DUBAI, United Arab Emirates (AP) — President Donald Trump lashed out Tuesday at allies who have been unwilling to do more to support the U.S. war effort against Iran, telling them to “go get your own oil” and declaring that securing the Strait of Hormuz is “not for us.”

The president estimated that the American military will be done attacking in two to three weeks and said the U.S. “will not have anything to do with” what happens in the strait that has been closed by the Islamic Republic. Instead, he told reporters that the responsibility for keeping the vital waterway open will rest with countries that rely on it.

There’s “no reason for us to do this,” Trump said after signing an executive order that seeks to restrict mail-in voting. “That’s not for us. That’ll be for France. That’ll be for whoever’s using the strait.”

In other developments, the closure of the strait sent average U.S. gas prices past $4 a gallon, and U.S. strikes hit the central city of Isfahan, sending a massive fireball into the sky. Tehran attacked a fully loaded Kuwaiti oil tanker in the Persian Gulf.

The attacks showed the intensity of the war more than a month after the U.S. and Israel launched it. The conflict has left more than 3,000 dead and caused major disruptions to the world’s supply of oil and natural gas, roiling global markets and pushing up the cost of many basic goods.

Trump, who has vacillated between insisting there is progress in diplomatic talks with Iran and threatening to widen the war, had earlier shared footage of the attack on Isfahan.

Iran’s stranglehold on the strait, the waterway leading out of the Persian Gulf through which a fifth of the world’s oil is transported during peacetime, has driven up global oil prices, as have Tehran’s attacks on regional energy infrastructure.

Spot prices of Brent crude, the international standard, hovered around $107 a barrel Tuesday, up more than 45% since the war started Feb. 28.

In a social media post, Trump directed blame at U.S. allies like the United Kingdom and France that have refused to enter a war with no clear endgame that they were not consulted on.

“You’ll have to start learning how to fight for yourself, the U.S.A. won’t be there to help you anymore, just like you weren’t there for us. Iran has been, essentially, decimated. The hard part is done. Go get your own oil!” Trump wrote.

He singled out France for not letting planes fly over French territory while taking military supplies to Israel.

France has allowed the U.S. Air Force to use the Istres base in southern France because it had guarantees that planes landing there would not be involved in carrying out strikes.

Spain, which has emerged as Europe’s loudest critic of the war, said Monday that it had closed its airspace for U.S. planes involved in the conflict.

Italy recently refused to allow U.S. military assets to use the Sigonella air base in Sicily for an operation linked to the offensive, an official with knowledge of the matter said, confirming a local press report. The official spoke on condition of anonymity because they were not authorized to speak publicly.

Italian Defense Minister Guido Crosetto wrote on X that Italy is still allowing the U.S. to use its bases, adding that there has been no cooling of relations between the two countries.

Journalist kidnapped

An American journalist was kidnapped Tuesday in Baghdad, and Iraqi security forces are pursuing her captors, Iraqi officials said. The journalist was identified as freelancer Shelly Kittleson by Al-Monitor, one of the news outlets she worked for.

A U.S. official blamed the Iranian-backed Iraqi militia Kataib Hezbollah.

Carrier deploys

The aircraft carrier USS George H. W. Bush deployed Tuesday from Norfolk, Virginia, and is slated to head to the Middle East, two U.S. officials said. They spoke on condition of anonymity to discuss sensitive military plans.

It would be the third aircraft carrier sent out to support the Iran war, along with the USS Gerald R. Ford, which is now undergoing repairs, and USS Abraham Lincoln, which arrived in the region in January.
