Abstract:
Our task was to consider the relative risks and benefits of options for the future U.S. intercontinental ballistic missile (ICBM) force. Our task was not to assess whether the United States should deploy ICBMs at all or change its nuclear strategy and doctrine. In our work, we engaged former officials from Democratic and Republican administrations, nuclear policy specialists from universities and defense and arms control think tanks, and senior military officers, as well as other representatives of combatant commands and the Office of the Secretary of Defense. The current policy, established following a 2014 Analysis of Alternatives (AOA), is to replace the Minuteman III system with a new Ground Based Strategic Deterrent (GBSD) system, now named the LGM-35A Sentinel. Some observers, including members of Congress, have urged reassessing whether deterrence and other requirements could be met more cost-effectively by extending the life of the current Minuteman III missiles and their supporting infrastructure. Department of Defense (DOD) officials note that upgrades that otherwise would have been necessary to sustain the Minuteman III system to 2043 were not undertaken once the decision was made in 2015 to proceed with GBSD. Therefore, they insist, there is no realistic option today to pursue a life extension program for Minuteman III missiles beyond 2030, when they are due to be replaced by GBSD. Although we received considerable data from DOD officials on these topics, the iterative process through which we received information, the unclassified nature of our study, and the limited time available for investigating DOD conclusions left us unable to assess the DOD’s position regarding the technical and cost feasibility of an extended Minuteman III alternative to GBSD. To strengthen public confidence in its decisionmaking on the future ICBM, we believe the DOD should commission an independent, classified technical study (with an unclassified version) to address outstanding questions relating to the options and timelines in the 2014 Analysis of Alternatives, cost estimates, procurement decisions, and adversary threats to future silo-based ICBMs. One of the most salient issues that surfaced in our study is the projected medium-term increase in the vulnerability of silo-based ICBMs to attack by precision conventional weapons. A non-nuclear attack on U.S. nuclear-armed ICBMs would confront the president with the choice of initiating in response what could be a large-scale nuclear attack on adversary homelands (either by launching U.S. ICBMs before they were destroyed or by using other nuclear forces). This threat is likely to materialize well before the notional GBSD service life expiration in 2075. We believe this issue deserves more debate, as it may raise questions about the declining strategic value of a long-term commitment to silo-based nuclear-armed ICBMs inherent in the decision to proceed with GBSD. Our discussions and research also explored issues that senior leaders, including the president, should consider regarding any silo-based ICBM system that the United States would deploy, today and in the future. These include allocating forces to simultaneously deter Russia (possibly in the absence of nuclear arms control, if occurring after the New Strategic Arms Reduction Treaty, or New START, expires in 2026) and a more nuclear-capable China from escalating regional conflicts; confronting possible risks posed by ICBMs overflying Russia to target China; building allies’ confidence in U.S. extended nuclear deterrence; mitigating risks of launch under attack scenarios; and facilitating the negotiation of verifiable nuclear arms control agreements with Russia and China. Consideration of these challenges and issues will be especially important in fashioning the Employment Guidance that will follow from the Nuclear Posture Review.

2. Engaging China on Strategic Stability and Mutual Vulnerability

Abstract:
The United States and Chinese governments, for the foreseeable future, will have the resources to keep each other’s societies vulnerable to nuclear mass destruction. If these governments are not self-destructive, they will want to keep their competition from escalating into armed conflict that could lead to nuclear war. The constructs of strategic stability and mutual vulnerability can help significantly if both governments embrace them and interpret them similarly or even if the leaders of the two countries accurately understand how they differ in their perspectives on them. Unfortunately, to date, on these issues the United States and China are like a quarrelling married couple who tried therapy for one or two appointments, found it dissatisfying, and then alternated in making excuses for not trying again, perhaps with a different therapist or format. Each says they have tried and the other doesn’t listen or understand. Both suspect that the other isn’t saying what they really feel or want; what they really feel is hostility and distrust and what they really want is to get richer and more powerful without being hassled or attacked. It would be easier if they could just go their separate ways, but the property and wealth they depend on will be lost (or at least severely diminished) if they split up or do each other harm. This paper suggests that U.S. and allied interests require persistence in inviting China to dialogue on strategic stability; to demonstrate goodwill, the United States should acknowledge mutual vulnerability as a fact and necessary policy. The need for both moves is reflected in the fact that neither government has defined what it might mean by stability or mutual vulnerability. To help test intentions and prompt harder thinking, the paper plays the role of therapist and offers definitions of both concepts—strategic stability and mutual vulnerability—so that the two sides can critique them more freely and without recrimination. These definitions are broader and deeper than usual, reflecting the growing problem of managing escalation of conventional conflict to nuclear war, the scenario that drives U.S. and Chinese concerns and military posturing. Further, broader definitions are necessary to comprehend the dangers stemming from the entanglement of conventional, cyber, and nuclear weapons and command and control systems. The paper then sketches four benefits of declaring mutual vulnerability, contrary to opponents of the idea, before discussing steps that the United States and China could subsequently take to reflect and build each other’s confidence in such a policy. Finally, if perceived U.S. requirements in the future will be greater than the arsenal needed to deter or defeat Russia or China alone, how will Russia and China be persuaded not to try to build up to balance the additional U.S. force? In other words, if the United States is in two separate but interacting arms races (and deterrence relationships), how could each opponent (China and Russia) be persuaded to negotiate limits on their arsenal lower than the total the United States would insist on possessing to deter two nuclear opponents? Answers to these questions will affect strategic stability and mutual vulnerability of all parties but will take a long time to develop. To begin the process, the paper suggests asking Chinese leaders whether their silence on Putin’s nuclear first-use threats means that China has changed its own policy on nuclear use or that it never took a no-first-use policy seriously in the first place. Is China concerned that the capabilities that the United States and its allies may develop to strengthen defenses against Russia could be used against China too, and if so, might arms control be a wiser approach? Ultimately, the paper suggests that if China and the United States can sustain a process of serious dialogue, they will keep their relationship from worsening even if they cannot formally restrain their competition. And if dialogue leads one to ask the other for deeds to demonstrate goodwill, the paper has suggested some such deeds that could be undertaken with no security hazard and only slight political risk. No one should have the illusion that happiness is in this couple’s future. All this work would be to allow a nonviolent cohabitation that is better than the alternative of destitute divorce or murder-suicide.

Abstract:
The rift between Europe and the United States over Iran is deepening. To regain leverage, the Europeans should engage all eight Gulf states in talks about regional security and nonproliferation. The rift between Europe and the United States over Iran is deepening. Two years of U.S. maximum pressure on Tehran have not yielded the results Washington had hoped for, while the Europeans have failed to put up enough resistance for their transatlantic partner to change course. Worse, the U.S. policy threatens to destabilize the broader Persian Gulf, with direct consequences for Europe. To get ahead of the curve and regain leverage, the European Union (EU), its member states, and the United Kingdom have to look beyond their relations with the Islamic Republic and address wider regional security challenges. The United States’ incipient retreat as a security guarantor and Russia’s increased interest in the region make it necessary for Europe to engage beyond its borders. Despite being barely alive, the 2015 international nuclear deal with Iran offers a good starting point. The Europeans should regionalize some of the agreement’s basic provisions to include the nuclear newcomers on the Arab side of the Gulf. Doing so would advance a nonproliferation agenda that is aimed not at a single country but at the region’s broader interests. Similarly, the Europeans should engage Iran, Iraq, and the six Arab nations of the Gulf Cooperation Council in talks about regional security. Rather than suggesting an all-encompassing security framework, for which the time is not yet ripe, they should pursue a step-by-step approach aimed at codifying internationally recognized principles at the regional level.

4. At a Crossroads? China-India Nuclear Relations After the Border Clash

Abstract:
While both countries may think the situation is under control, dismissive attitudes and misperceptions could end up fueling a dangerous competition. On June 15, 2020, a lethal military conflict over disputed territory in the Himalayas shook the edifice of China-India relations. The clash in the Galwan Valley along their shared border is the gravest military confrontation the two nuclear powers have faced in fifty years. This event and ongoing tensions focus attention on the long-standing but tempered competition between China and India. One of the most interesting puzzles of that relationship is why nuclear weapons, which both possess, have not played a more important role. With the potential for a major reset in China-India ties after the Ladakh crisis, are Beijing and New Delhi finally approaching a long-anticipated crossroads in their nuclear relations? The findings reveal that while Indian security analysts give serious attention to China’s nuclear policy and capabilities, Chinese analysts maintain a dismissive attitude about the relevance of nuclear weapons in China-India relations. The attitude stems from a widely held view that India’s indigenous military technologies are significantly behind China’s and that China will continue widening the gulf between the two countries’ conventional and nuclear capabilities. However, Chinese analysts do not appear to fully appreciate the long-term destabilizing implications of this growing gap. India may feel pressure to build out its nuclear arsenal, and this could further threaten the fragile stability between India and Pakistan. Chinese experts tend to underestimate the role Beijing may have in shaping New Delhi’s threat perception and nuclear strategy.

Abstract:
Beginning with the signing of the Partial Nuclear Test Ban Treaty in 1963, an international arms control regime has limited existing nuclear arsenals and prevented further proliferation of nuclear weapons. But that entire system could soon unravel. Nearly all negotiations on nuclear arms reduction and nonproliferation have come to a stop, while existing treaty structures are eroding due to political and military-technological developments and may collapse in the near future. These strategic and technical problems can be resolved if politicians are willing to work them out, and if experts approach them creatively.

Abstract:
After years of tension, sanctions, and deadlocked negotiations, Hassan Rouhani, Iran's relatively moderate new president, has provided an opening for improved relations between the Islamic Republic and the West. While Rouhani has not ushered in a new Iran, Tehran has adopted a more conciliatory tone on its nuclear program since he took office. This shift is more than just talk, but the West will have to carefully calibrate its response to determine whether Rouhani's changed rhetoric signals the beginning of a new direction for Iran.

Carnegie Endowment for International Peace
Abstract:
Russia as a permanent member of the UN Security Council and nuclear power remains a key player in Eurasia with a substantial leverage in the post Soviet space and, at the same time, the most important neighbour of the EU. However, in the coming decades Russia will face serious challenges to its internal prospects and international position. The further rise of China, negative demographic trends (shrinking population, emigration of well-educated people), substantial increase of the share of Muslim population, degradation of its infrastructure, unsustainability of the current economic model and rampant corruption are the most important factors which will impact on Russia's future and by default on the EU's. Certainly, Russia's democratization would substantially increase its ability to face these challenges and impact positively on EU-Russia relations.

Abstract:
Though most states that want a nuclear weapon can get one through determined effort, the fact remains that most choose not to proliferate. Turkey is no exception. Not even the prospect of a nuclear-armed Iran is likely to push Ankara to develop its own nuclear weapons. The only circumstance where such a scenario would acquire a degree of likelihood is a breakdown in Turkey's security relationship with the United States.

Abstract:
Leaders of the North Atlantic Treaty Organization (NATO) will meet for a summit in Chicago this May to conclude their Deterrence and Defense Posture Review (DDPR), which was intended to be a vehicle for resolving key questions about the future role of nuclear weapons in NATO policy. However, NATO is unlikely to resolve the question of what to do about its forward deployed nuclear weapons before the summit.
