Iran war could cost $2 billion per month, Congressional Budget Office estimates

# Why This Matters The Congressional Budget Office's estimate of $2 billion monthly in Iran conflict costs represents a direct compete between military spending and domestic priorities at a moment when Congress already faces difficult budget negotiations. A sustained conflict of this magnitude would consume resources equivalent to the entire annual budget for the National Institutes of Health or the Federal Highway Administration, forcing lawmakers to either raise the deficit, cut existing programs, or reallocate funds from other defense initiatives. Beyond the fiscal impact, a prolonged Iran conflict would likely strain the Navy and Air Force's operational capacity across other regions—including the Indo-Pacific and Europe—while potentially disrupting global oil markets and triggering broader Middle Eastern instability that could draw in allied nations. The $38 billion already spent since February underscores that this is no longer a hypothetical scenario but an ongoing drain on both the federal budget and military readiness.
