US President Donald Trump has threatened to launch strikes on Iran’s power infrastructure if the Strait of Hormuz is not reopened within 48 hours, escalating tensions in an already volatile conflict.

In a message posted on social media, Trump said the United States would “hit and obliterate” Iranian power plants if Tehran failed to ensure the safe passage of ships through the strategic waterway.

Ultimatum over key oil route

“If Iran doesn’t FULLY OPEN, WITHOUT THREAT, the Strait of Hormuz, within 48 HOURS… the United States of America will hit and obliterate their various POWER PLANTS,” he wrote, adding that the largest facilities would be targeted first.

The Strait of Hormuz, located off Iran’s southern coast, is one of the world’s most important shipping routes, handling roughly a fifth of global oil supplies. Since the outbreak of the conflict, Iran has effectively blocked the passage, disrupting energy markets and raising global concerns over supply.

Mixed signals on military strategy

The warning comes amid conflicting messages from Washington about the direction of the military campaign. Just a day earlier, Trump suggested that US operations in the region could soon be scaled back, saying the country was “very close to meeting our objectives”.

Despite that statement, the latest threat indicates the administration is prepared to escalate further if key demands are not met. Trump also said the US would assist Gulf nations in securing the strait “if asked”, signalling a willingness to expand involvement in safeguarding maritime routes.

Strategic and economic stakes

The closure of the strait has had significant implications for global energy flows, with the route serving as a critical artery for oil exports from the Gulf. Any prolonged disruption risks further volatility in oil prices and broader economic consequences worldwide.

Iran has not publicly responded to the latest ultimatum, but the warning adds to mounting pressure as hostilities continue across the region.

Targeting civilian energy infrastructure is not a trivial threat. It’s the kind of tactic the international community has repeatedly condemned when used by other states.

When Putin struck Ukrainian power grids, world leaders called it an attack on civilian life and a violation of international humanitarian norms.

The same principle applies here: power plants are not military targets, they are lifelines for hospitals, water systems, and civilian survival.

If Trump were to carry out such strikes, the humanitarian fallout would be catastrophic.

Iran has already warned it would retaliate by targeting U.S. energy infrastructure, escalating the risk of a regional spiral.
