Attacks on multiple commercial ships in the waters around Iran on Wednesday increased global energy concerns, pushed nations to unleash strategic oil reserves and sparked fresh critiques of the Trump administration’s readiness for a war it started.

As Trump administration and U.S. military officials continued to claim increasing success and advantage in the conflict, leaders around the world scrambled to respond to the latest attacks and the International Energy Agency’s call for the largest ever release of strategic oil reserves by its members to help stem energy price spikes.

In an address Wednesday morning, IEA Executive Director Fatih Birol said energy shipments through the Strait of Hormuz had “all but stopped” amid the conflict, driving massive global competition for oil and gas in wealthier countries and fuel rationing in poorer nations.

He said the IEA’s 32 member nations have brought a “sense of urgency and solidarity” to recent discussions on the matter, and had unanimously agreed to “launch the largest ever release of emergency oil stocks in our agency’s history,” making 400 million barrels of oil available.

However, he said the most needed change is the “resumption of traffic through the Strait of Hormuz.”

Several countries, including Germany, Austria and Japan, had already confirmed their plans to release reserves.

The White House did not immediately respond to a request for comment on any U.S. plans to release its strategic reserves, or how much would be released. The U.S. is an IEA member.

However, U.S. Interior Secretary Doug Burgum backed the idea of releasing oil reserves in a Fox News interview.

“Certainly these are the kinds of moments that these reserves are used for, because what we have here is not a shortage of energy in the world; we’ve got a transit problem, which is temporary,” Burgum said. “When you have a temporary transit problem that we’re resolving militarily and diplomatically — which we can resolve and will resolve — this is the perfect time to think about releasing some of those, to take some pressure off of the global price.”

Burgum said that while Iran is “holding the entire world hostage economically by threatening to close the strait,” President Trump has made the consequences of such actions “very clear,” and “there’s a lot of options between ourselves and our allies in the region, including our Arab friends in the region, to make sure that those straits keep open and that energy keeps flowing for the global economy.”

While some tankers believed linked to Iran were still getting through the Strait of Hormuz, which under normal circumstances carries 20% of the world’s oil and natural gas, Iranian officials threatened attacks on other vessels — saying they would not allow “even a single liter of oil” tied to the U.S., Israel or their allies through the channel, which connects to the Persian Gulf.

Trump has repeatedly claimed that the U.S. and its powerful Navy would support commercial vessels and ensure the strait remains open to oil shipments, but that has not been the case.

The United Kingdom Maritime Trade Operations center, run by the British military, has reported at least three ships struck in the region Wednesday — including ships off the United Arab Emirates and a cargo ship that was struck by a projectile in the strait just north of Oman, setting it ablaze.

The Trump administration and the U.S. military, meanwhile, have been pushing out messaging about wiping out Iran’s ability to plant mines in the strait — posting dramatic videos of major strikes on tiny boats on small docks.

Adm. Brad Cooper, the leader of U.S. Central Command, said in a video posted to X on Wednesday morning that “in short, U.S. forces continue delivering devastating combat power against the Iranian regime.”

“I’ve said this before, but it bears repeating: U.S. combat power is building, Iranian combat power is declining,” he said.

The U.S. has struck more than 60 Iranian ships, and just “took out the last of four Soleimani-class warships,” he said. “That’s an entire class of Iranian ships now out of the fight.”

Cooper said Iranian ballistic missile and drone attacks have “dropped drastically” since the start of the war, though “it’s worth pointing out that Iranian forces continue to target innocent civilians in gulf countries, while hiding behind their own people as they launch attacks from highly populated cities in Iran.”

He also addressed the attacks on commercial shipping in the region directly, saying that “for years, the Iranian regime has threatened commercial shipping and U.S. forces in international waters,” and that the U.S. military’s “mission is to end their ability to project power and harass shipping in the Strait of Hormuz.”

Other U.S. leaders called the U.S. war plan — and specifically its approach to protecting the Strait of Hormuz — into question.

In a series of posts to X late Tuesday, which he said followed a two-hour classified briefing on the war, Sen. Chris Murphy (D-Conn.) slammed the administration’s plans as “incoherent and incomplete.”

Murphy wrote that the administration’s goals for the war seemed to be focused primarily on “destroying lots of missiles and boats and drone factories,” and without a clear plan for what to do when Iran — still led by “a hardline regime” — begins rebuilding that infrastructure, other than to continue bombing them. “Which is, of course, endless war,” he wrote.

Murphy also specifically criticized the administration’s plan for the Strait of Hormuz — which he said simply doesn’t exist.

“And on the Strait of Hormuz, they had NO PLAN,” he wrote. “I can’t go into more detail about how Iran gums up the Strait, but suffice it say, right now, they don’t know how to get it safely back open. Which is unforgiveable, because this part of the disaster was 100% foreseeable.”
