Under the proposal, Iran would share oversight of the strategic waterway with Oman, which controls the opposite shore, and any payments by ships would be voluntary rather than mandatory, a source told Reuters. He said the United States would resume military action if negotiations failed. Iran rejected Trump’s account, saying it was not seeking to restart talks with Washington and that no direct negotiations were taking place. Iran effectively closed the strait to foreign shipping after U.S. and Israeli strikes on February 28. Iran responded by attacking U.S. bases in neighboring countries, killing American service members, and launching strikes on civilian infrastructure in Gulf states.
