Over the weekend Trump repeated a pattern that has emerged throughout the past five months: announcing plans for “massive attacks” on Iran, only to cancel them at the last minute. Iran’s Foreign Ministry spokesman Esmail Baghaei rejected the claim, saying no negotiations with the United States were taking place and no meetings were scheduled. Iran had no plans to host foreign delegations or send negotiators abroad in the coming days, he said. The only talks under way, he said, were discussions with Oman over management of the Strait of Hormuz. So far the United States has failed to compel Iran to relinquish its grip on the waterway, sending global oil prices higher and pushing up politically sensitive gasoline prices in the United States.
