President Donald Trump said the ceasefire between the United States and Iran is still holding, even as both sides exchanged fire in the Strait of Hormuz in what appears to be the most direct military confrontation between the two countries in years.

U.S. Central Command said Iran fired missiles and launched drones at three American destroyers in the strait, describing the attacks as unprovoked. U.S. forces responded with strikes on Iranian military facilities and drone launch sites inside Iran. Iran disputes the sequence entirely, saying the United States fired first and that its own strikes were defensive.

Why the Strait of Hormuz Matters

The Strait of Hormuz is the narrow waterway between Iran and Oman through which roughly 20 percent of the world's oil supply passes. Any sustained military activity there puts global energy markets on edge. Tanker operators, insurers, and commodity traders treat the strait as one of the highest-risk chokepoints on earth, and even brief disruptions can push oil prices sharply higher.

The fact that Iran targeted U.S. naval destroyers — warships, not commercial vessels — marks a significant escalation in both scale and intent compared with past episodes of regional tension. Strikes on American military assets raise the stakes well beyond typical shipping-lane friction.

What the Ceasefire Claim Means

Trump's insistence that the ceasefire remains in effect is notable precisely because both sides just exchanged live fire. It suggests Washington is trying to hold open a diplomatic off-ramp while simultaneously authorizing military responses. Whether that framing holds depends on whether either side launches another round of strikes.

The conflicting accounts of who shot first are more than a he-said-she-said dispute. Under international law and each country's domestic political constraints, the question of who was the aggressor shapes justification for future action. Iran's framing of its strikes as defensive is designed to limit international pressure on Tehran; Washington's framing of its response as self-defense serves a similar purpose.

Watch for: any movement in oil futures when markets open, whether other Gulf states or NATO allies issue statements, and whether U.S. naval assets in the region are repositioned or reinforced in the coming hours.
