The fragile calm between the United States and Iran has collapsed. American forces struck targets across Iran in a new wave of attacks, hours before the United States moved to keep open the Strait of Hormuz, the narrow waterway through which a large share of the world's seaborne oil passes, as fears of an Iranian blockade grew.

The renewed fighting followed a short-lived cease-fire that had briefly eased tensions and, with them, global energy prices. That pause has now ended, and the exchange of strikes marked a return to open conflict. The truce had drawn a mixed reception, with some voices crediting it for a measurable drop in energy prices and others describing it as a "phony peace" that papered over unresolved disputes.

Inside the White House, President Trump convened a meeting in the Situation Room to weigh options for a larger campaign, including what officials characterized as a major offensive aimed at keeping the strait open. Trump had earlier floated a proposal to impose a 20 percent fee on shipments passing through the waterway, but he later backed away from that idea.

Among the targets Trump had raised were bridges and power plants inside Iran. Legal analysts noted that attacks on such civilian infrastructure could, depending on the circumstances, raise questions under the laws of armed conflict — a point that remains contested and unresolved.

The rhetoric on the Iranian side sharpened as well. One Iranian lawmaker proposed seizing a US military base and capturing American personnel to hold in Tehran, a suggestion that reflected the hardening mood in Iran's parliament even as questions persisted about who is directing the country's war strategy.

The economic reverberations were immediate. Oil prices climbed sharply after the latest strikes and amid the looming blockade, while stock markets turned mixed. The reversal was notable because inflation had eased in June, helped in part by falling energy prices during the brief truce. Renewed fighting now threatens to undo that progress and push gasoline prices higher.

Shippers, meanwhile, have begun adjusting. Some vessels are seeking alternate routes to move cargo, though there are limits to how much traffic can be diverted from a chokepoint of the strait's importance.

The conflict also poses a test for neighboring states. Iraq, which maintains ties to both Washington and Tehran, faces pressure to preserve a delicate balancing act as the escalation unfolds along its borders and across the wider Gulf.

For now, the central questions remain open. Whether the United States will proceed with a broader offensive, whether Iran can sustain a blockade, and how far the disruption to global energy markets will spread are all unresolved. So too is the possibility of a return to diplomacy. The recent cease-fire, however brief, showed that a pause remains achievable, and some officials and analysts continue to point toward a negotiated settlement as the path that would most quickly steady energy markets and lower the risk to shipping.
