U.S. President Donald Trump has threatened to destroy Iran’s power plants if Tehran does not reopen the Strait of Hormuz within 48 hours. The ultimatum, issued late on March 21, 2026, demands that Iran allow free passage through the key global energy corridor or face severe consequences.

In response, Iran dismissed the threat and issued a counter-warning. The Iranian military, citing Fars News Agency, stated that any attack on Iran’s energy or power infrastructure would trigger retaliatory strikes on all U.S. and allied energy, information technology, and desalination facilities across the region. Tehran reaffirmed its earlier warnings that any violation of its infrastructure would be met with a broad regional response.

The exchange of threats has heightened tensions in the Gulf, where the Strait of Hormuz remains a critical route for global oil shipments. The situation underscores the fragility of regional stability and the potential for escalation if diplomatic channels fail to ease the standoff.
