Trump's Iran push stalls as ceasefire talks hinge on deal terms

President Donald Trump’s latest effort to freeze the fighting with Iran has run into the same wall that has slowed his moves in Gaza and Ukraine: a pause can be announced, but the terms that make it real still have not been settled.

On May 27, U.S. and Iranian negotiators reached a tentative agreement to extend the ceasefire for 60 days and open a new round of talks on Iran’s nuclear program. But the language of the emerging memorandum remained unresolved, and Vice President JD Vance said it was still unclear whether Trump would sign off. The political risk is obvious: if Trump approves, he claims a diplomatic opening; if he does not, the fragile ceasefire can snap.

Trump has tried to frame the Iran talks as something different from the 2015 nuclear deal, while also warning that he could strike again if negotiations collapse. White House press secretary Karoline Leavitt put the pressure in stark terms in March, warning Iran would face “grave consequences” if no agreement was reached. That mix of threats and bargaining has bought time, but not a settlement.

The war in Iran began with U.S.-Israeli strikes on February 28, 2026, according to CNN’s timeline. The opening attacks killed Iran’s supreme leader and other senior officials, setting off a conflict that has since revolved around brinkmanship in the Strait of Hormuz and a ceasefire that remains shaky. The current talks are less a peace process than a contest over whether a temporary stop can be stretched into something durable.

Public patience for the military track appears thin. AP-NORC polling found most Americans think U.S. military action against Iran has gone too far. A Washington Post-ABC-Ipsos poll found 61 percent of respondents said the use of force against Iran was a mistake. That skepticism raises the cost of escalation while limiting the political payoff of inaction.

The same narrowing room to maneuver has been visible elsewhere. In Gaza, a ceasefire took effect in October 2025, and by October 13 all 20 remaining living hostages had been released along with hundreds of Palestinian prisoners. Even so, the truce has stayed unstable and humanitarian conditions in Gaza remain severe. In Ukraine, Trump pushed a short Russia-Ukraine ceasefire and prisoner exchange in May 2026, another stopgap that left the core questions unresolved.

Across Gaza, Ukraine and Iran, Trump has been able to force pauses. What he has not yet been able to produce is a settlement that lasts once the pressure lifts.
