The ceasefire agreement between the US and Iran is off to a rocky start with Tehran tightening its grip on the Strait of Hormuz and accusing Israel of upending a deal the White House insists President Trump never agreed to.

The US, however, has not reattacked Iran as of Wednesday afternoon and announced formal talks in Pakistan this weekend to find a diplomatic solution.

Vice President JD Vance urged Iran not to let a “legitimate misunderstanding” over whether Lebanon was part of the ceasefire deal derail the fragile agreement. Israel continued to attack Hezbollah in Lebanon, which Iran took as a violation of the ceasefire, but the US disagrees.

“If Iran wants to let this negotiation fall apart in a conflict where they were getting hammered over Lebanon, which has nothing to do with them, and which the United States never once said was part of the cease-fire, that’s ultimately their choice,” Vance, who will lead US negotiations, said Wednesday. “We think that would be dumb but that’s their choice.”

The attempt to lower the temperature came after Iran’s parliament speaker on Wednesday said a cease-fire agreement to reopen the Strait of Hormuz and planned peace talks this weekend in Islamabad are “unreasonable” because the US “violated” a 10-point agreement.

“The deep historical distrust we hold toward the United States stems from its repeated violations of all forms of commitments — a pattern that has regrettably been repeated once again,” Mohammad-Bagher Ghalibaf said in a statement posted to X.

“As the President of the United States has clearly stated in his Truth, the Islamic Republic of Iran’s 10-Point Proposal is a ‘workable basis on which to negotiate’ and the main framework for these talks. However, 3 clauses of this proposal have been violated so far.”

The three points include Israeli strikes on Lebanon, denial of Iran’s right to uranium enrichment and an alleged drone incursion into Iranian airspace, which Ghalibaf claimed was “destroyed in the city of Lar in Fars Province.”

“In such situation, a bilateral ceasefire or negotiations is unreasonable.”

Minutes before his statement, White House Press Secretary Karoline Leavitt made clear that Trump trashed the initial 10-point plan ahead of the cease-fire agreement Tuesday night, insisting on a “more reasonable and entirely different and condensed plan to the president and his team.”

“The idea that President Trump would ever accept an Iranian wish list as a deal is completely absurd,” Leavitt said. “The president will only make a deal that serves in the best interest of United States of America.”

The rebuke puts in jeopardy planned talks between US and Iranian leaders in Islamabad, where Pakistani mediators plan to facilitate negotiations to end the war.

Ghalibaf’s statement came after Iran announced it would stop ships from passing through the waterway just hours after agreeing to reopen the Strait of Hormuz. In state-run media, Tehran blamed the breakdown on Israel striking Lebanon — despite Trump making clear Beirut was never part of the cease-fire agreement

“Due to Israeli strikes in #Lebanon, oil tankers will not be permitted to pass through the Strait of #Hormuz,” the Iranian embassy in Mumbai posted to X on Wednesday, citing Iran’s Fars News Agency.

But Trump on Wednesday told PBS News Hour that “everyone knows” Israel’s fight with Hezbollah in Lebanon is a “separate skirmish” not included in the cease-fire deal with Iran.

Hezbollah is an Iranian proxy group — one of several the US is demanding that Iran stop supporting.

Iran’s finger-pointing came as Tehran attempts to extract payment from ships that want to pass through the strait without coming under Iranian attack, despite promising to reopen the strait for two weeks. Tolls were reportedly as high as $2 million per ship.

Iran’s closure of the Strait of Hormuz is “completely unacceptable,” Leavitt told reporters Wednesday.

“Again, this is a case of what they’re saying publicly is different privately,” she said. “We have seen an uptick of traffic in the Strait today, and I will reiterate the president’s expectation and demand that the Strait is reopened immediately, quickly and safely.”

But earlier on Wednesday, Trump had said he was open to the controversial idea of tolling — if the US got a cut of the action.

Speaking to ABC News’ Jonathan Karl, Trump suggested the concept of allowing Iran to charge tolls on vessels passing through the Strait of Hormuz is under consideration as both a security and economic measure.

“We’re thinking of doing it as a joint venture. It’s a way of securing it — also securing it from lots of other people,” Trump said. “It’s a beautiful thing.”

OKing a toll would mark a dramatic shift in US policy toward Iran and maritime security in the region. Historically, Washington has pushed for free and open navigation through the strait, backed by naval presence to deter threats and ensure the flow of goods.

Iran has already begun demanding tolls via crypto to pass safely through the strait. Tehran also threatened to “destroy” any ships that attempt to cross the strait without Tehran’s go-ahead. 

“You must receive permission from Iranian Sepah navy for passing through the strait. If any vessel tries to transit without permission, will be destroyed,” an Iranian official was heard saying in audio shared with the Wall Street Journal by a crew member.

To keep the peace, Trump also threatened to impose massive 50% tariffs on countries sending military firepower to Iran, putting Russia and China on notice.

“A Country supplying Military Weapons to Iran will be immediately tariffed, on any and all goods sold to the United States of America, 50%, effective immediately. There will be no exclusions or exemptions!” Trump wrote in a signed Truth Social post.

Beijing and Moscow in the past have both helped Iran build military capacity — supplying missiles, air defense systems and technology intended to bolster Tehran and complicate matters for Washington.

Despite the hiccups, Trump praised the deal in a post to Truth Social saying, “A big day for World Peace!”

“There will be lots of positive action! Big money will be made. Iran can start the reconstruction process,” he said. “Just like we are experiencing in the US, this could be the Golden Age of the Middle East!!!” 

Secretary of War Pete Hegseth attributed the win to the US achieving “a historic and overwhelming victory on the battlefield” in the now-ended Operation Epic Fury.

“No other president has shown the courage and resolve of this commander in chief. President Trump forged this moment. Iran begged for this ceasefire, and we all know it,” Hegseth told reporters at the Pentagon early Wednesday.

“Operation Epic Fury was a historic and overwhelming victory on the battlefield. A capital V military victory. By any measure. Epic Fury decimated Iran’s military and rendered it combat-ineffective for years to come,” he added.
