US President Donald Trump on Sunday announced a military blockade of the Strait of Hormuz as Vice President JD Vance’s negotiating team failed to gain the trust of their Iranian counterparts, who have been burned by the United States before and are loath to surrender sovereignty over their nuclear program.Trump announced in an early morning post on his Truth Social network that, “effective immediately,” the Strait of Hormuz—which was open before the president launched his illegal war of choice—would be closed to all shipping. Around 20% of the world’s oil passed through the waterway before the war.“At some point, we will reach an ‘ALL BEING ALLOWED TO GO IN, ALL BEING ALLOWED TO GO OUT’ basis, but Iran has not allowed that to happen by merely saying, ‘There may be a mine out there somewhere,’ that nobody knows about but them,” Trump wrote. “THIS IS WORLD EXTORTION, and Leaders of Countries, especially the United States of America, will never be extorted.”“I have also instructed our Navy to seek and interdict every vessel in International Waters that has paid a toll to Iran,” the president continued, referring to one of the concessions reportedly in the cease-fire agreement with Iran that he approved last week. “No one who pays an illegal toll will have safe passage on the high seas. We will also begin destroying the mines the Iranians laid in the Straits. Any Iranian who fires at us, or at peaceful vessels, will be BLOWN TO HELL!”“Iran will not be allowed to profit off this Illegal Act of EXTORTION,” Trump added. “They want money and, more importantly, they want Nuclear. Additionally and, at an appropriate moment, we are fully ‘LOCKED AND LOADED,’ and our Military will finish up the little that is left of Iran!”Responding to Trump’s post, Medea Benjamin, co-founder of the peace group CodePink, said on X: “So get this. Trump wants to open the Strait of Hormuz by closing the Strait of Hormuz. Blow up the world economy to punish Iran. Make sense?”Ryan Costello, policy director at the National Iranian American Council, also took to X, writing that “a blockade is an act of war, so Trump is announcing he will reenter the US into a war has been illegal under domestic and international law and has been disastrous for US interests, regional security, and the people of Iran.”Journalist Séamus Malekafzali said on X: “I have legitimately never heard of a more insane, designed-to-backfire policy under this administration; maybe ever. Not only attempting to blockade Iranian ships, but ANY ship that goes through the Strait of Hormuz by paying the toll.”While Trump and Secretary of State Marco Rubio attended a UFC match in Miami, Vance was left with the task of marathon negotiations with Iranian officials in Islamabad, Pakistan. It was the first direct high-level talks between the two countries since 1979.“We need to see an affirmative commitment that [Iran] will not seek a nuclear weapon, and they will not seek the tools that would enable them to quickly achieve a nuclear weapon,” Vance told reporters after the talks. “That is the core goal of the president of the United States, and that’s what we’ve tried to achieve through these negotiations.”Iran’s government was willing to make unprecedented concessions regarding its nuclear program up until the US and Israel began bombing the country on February 28. Every US administration since that of former President George W. Bush—including Trump’s—has concluded that Iran is not seeking to develop nuclear weapons.Iran gave its assurance that it would not build nukes in the Joint Comprehensive Plan of Action it signed in 2015 during the presidency of Barack Obama. Trump unilaterally scrapped the agreement, which was also called the Iran nuclear deal, during his first term despite—some say because of—Iran’s full compliance.Iranian Parliamentary ⁠Speaker Mohammad ⁠Baqer Ghalibaf blamed the US for the breakdown in talks.“My colleagues on the Iranian delegation Minaab168 raised forward-looking initiatives, but the opposing side ultimately failed to gain the trust of the Iranian delegation in this round of negotiations,” Ghalibaf said on X. The Iranian delegation was named after the town where 168 children and staff at an elementary school were massacred in a US cruise missile strike on the first day of the war.“Before the negotiations, I emphasized that we have the necessary good faith and will, but due to the experiences of the two previous wars, we have no trust in the opposing side,” Ghalibaf explained.Just hours before Trump announced his decision to bomb Iran in February, Omani Foreign Minister Badr bin Hamad Al Busaidi, the mediator of talks between the US and Iranian governments, said that a “peace deal is within our reach,” prompting Iranian officials and others to accuse the Americans of acting in bad faith.
