Strategic Simplicity Podcast

Austin and Matthew are busy writing to keep the free, independent, and lazily managed substack alive, with two recent articles:In “The Perils of Shallow Theory Redux,” Austin responds to a recent article by former DoD colleague Erin Dumbacher, who recently wrote “America Doesn’t Need More Nuclear Weapons” in Foreign Affairs.Matthew Sharp recently wrote “Parity in Arms Control,” where he explores the role parity plays in…arms control (and why it appears in arms control when it does).Intro/outro music licensed by Soundstripe: “The Iron Curtain” by Wicked Cinema.Recording and edits through Riverside.fm.Strategic Simplicity is a collection of content provided for free by experts, many of whom worked with one another in a variety of jobs.

Rose Gottemoeller needs no introduction to regular listeners, however, it’s possible you didn’t see the release of her recent book on U.S.-Russia relations titled “Security Through Cooperation: Space, Nuclear Weapons, and US-Russia Relations After the Cold War.” During the podcast, we cover the post-Cold War U.S.-Russia relationship, from hopeful early days to the negative trajectory that marks the relationship for the past 15-20 years. Rose also points to what changes may need to happen for the relationship to return to a friendlier footing.You can find her bio here: https://cisac.fsi.stanford.edu/people/rose-gottemoellerAnd the page for her book here: https://www.sup.org/books/politics/security-through-cooperationWe also mentioned Bill Browder’s book during the podcast, which you can find here. It is an important read for someone wishing to understand modern Russia.Intro/outro music licensed by Soundstripe: “The Iron Curtain” by Wicked Cinema.Recording and edits through Riverside.fm.Strategic Simplicity is a collection of content provided for free by experts, many of whom worked with one another in a variety of jobs.

We set out to discuss recent articles in the Orbis Journal of World Affairs by Lowell - a return guest on the Strategic Simplicity Podcast - and Austin Long. Each author raised different aspects of nuclear competition in their articles, with Lowell focusing on the possible “nuclear relationships” the United States may choose with Russia and China, and the impacts that may have nuclear forces and arms control policy. Austin’s article - shockingly - reviews Cold War superpower relations with a particular focus on the role technology played in the o.g. arms competition, and the new technologies that may play a role in the competition of today and tomorrow. We strayed into a wide ranging conversation about all things that are relevant to nuclear policy and arms control - grand strategy, bureaucratic prioritization, nuclear strategy - and Vipin barely got a word in edge-wise. Both authors end the podcast with the questions that preoccupy their minds after going through the writing process - hopefully a useful takeaway from students and young professionals subscribing to this pod.Lowell’s article Orbis.Austin’s as well.Strategic Simplicity is a collection of content provided for free by experts, many of whom worked with one another in a variety of jobs.

We take our conversation about ‘role’ and ‘reliance’ into a second podcast, where we share our opinions of Tyler Bowen’s May 15, 2026 article in War on the Rocks: “Restrain and Hedge: A New U.S. Nuclear Strategy for a Two-Peer World.” In his article, Tyler Argues for a U.S. strategy that deemphasizes damage limitation as an embrace of “nuclear restraint.” Instead, he proposes that the United States pursues an arms control framework with both Russia and China while improving the U.S. nuclear enterprise and defense industrial base to prepare the United States for an environment where arms control endeavors fail a trilateral arms race is unavoidable.

We rarely take liberties as co-hosts to talk about arcane and didactic international security subject matter. Or perhaps we do that every episode. At least we usually don’t spend a lot of time engaging in definitional combat. Austin, Matthew, Vipin, and I tried to do a little bit of that in Part I of this episode where we discussed the role of nuclear weapons vs. reliance on (or, because of Vipin, “salience of”) nuclear weapons. We asked ourselves whether these terms matter anymore, and if their relevance is fading, what does that say about the state of nuclear policy debates in DC and worldwide, the expert community’s interest in how nuclear weapons fit in national security strategy, and the level of understanding among international counterparts debating nuclear policy at fora such as the NPT Review Conference?Some authors who’ve touched on the subject in recent years - largely in advance of nuclear posture reviews or policy processes - and i’m sure there are many more, but not many recently:Brad Roberts: “On Adapting Nuclear Deterrence to Reduce Nuclear Risk.” 2020.Sophia Becker and Elisabeth Suh: “How Biden’s Plan to Limit the Role of Nuclear Weapons Challenges NATO.” 2021Matt Costlow: “A Net Assessment of ‘No First Use’ and ‘Sole Purpose’ Nuclear Policies.” 2021.Adam Mount: “ The Biden Nuclear Posture Review: Obstacles to Reducing Reliance on Nuclear Weapons.“ 2022.Amy Woolf (formerly of CRS): “U.S. Nuclear Weapons Policy: Considering “No First Use.” Updated 2022.

The gang got together this weekend to talk about a new Stimson Center report, “Why Strategic Superiority (Still) Doesn’t Matter: Nuclear Crises and the Failure of Theory.“ The new report by Chris Preble, Senior Fellow and Director of the Reimagining US Grand Strategy program at the Stimson Center, and Lucas Ruiz, a recent Herbert Scoville Jr. Peace Fellow in the same program, analyzes the role nuclear weapons played in four crises: the Cuban Missile Crisis, the Sino-Soviet Border Conflict of 1969, the 1973 Arab-Israeli (Yom Kippur) War, and the Kargil Crisis. Based on our read, the report functions as a rebuttal to a 2018 book by Georgetown professor Matthew Kroenig, titled "The Logic of American Nuclear Strategy: Why Strategic Superiority Matters."The report advocates for “sufficiency” as a north star for U.S. nuclear force planning - a secure second strike capability - rather than “superiority” is suggests has dominated U.S. nuclear thinking to date. The authors note that superiority “does not enhance security; it signals offensive intent, invites countermeasures, and erodes the stability that deterrence is supposed to protect.”We talk about the report's analysis of a few of these crises, the consequences of a "sufficiency" approach, especially for extended deterrence and nonproliferation, how non-nuclear weapons states may react to these obscure nuclear strategy debates in Washington, and discuss the connection between nuclear posture and arms control. Take a listen, and read the report below:https://www.stimson.org/2026/why-strategic-superiority-still-doesnt-matter/#elementor-toc__heading-anchor-0and here's a link to Kroenig's book too:https://academic.oup.com/book/5898 This is a public episode.

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.

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.Background reading:Frank Miller and Eric Edelman, “No New START: Renewing the U.S.-Russian Deal Won’t Solve Today’s Nuclear Dilemmas.” Foreign Affairs.Frank Miller and Eric Edelman, “Time to End the Last U.S.-Russia Nuclear Treaty.” The Bulwark.Rebeccah Heinrichs, “New Start and Trump’s Nuclear Test.” WSJ.Strategic Simplicity is a collection of content provided for free by experts, many of whom worked with one another in a variety of jobs.
