Trump’s Final Ultimatum to Iran Over the Strait of Hormuz

President Donald Trump has issued an ultimatum to Iran to reopen the Strait of Hormuz, threatening to launch military strikes against critical Iranian infrastructure if the shipping route remains blocked.

In a social media post published on April 5, 2026, the U.S. President stated that the Iranian regime has until Tuesday, April 7, 2026, to meet his demands. The Strait of Hormuz is a vital oil shipping route that typically carries approximately one-fifth of global oil and liquefied natural gas.

Trump warned that failure to reopen the route would result in attacks on Iranian power plants and bridges. He described the upcoming deadline as Power Plant Day and Bridge Day, all wrapped up in one, in Iran.

Open the F—— Strait, you crazy bastards, or you’ll be living in Hell – JUST WATCH! Praise be to Allah.

Timeline of Ultimatums and Escalation

The current tension follows a series of deadlines set by the U.S. Administration. On March 21, 2026, President Trump first gave Iran 48 hours to reopen the shipping route. Later, on March 26, 2026, he established a 10-day deadline for the reopening of the Strait.

The blockade of the Strait of Hormuz began after the United States and Israel initiated attacks on Iran on February 28, 2026. Since that date, maritime traffic through the route has largely ground to a halt.

The April 5 post also served as a platform for the president to applaud the U.S. Military for the rescue of a second airman whose fighter jet had been shot down over Iran.

International and Regional Reactions

Iranian officials have condemned the threats, with the Iranian mission to the United Nations stating that the U.S. President is threatening infrastructure essential for civilian survival. Iranian officials have promised to retaliate against any attacks on their infrastructure.

Mohammad Baqer Qalibaf, the Speaker of the Iranian Parliament, criticized the moves as reckless and alleged that Israeli Prime Minister Benjamin Netanyahu was misleading the U.S. President.

Your reckless moves are dragging the United States into a living HELL for every single family, and our whole region is going to burn because you insist on following Netanyahu’s commands. Make no mistake: You won’t gain anything through war crimes.

Economic and Diplomatic Context

The threats have had an immediate impact on global markets, with crude oil prices jumping in early trading on April 5, 2026, following the warning of potential strikes on April 7.

Despite the public threats, President Trump told Fox News on April 5, 2026, that Iran is currently negotiating with the United States. He expressed belief that a deal could be reached before the Tuesday deadline.

The regional conflict has extended beyond the Strait of Hormuz. Reports indicate that universities have been hit as the U.S. And Israel ramp up attacks on Iranian infrastructure, and power and water plants in Kuwait have been damaged by Iranian attacks on Gulf states.
