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.

Special Report
Institution:
Arms Control Association
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.

Arms Control Association
Abstract:
RESEARCH & REPORTS Increasingly in recent years, advanced military powers have begun to incorporate and rely on new kinds or new applications of advanced technologies in their arsenals, such as artificial intelligence, robotics, cyber, and hypersonics, among others. The weaponization of these technologies may potentially carry far-ranging, dangerous consequences that expand into the nuclear realm by running up the escalation ladder or by blurring the distinction between a conventional and nuclear attack. Arms control, therefore, emerges as a tool to slow the pace of weaponizing these technologies and to adopt meaningful restraints on their use. This report examines four particular new kinds or new applications of technologies— autonomous weapons systems, hypersonic weapons, cyberattacks, and automated battlefield decision-making—and proposes a framework strategy aimed at advancing an array of measures that all contribute to the larger goal of preventing unintended escalation and enhancing strategic stability.

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.

Policy Brief

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.

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.

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

Author:

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.

8. 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.

10. U.S. Nuclear Excess: Understanding the Costs, Risks, and Alternatives

Policy Brief

Abstract:
In a little-noticed comment before his controversial July 2018 summit meeting with Russian President Vladimir Putin in Helsinki, U.S. President Donald Trump characterized his government’s multi-hundred billion dollar plans to replace the aging U.S. nuclear arsenal as “a very, very bad policy.” He seemed to express some hope that Russia and the United States, which together possess over 90 percent of the planet’s nuclear warheads, could chart a different path and avert renewed military and nuclear competition. The Helsinki meeting, however, did not produce any agreement on nuclear weapons and Trump has so far shown little interest in a different nuclear spending path. Quite the opposite, in fact.“We have far more money than anybody else by far,” Trump said last October. “We’ll build [the U.S. nuclear arsenal] up until” other nuclear-armed states such as Russia and China “come to their senses.” Citing a deteriorating international security environment, the Trump administration is pursuing a significant expansion of the role and capability of the U.S. nuclear arsenal. In addition to continuing full speed ahead with its predecessor’s plans to replace the nuclear triad and its associated warheads on largely a like-for-like basis, the administration is proposing to broaden the circumstances under which the United States would consider the first use of nuclear weapons, develop two new sea-based, lowyield nuclear options, and lay the groundwork to grow the size of the arsenal. At the same time, key U.S.-Russian nuclear arms control agreements, which serve to regulate the nuclear balance and prevent unconstrained nuclear competition, are now in serious doubt. The Trump administration has announced the United States will leave the landmark 1987 Intermediate-Range Nuclear Forces (INF) Treaty in August 2019 unless Russia returns to compliance with the pact, and expressed hostility towards extending the 2010 New Strategic Arms Reduction Treaty (New START). New START expires in 2021 but can be extended by up to five years subject to the agreement of Washington and Moscow. In short, the Trump administration is preparing to compete in a new nuclear arms race while simultaneously increasing the likelihood of such a contest. The projected cost of the proposed nuclear spending spree is staggering and it is growing. The United States currently plans to spend nearly $500 billion, after including the effects of inflation, to maintain and replace its nuclear arsenal over the next decade, according to a January 2019 Congressional Budget Office (CBO) report. This is an increase of nearly $100 billion, or about 23 percent, above the already enormous projected cost as of the end of the Obama administration. Over the next 30 years, the price tag is likely to top $1.5 trillion and could even approach $2 trillion. These big nuclear bills are coming due as the Defense Department is seeking to replace large portions of its conventional forces and internal and external fiscal pressures are likely to limit the growth of—and perhaps reduce—military spending. “We’re going to have enormous pressure on reducing the debt which means that defense spending—I’d like to tell you it’s going to keep going up—[but] I’m not terribly optimistic,” Alan Shaffer, deputy under secretary of defense for acquisition and sustainment, said in February 2019. This report outlines the ways in which the Trump administration’s nuclear strategy is unnecessary, unsustainable, and unsafe. It describes three realistic options to reduce spending on nuclear weapons while still maintaining a devastating nuclear deterrent. Scores of billions of dollars could be saved or redirected to higher priorities by eliminating, delaying, or scaling back the administration’s proposals for new delivery systems, warheads, and infrastructure.
