Looks more like a wish list than a MoU:
1) Unlikely, the blockade is the only leverage the US has, not giving way until the last vessel is out
2) Vessels are already slipping away from "Iran's control"
3) No way Oman joins this charade, they have 1Mnbpd to lose.
Iran state television says it has obtained a draft of the Washington-Tehran MoU. Main points for oil:
1) US will lift blockade and withdraw from Iran's waters.
2) Iran will allow commercial vessel transit via Strait of Hormuz to return to pre-war levels within 30 days.
3) Iran and Oman will administer a SoH mechanism.
(While the above has been mooted by others, it's the first time that Iranian state television, tightly controlled by the regime, reports about those points)
