Trump Warns Time Not on Iran’s Side Amid Escalating Nuclear Talks and White House Stance on Deal Deadlines

President Donald Trump warned Iran on Sunday that time is not in Tehran’s favor as negotiations over the ongoing conflict remain stalled, emphasizing that the United States is prepared to act if a deal is not reached.

In a post on Truth Social, Trump stated that the U.S. Is offering a “very fair and reasonable DEAL” but warned that if Iran does not accept, the United States will “knock out every single Power Plant, and every single Bridge, in Iran.” He added, “NO MORE MR. NICE GUY!” and declared, “IT’S TIME FOR THE IRAN KILLING MACHINE TO END!”

Trump also accused Iran of committing a “total violation” of the ceasefire for firing on ships near the Strait of Hormuz and said that U.S. Forces had damaged and seized the Iranian ship Touska as it attempted to break the blockade of the strait. He wrote that the U.S. Has “full custody” of the vessel after the Iranian crew refused to comply with naval orders.

The White House confirmed that Vice President JD Vance, envoy Steve Witkoff, and Trump’s son-in-law Jared Kushner will attend talks in Islamabad on Monday. A senior official told USA TODAY that discussions will focus on fully reopening the Strait of Hormuz for global oil transport and preventing Iran from acquiring nuclear weapons.

Despite the hardline tone, Trump said negotiators are returning to Pakistan for another round of talks, expressing hope that Iran will accept the offer. He added that the U.S. Blockade of Iran’s ports will remain in place while Tehran’s leadership works to unify around a proposal.

Iran’s top negotiator warned that Tehran will not negotiate “under the shadow of threat” and has prepared “new cards on the battlefield,” signaling readiness if the war resumes. The country’s forensics chief reported nearly 3,400 deaths since U.S.-Israeli strikes began on February 28.

The U.S. Has also boarded another sanctioned tanker overnight as part of efforts to disrupt support for Iran, according to the Pentagon. Iran demanded the immediate release of the seized vessel and vowed retaliation, heightening tensions around the Strait of Hormuz.

With the ceasefire set to expire soon, Trump said he is ready to resume bombing if talks do not progress. However, he left open the possibility of a deal, stating, “We’re going to end up with a great deal,” and insisting that Iran “has no choice” but to send a delegation to the negotiations.
