Podcast Summary: Face the Nation with Margaret Brennan – Extended Interview: Rafael Grossi
Episode Date: March 23, 2026

Overview

In this extended interview, Margaret Brennan speaks with Rafael Grossi, Director General of the International Atomic Energy Agency (IAEA), in his first U.S. network TV interview since the outbreak of war in Iran. The conversation delves into the ramifications of recent military actions on Iran’s nuclear program, the limitations of military solutions, challenges facing nuclear inspections, and the future of diplomatic negotiations. Grossi provides a detailed, technical, and candid view of the status of Iran's nuclear capabilities, the IAEA's role, and what's needed moving forward.

Key Discussion Points & Insights

1. Impact of Military Action on Iran’s Nuclear Program

• Destruction, but Not Elimination (01:37):
  • Grossi acknowledges significant damage from recent military campaigns to Iranian nuclear facilities (Fordo, Natanz, Isfahan). However, he emphasizes this rollback is relative and incomplete.
  • Quote: “There has been a lot of impact on the program. One cannot deny that this has really rolled back the program considerably… But...once the military effort comes to an end we will still inherit a number of major issues.” (03:14)
• Survival of Critical Enriched Material:
  • Despite attacks, Iran still possesses inventory of uranium enriched up to 60%, close to weapons-grade.
  • Uncertainty remains about the exact state of facilities, to be clarified only after IAEA inspectors return.

2. Nature of Iran’s Nuclear Program & IAEA’s Position

• No Clear Evidence of a Systematic Weapons Program (04:38):
  • Grossi reiterates the IAEA found no evidence of a systematic weapons program like the early 2000s "Amad plan," but points to many concerning actions and unanswered questions, especially since 2019.
  • Quote: “We are not analysts or people having opinions. We are the IAEA. So whenever we say something, it has to be based on actual inspection.” (04:39)
• Access Denials and Unanswered Questions:
  • Lack of full access and unexplained uranium found at undeclared sites hindered clear reporting.
  • Quote: “I have to say that I'm no longer able to say that everything is in order because you were finding uranium in places it wasn't supposed to be.” (06:53)

3. Limits of Military Solutions

• Knowledge and Capability Can’t Be Bombed Away (08:51):
  • Iran’s technical knowledge is permanent; dismantling facilities doesn’t destroy the capacity to rebuild.
  • Quote (Margaret): “You can't bomb away the knowledge. So that capability will exist after coming.”
  • Quote (Grossi): “Exactly. And it was very sophisticated…” (08:55)
• Centifuge and Industrial Know-How:
  • Iran’s advancements since the JCPOA: “...now Iran has the most sophisticated, fast and efficient machine that exists... This is why what I say is that we still need to find a framework...” (08:55–09:56)
• Summary Insight: Any war short of nuclear conflict can only delay, not eliminate, Iran’s nuclear potential.

4. Challenges & Options for Securing Enriched Material

• Difficulty of Securing/Removing Enriched Uranium (10:33):
  • Handling cylinders of gaseous uranium hexafluoride is hazardous and logistically complex.
  • There may also be decoys and hidden stockpiles, further confounding military efforts.
  • Quote: “It would be a very challenging operation for sure...” (12:01)

5. Potential Diplomatic Pathways

• Pre-war Negotiations (13:29):
  • Oman mediated discussions just before bombing began, including potential "down-blending" or export of enriched uranium.
  • Quote (Margaret): “Was there really the possibility of a deal because it was just hours before the bombing began?” (13:30)
  • Quote (Grossi): “While there is a negotiation, there's always a possibility of an agreement... There was a discussion, but there was no agreement.” (13:41–13:49)
• Need for Continued Talks:
  • Grossi pressed for technical meetings even as military action loomed (14:01–15:13).
  • Quote: “I felt that that was my obligation. I was invited to provide my technical support.” (15:17)

6. The Tehran Research Reactor Debate

• Level of Enrichment and Medical Use (15:54–18:25):
  • 20% enrichment for research reactors is above what the JCPOA permitted.
  • Grossi is cautious, clarifies IAEA's neutral, technical role—not judging intentions.
  • Quote: “What we discuss is technical capabilities and what technical capabilities may allow you to do or not. Intentions are legitimately discussed at the national level. My job is a different job...” (17:47)
• Honesty vs. Verification:
  • Calls for full access: “If you don't have anything to hide, show us.” (19:24–20:15)

7. Current Assessment & Need for Transparency

• State of Iran’s Program Post-Strikes (20:15–21:34):
  • US intelligence claims Iran's enrichment program was "obliterated"; Grossi generally concurs there's no evidence of activity during war, but stresses Iran retains knowledge and industrial capacity.
  • Quote: “We haven't seen. But as I was saying, a lot has survived. They have the capabilities, they have the knowledge, they have the industrial ability to do that. This is why we need to go back to a negotiating table.” (20:52)
• Credibility in Future Negotiations:
  • Calls for U.S. and Iran leadership, not regional talks, for a durable solution. The IAEA can facilitate but not lead the diplomatic process (21:47–22:35).

8. Undeclared Facilities & Inspectors’ Access

• Majority of Material in Isfahan (22:53):
  • “Well, it's a little bit more, but the majority of the material is there...” (22:53)
• Call to Inspect New/Never-Visited Sites (23:11–23:58):
  • Recent announcements of new facilities need urgent inspection—last attempt interrupted by military action.

9. Reflections on Military vs. Diplomatic Solutions

• Final Emphasis on Diplomacy (24:25):
  • Ultimately, only diplomatic engagement and on-the-ground inspections can address the fundamental issues.
  • Quote: “I don't know whether [President Trump] would endorse this or not, but he has said also that of course diplomacy is the preferred option. I think that is encouraging...” (24:25)

Notable Quotes & Memorable Moments

Conclusion:
Rafael Grossi offers a sobering analysis: While military action can significantly hinder Iran’s nuclear program, it cannot eliminate the underlying capabilities, knowledge, or ambition. Only through transparent inspections and sustained diplomatic engagement can both the international community and Iran ensure nonproliferation. The IAEA stands ready to facilitate this process, pending political will and security on the ground.
