WASHINGTON (AP) — President Donald Trump this week called for the United States and other oil-producing economies to pump more oil as crude prices remain volatile after the U.S. struck key Iranian nuclear facilities with a barrage of 30,000-pound bunker busting bombs and Tomahawk missiles.

Trump urged stepped-up production as the White House sharpened its warnings to Iran against closing the Strait of Hormuz, a vital oil and gas shipping lane, in retaliation for the U.S. strikes on Iran’s nuclear program.

“To the Department of Energy: DRILL, BABY, DRILL!!! And I mean NOW!!!” Trump posted on social media. He added, “EVERYONE, KEEP OIL PRICES DOWN. I’M WATCHING! YOU’RE PLAYING RIGHT INTO THE HANDS OF THE ENEMY. DON’T DO IT!”

Iran’s parliament has approved cutting off the Strait of Hormuz, a narrow shipping lane in the Persian Gulf that about 20 percent of global oil and gas passes through.

It’s now up to Iran’s national security council to decide whether to move forward with the idea, which could lead to a spike in the cost of goods and services worldwide.

White House press secretary Karoline Leavitt warned Tehran anew against closing the strait, saying, “the Iranian regime would be foolish to make that decision.”

Monday night Trump announced a possible ceasefire between Israel and Iran.

Many energy industry analysts are skeptical that Iran would go forward with a full closure of the strait, something that it has threatened to do in the past.

Iran would face the possibility of retaliation against its own shipments and the possibility that the move would upset China, the biggest purchaser of Iranian crude.

The United States and allies pressed Russia in the leadup to Moscow’s 2022 invasion of Ukraine with threats to its oil industry, and then followed through as many Western oil companies pulled out of the country and the United States and Europe imposed sanctions on Russian industry.

Iran is far less integrated into the global economy than Russia, which was reliant on European markets for its oil and gas exports and still went forward with the invasion despite U.S. warnings.

“There’s been a lot of suggestion as well that this isn’t something that is incredibly likely, and that’s generally attributed to economic interdependence, which I don’t want to suggest doesn’t matter. It absolutely does,” said Colby Connelly, a senior fellow at the Middle East Institute. “(I)f the 2020s have taught us anything so far, it’s that economic ties don’t always prevent conflict.”

Leavitt also appeared to play down Trump calling into question the future of Iran’s ruling theocracy.

“It’s not politically correct to use the term, ‘Regime Change,’ but if the current Iranian Regime is unable to MAKE IRAN GREAT AGAIN, why wouldn’t there be a Regime change???” Trump posted on social media. “MIGA!!!”

Leavitt said Trump’s “posture and our military posture has not changed.”

“The president was just simply raising a question that I think many people around the world are asking,” Leavitt said.
