According to The Wall Street Journal, U.S. military operations against Iran have consumed approximately $80 billion in Pentagon resources as of June 21, with internal Defense Department estimates warning of potential operational funding deficits by summer if spending continues. The department may need emergency Congressional appropriations, according to sources familiar with ongoing budget discussions.
The conflict has also significantly depleted critical American weapons stockpiles, including THAAD and Patriot missile interceptors. Research institutions note that replenishment cycles for certain munitions extend several years, raising concerns over supply chain capacity.
