The United States has committed to striking Iranian military infrastructure if Iran threatens shipping through the Strait of Hormuz, the narrow waterway that carries roughly 20% of the world’s oil trade.

Operation Epic Fury and the 48-hour ultimatum

US forces launched Operation Epic Fury on February 28, 2026, targeting Iranian naval and military sites in what marked a significant escalation of hostilities. The operation was conducted alongside Israeli military assets, making it a coordinated campaign against Iranian infrastructure.

Iran responded by asserting control over the Strait of Hormuz and threatening attacks on vessels transiting the waterway.

President Trump raised the stakes further on March 22, 2026, threatening to “obliterate” Iranian power plants unless shipping routes were reopened within 48 hours.
