White House budget director Russell Vought told Congress on April 15 that the administration has no cost estimate for the Iran war and isn't ready to request funding for it. This is significant because Congress typically requires cost projections before approving war spending—Vought's inability to provide one suggests either the conflict's scope is still uncertain or the administration hasn't calculated expenses yet. The CNBC report indicates peace talks with Iran are ongoing alongside military operations, which may explain why a final cost cannot yet be estimated.
