Iran and the United States are locked in a clash of views as talks loom amid growing rallies by Iranians abroad. These global demonstrations call for action after thousands died in last month’s nationwide protests in Iran. The US wants to curb Iran's missile program and nuclear enrichment, demands Tehran has firmly rejected. Iran offered to dilute its highly enriched uranium in exchange for lifted sanctions but insists on peace without foreign interference. US President Donald Trump announced sending a second aircraft carrier to the Middle East, calling regime change in Iran “the best thing that could happen.” In Tehran, President Masoud Pezeshkian thanked regional mediators to avoid US military action and warned war would affect the whole Middle East. On Saturday, Iranians in cities like Munich, Los Angeles, Toronto, Sydney, and Melbourne rallied to demand an end to Iran’s religious rule. Reza Pahlavi, son of the exiled shah, urged the diaspora to join a “global day of action” to reclaim Iran from the Islamic Republic. Tens of thousands joined some of the largest protests by the Iranian diaspora since 2022-2023. These protests followed the killing of Mahsa Amini, a 22-year-old woman who died in police custody over hijab rules, sparking months of unrest. Families of those killed continue sharing footage online and holding ceremonies, like the recent 40-day mourning at Tehran’s Behesht-e Zahra cemetery. The Iranian government denies accusations of violence against protesters, blaming US and Israeli-backed terrorists. The UN and human rights groups report lethal force was used on peaceful demonstrators. Amnesty International warns of executions, including that of 18-year-old wrestler Saleh Mohammadi. Iran's judiciary confirmed some arrested reformist politicians are on bail, and many students detained during protests may soon be released. Still, tens of thousands remain imprisoned, with ongoing international concern about human rights abuses and limited information due to internet restrictions.
