Rubio: 'Pretty Solid Thing on the Table' — US-Iran MoU Framework Provides 60-Day Window to Finalize; Nuclear Enrichment Details NOT Included in Initial MoU — Day 87

US Secretary of State Marco Rubio on May 25, 2026 (Day 87) confirmed there is 'a pretty solid thing on the table' in the US-Iran negotiations — a notably more definitive characterization than his May 24 'significant progress' language. Rubio clarified that negotiations are 'still a work in progress' but that the framework being discussed would commit Iran to never possessing a nuclear weapon and to surrendering its highly enriched uranium stockpile. The emerging MoU structure, per CNN's May 25 live reporting, would provide parties 60 days to reach final deal points, rather than constituting a comprehensive final agreement — meaning the MoU would not itself resolve all issues but would create a structured negotiating window under a ceasefire. Critically, nuclear enrichment details — the most divisive issue between Washington and Tehran — are NOT included in the initial MoU text, to be addressed in the 60-day follow-on negotiation. Former CIA Director David Petraeus said on CNBC on Day 87 that Iran is 'in the process of blinking' over the Strait of Hormuz, citing Iran's restoration of access to 30 of its 33 missile sites along the strait as evidence of Iranian concessions — though Iran continued to frame the moves as 'navigational service fee' structures rather than free passage. Oil prices continued to fall on Day 87 deal momentum: CNN described prices as 'plunging' as the US and Iran edge closer. Rubio's evolution — from 'slight progress' (Day 84) to 'significant progress' (Day 86) to 'pretty solid thing on the table' (Day 87) — represents the most positive US diplomatic language since the conflict began.
