclear competition, and maintain international security. Although the CTBT has created a norm against testing and a robust technical organization responsible for the operation and maintenance of a highly sensitive global nuclear test monitoring system, the treaty has not entered into force due to the failure of eight key states, including the United States and China, to ratify. The CTBT is and will continue to be an essential pillar in the global nuclear nonproliferation and disarmament enterprise. Moving closer to the goal of the CTBT’s formal entry into force is the task of every CTBT state party, every nuclear Nonproliferation Treaty (NPT) state-party, every state that supports the new Treaty on the Prohibition of Nuclear Weapons, and any other state that considers itself a “responsible” nuclear actor. But in order to realize the full potential of the treaty and to close the door on testing, friends of the CTBT will need to rejuvenate and update their efforts to achieve its entry into force and reinforce the taboo against nuclear testing.

10. The Future of the ICBM Force: Should the Least Valuable Leg of the Triad Be Replaced?

Author:

Policy Brief
Institution:
Arms Control Association
Abstract:
Perhaps the most controversial aspect of the plan to overhaul the nation’s nuclear arsenal is the replacement program for the intercontinental ballistic missile (ICBM) force, the land-based leg of the nuclear triad that also includes submarine-launched ballistic missiles (SLBMs) and heavy bombers. The current deployed fleet of 400 silo-based Minuteman III ICBMs are distributed across three bases touching five states and are expected to be removed from service by the U.S. Air Force in the mid-2030s. A follow-on ICBM system–known as the Ground-Based Strategic Deterrent (GBSD)–is scheduled to replace the Minuteman IIIs (and their supporting infrastructure) on a one-for-one basis between 2028 and 2035. Many have questioned the need for this program, including former Secretary of Defense William Perry, who has argued for eliminating all ICBMs. The latest independent Pentagon acquisition cost estimate to design and build the ICBM replacement ranges from $85 to over $140 billion (in then-year dollars), while the cost to operate and sustain the weapons system over its expected 50-year service life is projected at roughly $150 billion. This ICBM recapitalization cost is but one piece of a larger plan to sustain and upgrade the nuclear arsenal over the next thirty years, with the total price tag projected to exceed $1.2 trillion (in 2017 dollars). Separate modernization programs planned for U.S. conventional forces will require additional outlays. These upgrades will necessitate either a significant and prolonged increase in defense spending, which is unlikely to be forthcoming, or a reallocation of resources within the defense budget. Hard choices will likely be required among competing programs. The Trump administration’s Nuclear Posture Review published in February endorses replacing and upgrading the current Minuteman III force with the GBSD program. It will be up to Congress to assess the program’s cost-effectiveness and evaluate alternatives. This paper will examine this issue in several stages: first, by considering whether ICBMs are needed to hedge against threats to the strategic submarines; second, by discussing their possible benefits and risks as a warhead “sponge”; third, by examining whether ICBMs possess necessary capabilities absent from other legs of the triad; and last, by considering the stability implications of developing a new ICBM with enhanced capabilities. Finally, the paper evaluates alternative options to the costly GBSD program of record.
