• What Happened: President Trump issued a 48-hour ultimatum Saturday warning Iran to open the Strait of Hormuz or make a deal before "all Hell will reign down." Sen. Lindsey Graham confirmed after speaking with Trump that he is "completely convinced" the president will use "overwhelming military force" if Iran refuses. The deadline is Monday, April 6.
  • Why It Matters: The Strait of Hormuz closure has triggered what the IEA calls the worst energy disruption since the 1970s, with 10 million barrels per day lost and oil prices up 60% since the war began. Iran's military called Trump's post "helpless and stupid" and warned "the gates of hell will open for you." Houthi proxies are now threatening to close Bab el-Mandeb as well.
  • Bottom Line: Iran has Trump's ultimatum, a rescued colonel, a Tuesday deadline, and a president who just told the Wall Street Journal he will destroy every power plant and every bridge if they don't open the strait. The clock is running.

On Saturday morning President Trump posted three sentences on Truth Social that the entire world read.

"Remember when I gave Iran ten days to MAKE A DEAL or OPEN UP THE HORMUZ STRAIT. Time is running out — 48 hours before all Hell will reign down on them. Glory be to GOD!"

It is Day 36 of Operation Epic Fury. The Strait of Hormuz remains closed to American and allied shipping. Ten million barrels of oil per day are off global markets. Oil prices have surged 60% since the war began. The International Energy Agency is calling it the worst energy disruption since the 1970s and warning April will be worse than March. And Trump is done waiting.

The 48-hour deadline traces back to a March 26 extension Trump granted after what he described as "very good and productive conversations" with Iranian officials. That pause was supposed to produce a deal. It did not. Trump pushed the deadline to April 6. That deadline is now today.

Sen. Lindsey Graham spoke with Trump Saturday and made clear what the president told him. "After speaking with President Trump, I am completely convinced that he will use overwhelming military force against the regime if they continue to impede the Strait of Hormuz and refuse a diplomatic solution," Graham posted on X. "A massive military operation awaits Iran if they choose poorly. If it's not clear to Iran and others by now that President Trump means what he says, I don't know when it will ever be."

Trump told the Wall Street Journal that if Iran does not act by Tuesday evening, "they won't have any power plants and they won't have any bridges standing."

Iran's response was defiant. Gen. Ali Abdollahi Aliabadi of the IRGC's Khatam al-Anbiya Central Headquarters dismissed Trump's post as "a helpless, nervous, unbalanced and stupid action," adding with religious symmetry: "The simple meaning of this message is that the gates of hell will open for you."

Iranian Foreign Minister Abbas Araghchi claimed Tehran's position was being "misrepresented by U.S. media" and insisted Iran had "never refused to go to Islamabad," while calling for a "conclusive and lasting END to the illegal war that is imposed on us." His statement contained no meaningful concession.

Behind the scenes, diplomacy is grinding on multiple tracks. VP Vance and Iran's parliament speaker Mohammad Bagher Ghalibaf have been leading indirect negotiations mediated by Pakistani military chief Field Marshal Asim Munir. Oman's foreign ministry said it met with Iranian officials Saturday to discuss "possible options for ensuring the smooth flow of transit through the Strait of Hormuz." Pakistan, Turkey, and Egypt are all working to bridge the gap between the two sides.

The stakes extend far beyond Hormuz. Iranian parliament speaker Ghalibaf appeared Friday to threaten the Bab el-Mandeb Strait, posting pointed questions about oil, LNG, wheat, rice, and fertilizer flows through the waterway. Iran-backed Houthi deputy information minister Mohammed Mansour made it explicit, warning that closing Bab el-Mandeb "is a Yemeni option that can be implemented should the aggression against Iran escalate savagely, or if any Gulf state becomes directly involved." If Bab el-Mandeb closes alongside Hormuz, the global energy catastrophe deepens dramatically.

The UAE reported intercepting 23 ballistic missiles and 56 drones from Iran on Saturday alone. Since the war began, UAE air defenses have engaged nearly 500 ballistic missiles, 23 cruise missiles, and more than 2,100 drones. At least two Emirati service members and 11 civilians have been killed. Over 215 people have been injured.

The Easter rescue of the wounded F-15 colonel from inside Iran's mountains provided a powerful backdrop to Trump's ultimatum. He brought his man home. Now he wants the strait open. Two things Iran did not expect to face on the same morning.

Monday is the deadline. Tuesday, Trump told the Journal, is when every power plant and every bridge goes dark.

Iran has been warned.
