U.S. President Donald Trump said on the 12th (local time) that “the U.S. Navy, the world’s most powerful, will immediately begin blocking all vessels entering or leaving the Strait of Hormuz.” The comment came after talks with Iran collapsed and underscored an administration plan to assert control over the strait and choke off Iran’s oil exports.

Trump wrote on Truth Social: “I ordered our Navy to find and intercept in international waters any vessel that has paid transit fees to Iran. Anyone who has paid illegal transit fees will not be able to sail safely in international waters.”

He added, “We will begin removing the mines Iran has planted in the strait,” and warned, “Anyone Iranian who fires on us, or anyone who fires on peaceful vessels, will be sent to hell.”

Trump also said, “One day we will reach a stage that allows the entry and exit of all ships, but Iran has blocked that by saying — a line only they know the truth of — that ‘there might be mines somewhere.’”

He characterized the tactic as extortion against the international community and stressed that world leaders, especially the United States, will not be extorted.

On the talks that ended with no deal, he said, “Negotiations went well and we agreed on most issues, but the one truly important issue — the nuclear issue — was not resolved.”
