Failure of the American and United Arab Emirates oil activity in the Strait of Hormuz The HFI Institute announced the failure of the operation known as the "super cluster" planned by the United Arab Emirates and the participation of the United States in transferring oil through the Strait of Hormuz. According to the report of this institute, the passage of oil through the Strait of Hormuz has reached almost zero following the escalation of Iran's confrontation with the violators in the last month. Operation Supercluster is an operation that removes oil from the Persian Gulf in a series of operations, including crossing the strait by ferry and ship-to-ship, and was planned by the United Arab Emirates.
