Speaking at a Veterans Day ceremony at Arlington National Cemetery, Trump declared that US forces had already defeated Iran militarily and suggested Washington could decide when to end the conflict.
“We won. It’s just a question of when we end it,” Trump said.
“I want to make sure we have a total victory, not a 93 percent victory,” he added, predicting that the conflict would end soon.
Tehran, however, showed little willingness to accept Washington's terms. Parliament Speaker Mohammad Bagher Ghalibaf said Iran was determined to end its prolonged state between war and peace through military deterrence, potentially without negotiations.
In an interview with Al Jazeera, Ghalibaf said Washington had not formally responded to Tehran's seven conditions for reopening the Strait of Hormuz and resuming talks. He insisted that those conditions must be fully implemented before either could proceed.
His remarks followed comments by President Masoud Pezeshkian on Monday that Supreme Leader Mojtaba Khamenei had ordered an end to the country's “no war, no peace” situation. Pezeshkian said Iran could resolve the dispute through negotiations but would not yield to pressure.
The impasse extends to Iran's nuclear program, one of the central disputes between the two countries.
Mohsen Rezaei, secretary of Iran's Supreme National Security Council, said Tehran would not transfer any of its enriched nuclear material abroad, rejecting a possible arrangement involving Russia.
“We have informed our Russian friends that the enriched material will remain in Iran, and we will use it ourselves,” Rezaei told Lebanon's pro-Hezbollah Al Mayadeen television.
Russia's Foreign Ministry said Wednesday that its offer to receive the material remained available, while emphasizing that Tehran alone would decide what happened to its stockpile.
The disagreement highlights the obstacles facing any diplomatic settlement, even as Pakistan continues efforts to mediate between Washington and Tehran.
Pakistani Prime Minister Shehbaz Sharif, who met Pezeshkian on the sidelines of the COP31 climate summit in Turkey, called for restraint and sustained diplomacy, saying negotiations offered the only path to lasting peace.
The Wall Street Journal reported Wednesday that US Vice President JD Vance was considering face-to-face talks with Iran's Supreme National Security Council Secretary Mohsen Rezaei, citing US and Middle Eastern officials and people familiar with the negotiations.
Trump has authorized Vance to negotiate with Iran, according to the report. Vance sent Rezaei a letter in October requesting a meeting, but no date has been set, with Doha under consideration as a possible venue.
But prospects for direct talks appeared uncertain. Mehdi Mohammadi, an adviser to Ghalibaf, said Tehran had rejected a request from US Vice President JD Vance for direct negotiations before Washington delivered its final response to Iran's proposal.
The Wall Street Journal, meanwhile, reported that Trump had privately questioned whether a Pakistan-brokered agreement reached in June had allowed Tehran to regroup before the United States imposed its naval blockade.
With negotiations stalled, Washington is seeking to intensify the economic pressure already imposed through maritime restrictions and sanctions.
The New York Times reported Wednesday that US officials had spent weeks unsuccessfully pressing Iran's neighbors, particularly Iraq, Turkey and Pakistan, to restrict trade across their land borders.
The effort gained a new dimension with the establishment of Task Force Iron Gate, a US Central Command initiative aimed at disrupting the movement of weapons, sanctioned goods and illicit revenue across Iran's land borders and the Caspian Sea.
But neighboring governments have resisted measures that could damage their own economies and provoke unrest in communities dependent on cross-border trade.
According to the Times, Iraq rejected a US request to close all but two crossings with Iran, while Turkey has largely declined to change its border policies.
The Group of Seven foreign ministers pledged Wednesday to maintain economic and political pressure if diplomacy failed to address Iran's nuclear program and regional security concerns.
Iran's response has combined diplomatic resistance with increasingly expansive military threats.
Rezaei warned Wednesday that any US military base involved in a renewed war against Iran could be targeted, including facilities in Europe.
“NO SAFE DISTANCE. NO SAFE HAVEN. NO IMMUNITY,” he wrote on X.
Other senior Iranian military figures issued similar warnings. Deputy armed forces chief Keyoumars Heydari said Iran had prepared an expanded list of potential targets beyond the Middle East, while Revolutionary Guards adviser Mohammadreza Naghdi said the armed forces had authorization to retaliate without geographical restrictions.
Mohammadi, the adviser to Ghalibaf, also warned that Iran could consider preemptive military action if Washington continued tightening economic pressure. He claimed the United States was preparing for a limited strike, although there was no independent confirmation of such a plan.
An adviser to Supreme Leader Mojtaba Khamenei also warned that countries helping enforce a blockade against Iran could be treated as participants in an act of war.
Those threats came as the Strait of Hormuz remained a flashpoint, complicating efforts to restore commercial shipping and energy exports from the Persian Gulf.
Reuters reported Wednesday, citing three sources familiar with the matter, that Iran had attacked navigation infrastructure on Oman's Didamar island used to support shipping through the waterway. The extent of any damage was unclear.
Iran's navy also said a tanker had caught fire after striking a mine east of the strait, describing the area as unsafe and restricted and urging shipowners to coordinate passage with Iranian forces.
