The United States and Iran did not reach a deal because Washington failed to win the other side’s trust, Tehran’s lead negotiator said on Sunday.In his first comments since the marathon round of talks in the Pakistani capital Islamabad broke up, Parliament Speaker Mohammad Bagher Ghalibaf wrote on social media: “We have the necessary good faith and will, but due to the experiences of the two previous wars, we have no trust in the opposing side.“The opposing side ultimately failed to gain the trust of the Iranian delegation in this round of negotiations.”The talks began on Saturday and went on past dawn before US Vice-President J.D. Vance announced there was no deal, citing Tehran’s failure to make a “fundamental commitment of will” not to develop nuclear weapons.“We have been at it now for 21 hours, and we’ve had a number of substantive discussions with the Iranians. That’s the good news,” he told a press conference.“[The] bad news is that we have not reached an agreement, and I think that’s bad news for Iran, much more than that, it’s bad news for the United States of America.”He did not respond to questions about whether the two sides would go to war again.
