What must happen for the US and Iran to reach a peace deal?

As US President Donald Trump issued yet another ultimatum pressuring Iran into striking a peace deal, the two sides stood far apart amid a trust deficit, a guarantor vacuum and Israel’s role, analysts said.Trump extended the deadline for a deal calling on Iran to reopen the Strait of Hormuz until Tuesday 8pm Washington time – his third time doing so since the war began on February 28.Iran faced the “complete demolition” of its power plants and bridges if no deal was reached, Trump said on Monday, adding: “The entire country can be taken out in one night, and that night might be tomorrow night.”As the deadline approached, Reza Amiri Moghadam, Iran’s ambassador to Pakistan, which has sought to broker a truce between the warring sides, said in a social media post that Islamabad’s “positive and productive endeavours” in goodwill and good offices to stop the war were “approaching a critical, sensitive stage”.Motorists ride scooters near a large political billboard depicting missiles being fired behind Iranian demonstrators in solidarity with the government at Valiasr Square in Tehran on Sunday.
