President Donald Trump has warned that while the United States prefers diplomacy in dealing with Iran, all military options remain firmly on the table as tensions spike ahead of planned talks in Oman. U.S. and Iranian officials are set to meet there in what would be the first official encounter since the June 2025 war, with Iran’s Abbas Araghchi facing a U.S. team including Steve Witkoff and Jared Kushner, as Washington pushes to prioritize Iran’s nuclear program and raise missile and proxy issues that Tehran insists it will not discuss beyond the nuclear file. The U.S. has also urged its citizens in Iran to leave immediately, issuing a stark February 5 advisory telling Americans to be ready to depart without government assistance, even as regional powers like Saudi Arabia and Qatar call for restraint and the world watches whether this diplomatic opening can ease the dangerous U.S.-Iran standoff.
