US Vice-President JD Vance’s visit to Islamabad for peace talks with Iran to end the seven-week war has been put on hold after Tehran failed to respond to American negotiating positions, the New York Times reported on Tuesday.Vance was scheduled to depart on Tuesday morning for Islamabad, where talks were set to resume on Wednesday, the day the fragile ceasefire between the US and Iran is set to expire. Without an Iranian response, the diplomatic process was in effect paused, though the trip had not been cancelled, a US official was quoted in the New York Times report.As Tehran failed to respond, US President Donald Trump threatened to bomb Iran if it did not agree to a deal before the end of the two-week ceasefire, even as Pakistan urged the two sides to extend the truce and give diplomacy a chance. An Iranian Foreign Ministry spokesman said “no final decision” had been taken on whether to attend the talks.Even as diplomatic channels remained active, indications from Tehran pointed towards preparations for a possible resumption of hostilities. Reports suggested that Iran had undertaken military redeployments over the past two weeks and drawn up a fresh list of targets, anticipating that negotiations may collapse amid disputes over US demands and a reported naval blockade.Trump said on Tuesday that Iran would send a delegation for talks in Islamabad, but made it clear that Washington was prepared to resume bombing if the deal was not reached before the end of the ceasefire deadline. “They have no choice but to send them…. I think we’re going to end up with a great deal,” Trump said in an interview, projecting confidence while simultaneously signalling readiness for military action.Underscoring the narrowing diplomatic window, Trump indicated that he was reluctant to extend the ceasefire even if talks showed progress. “We don’t have that much time.… They have to negotiate,” he said, adding that the US was in a “very strong negotiating position” after weeks of military operations that he claimed had significantly degraded Iran’s capabilities. In a stark warning, Trump suggested potential strikes on critical infrastructure, including logistical networks used for missile movement, and asserted that the US military was “ready to go”.Adding to the diplomatic flux, Pakistan said it was still awaiting confirmation from Iran on participation in the proposed peace talks, effectively placing the onus on Tehran as the ceasefire deadline loomed. Attaullah Tarar, Pakistan’s Minister for Information and Broadcasting, said Islamabad was in “constant touch” with Iranian authorities and was making “sincere efforts” to bring them to the negotiating table.
