    Thinking about a future Iran Nuclear Deal

    NTI’s Eric Brewer joins us to unpack how Iran’s nuclear program has transformed since the JCPOA era — and what that means for any future nuclear agreement, which we acknowledge may be quite far off. We talk about Iran’s stockpile of enriched uranium, the lack of IAEA access, new underground facilities, and years of experience with advanced centrifuges, and how these changes create a fundamentally different technical baseline than negotiators faced a decade ago. The three of us also talk about Iran’s intentions moving forward, summarizing recent public reporting and the disappearance of the IC’s long‑standing assessment that Iran was not pursuing key weaponization activities. We also discuss the ongoing conflict, starting with Operation Midnight Hammer, and how these events may have shifted Tehran’s strategic calculus with the old deterrence architecture weakened—its proxy network and missile forces have been degraded—whether Iran’s leadership might now view a nuclear weapon as the only reliable insurance policy. Finally, we talk about what a future deal (and additional policy measures) would actually entail. We cover building blocks on the topics of weaponization bottlenecks, regional missile transfers, and a more muscular counterproliferation posture, as well as what may be an exponentially more difficult verification mission, with new mechanisms for access, dispute resolution, and monitoring of military‑linked sites. Show notes and a few publicly available resources we referenced: We started out hoping to go into slightly more technical detail on JCPOA and future JCPOA provisions, but kept the conversation at a higher level for the sake of greater appeal to a wider array of listeners.

    Part III of our series on New START

    To close out (for now…) our three part series on New START and its pending expiration, Rebeccah Heinrichs and Frank Miller join Vipin, Austin, and I to explain why they think the United States should let the agreement expire without a continuation of the central numerical limits, as Russia has proposed. Our conversation touched upon Russia’s behavior in implementing the treaty, compliance record, the relevance of New START-like limits given the dilemmas facing the United States, the study of nuclear weapons policy and deterrence and the role arms control plays in this domain, and advice for new students and professionals looking to contribute to the field. As always, please feel free to leave us comments and questions and we’ll look to address them in an upcoming podcast.

    Part II of our three part series on New START

    Arms control diplomacy is, like many other areas of government policy-making, hard to understand without experiencing directly. How defense strategy, political science, technology, and area studies combine with personalities, time pressure, and interagency tensions is difficult to describe - but these elements collide together in a highly concentrated fashion during an arms control negotiation. Greg Dwyer and Mike Albertson both served on the New START delegation at different points in their careers, and shared their experiences in part II of our New START series. Both spent time early in their careers “backbenching” the treaty negotiations in Geneva, and then carried leadership responsibilities on behalf of their agencies as part of the regular New START delegation that would travel to Geneva to engage in implementation discussions with Russian counterparts in the Bilateral Consultative Commission, a body created by the Treaty to ensure both parties had a venue to raise and address implementation and compliance questions. We all worked together on New START, so there is a fair amount of reminiscing in this episode, but Greg and Mike also provide a detailed glimpse into the work that goes on behind the scenes in arms control negotiation and implementation. I hope young professionals wondering what it’s like to work in this field take particular interest in this episode. As always, please feel free to send comments or question our way here or in the subscriber chat. Background reading (stuff I haven’t shared in previous posts, but seem pertinent to New START expiration). * I really hope DoW doesn’t get rid of this resource - a searchable treaty text with can help you go down a few of the rabbit holes we referenced during the podcast. * a 2024 RAND report on post-New START options. * Erin Dumbacher’s recent CFR post on managing Putin’s offer to maintain New START limits. * Frank Jones’ book “Obama on the Bomb,” covering New START and arms control efforts during the Obama administration.

    Shibboleths or Not? Introducing Matthew Sharp to the Pod

    Before the holiday break, Vipin contributed a new post to the Strategic Stability Substack (I know, two in one year, how can he keep up this lightning pace) titled “Four Shibboleths of Nuclear Strategy.” In the post, Vipin asks whether we should take for granted four strong, consistent ideas that appear in nuclear policy debates: (1) strategic stability is “good,” (2) arms races are “bad,” (3) escalation is uncontrollable, and (4) deterrence is the threat that leaves something to chance (trying to surmise what Schelling really meant). This post highlighted some important questions about how we discuss nuclear policy: do the terms we use still hold the same relevance today as they did when they were first created, do we even operate from the same definitions as one another, and how have changes in the world changed how we think about policy underlying these principles? And to demonstrate how good of a sport he truly is, Vipin not only brought a new senior fellow on board at MIT’s Center for Nuclear Security Policy, but one who immediately wrote a substack post in response to Vipin’s “Four Shibboleths.” Matthew Sharp joins the group following a long career in government, with stops at the Department of State, NSC, and U.S. Mission to Vienna where he worked on IAEA issues. Matthew described the journey his brain took as he thought about Vipin’s post, elaborating on how he thinks about the risk of increased numbers via either horizontal or vertical proliferation, and shares his own view of the importance of strategic stability as a goal, and valuable if thought of as reaching a stable equilibrium. We saved a little time to talk about South Korea’s interest in nuclear submarines - what operational value nuclear-powered submarines can provide, and what kinds of activities South Korea may need to begin in cooperation with the IAEA, drawing upon Matthew’s past experience working on AUKUS implementation. We spent our last few minutes tackling a mailbag/chat question regarding the science behind nuclear winter and its place in nuclear policy discussions and international debate. Things to read: Sharon Squassoni in The Bulletin: “How nuclear submarines could pave the way for nuclear weapons in South Korea“ Brent Sadler for Heritage: “The Optimum Pathway for Building Nuclear Submarines With South Korea and Japan” James Scouras, Lauren Ice, Megan Proper at JHU/APL: “Whatever Happened to Nuclear Winter?” Strategic Simplicity is an independent publication.
