Washington. US President Donald Trump started the fourth week of his war against Iran by offering the world some guarded optimism that the United States could soon be winding operations down, a claim that markets cheered but Iranian officials dismissed as a ploy to buy time for a conflict that is causing economic pain around the globe.

In a social media message timed before markets opened, Trump said he was putting off for five days plans he announced over the weekend to bomb Iran's power plants unless Tehran opened the Strait of Hormuz by Monday evening. The critical passageway for some 20% of the world's crude has been effectively shuttered during the war, sending oil and gas prices soaring.

He decided to hold back on targeting Iran's critical infrastructure, Trump explained, because his envoys, son-in-law Jared Kushner and Steve Witkoff, had “very good” talks over the weekend with unnamed “respected” Iranian officials on ending hostilities.

The president made no mention of Iran's vow that vital infrastructure across the Gulf region — including energy and desalination facilities critical for drinking water — would be considered legitimate targets and “irreversibly destroyed" if Trump acted on his threat. The back-and-forth drove a steep selloff in Asian markets as the clock ran down on Trump’s ultimatum.

“All I’m saying is we are in the throes of a real possibility of making a deal,” Trump said during an extended exchange with reporters before boarding Air Force One on Monday morning to make his way from his home in Florida to an event in Memphis, Tennessee. “And I think, if I were a betting man I’d bet for it. But again, I’m not guaranteeing anything.”

Before the president's plane had landed in Tennessee, less than two hours later, Iran refuted that there had been any high-level communications with the White House and dismissed Trump's rhetoric as a thinly veiled attempt to manipulate jittery global markets.

“No negotiations have been held with the US," Mohammad Bagher Qalibaf, the speaker of Iran's parliament, posted on X. "And fakenews is used to manipulate the financial and oil markets and escape the quagmire in which the US and Israel are trapped.”

The Iranian Foreign Ministry also said Trump’s statement was nothing more than an effort “to reduce energy prices and to buy time for implementing his military plans.”

Trump's Key Objectives in the War Have Not Yet Been Achieved
If Trump were to end the war now, he would be walking away from the fight at a moment when he still hasn't fully achieved his stated objectives, some regional analysts have noted.

Over the course of the past few weeks, Trump has offered shifting reasons for launching the war as Democrats accuse him of needlessly shaking the global economy and polls at home show that Americans are divided along party lines about the conflict.

But the president has settled on a list of goals he has said must be achieved, including degrading Iran’s missile capability, destroying its defense industrial base, eliminating the Iranian navy, preventing Iran from ever acquiring nuclear weapons, and securing the Strait of Hormuz.

The US and Israeli air bombardment has made progress on some of those goals. But analysts say Trump would strain credulity if he were to claim, at this point, that he made good on achieving his aims — particularly definitively ending Iran's ability to build a nuclear bomb.

The US and nuclear watchdogs believe some 970 pounds of highly enriched uranium remains buried beneath rubble at three key Iranian nuclear sites that were badly damaged by a limited U.S. military operation last June during the 12-day Israel-Iran war.

Trump said on Monday the US would retrieve Iran’s enriched uranium as part of a potential agreement with the Islamic Republic. But he offered no details on how, beyond saying the US military will “take it ourselves.”

“Trump’s war choice has not accomplished his military goals," Aaron David Miller, a former State Department Mideast negotiator who is now a senior fellow at the Carnegie Endowment for International Peace, said on X. Miller noted that Iran is still able to attack Gulf allies and effectively control the Strait of Hormuz. “No nukes; no enrichment, good luck with that. A singularly incompetent use of America’s power.”

More US Troops Are Still on the Way
Indeed, Trump on Monday sought to leave plenty of space for him to take another abrupt turn, even as he spotlighted the positive reaction in energy markets to his early morning social media post about the talks being underway.

“The price of oil will drop like a rock as soon as a deal is done. I guess it already is today,” Trump said. “Now we have a very serious chance of making a deal. That doesn’t guarantee anything. I’m not guaranteeing anything. I’m not going to come out here in a week or two weeks, and have you all say, ‘Oh, you said...' — I didn’t say anything."

Trump last week ordered additional US troops to the region as the U.S. administration weighs possible action to take control of the Strait of Hormuz to allow for the safe passage of tankers bringing oil from the oil-rich Gulf nations to Asia.

The U.S. moved last week to deploy three more amphibious assault ships and roughly 2,500 additional Marines to the Middle East, The Associated Press and other news outlets reported. The move came days after the US redirected another group of amphibious assault ships carrying another 2,500 Marines from the Pacific to the Middle East. The Marines will join more than 50,000 US troops already in the region.

Trump has said he has no plans to send ground forces into Iran but also has asserted that he retains all options. It is expected to take weeks for those Marines to arrive in the Mideast.

“We are witnessing how a conflict that began over politics and security is moving to be defined by energy and economics," said Behnam Ben Taleblu, senior director of the Foundation for Defense of Democracies, a hawkish Washington think tank. “It’s hard to ignore the logic inherent in the president’s own commentary, which both calms markets but also buys time for Marines to arrive.”
