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. However, if you would like to see more text…
