US downplays Iran deal text, cites back-channel commitments

US officials describe the circulated text of the Iran agreement as vague and mainly a political framework meant to set the stage for highly technical talks, noting it does not reflect critical back-channel commitments Iran has offered (such as sanctions relief and unfreezing funds). They argue substantive details will come through ongoing negotiations, while critics push for full disclosure of the framework. The document outlines some financial relief and oil sales but lacks specifics on uranium destruction. A 60-day window of in-person talks is planned, with a signing ceremony in Switzerland as negotiators push toward a final deal.
