Donald Trump's threat to Oman highlights U.S. frustration with the Iran war and declining regional influence. Despite Oman's mediation, Iran resists concessions, debunking Trump's claims of a deal. The conflict reveals profound U.S. security strategy failures; bases are liabilities, and threats are ineffective. The author argues the old security architecture is shattered. Persian Gulf nations must forge a new regional order, potentially a cold peace between Arab states and Iran. This requires moving beyond the American security umbrella, acknowledging the failure of Iran containment.
