The United States has expended a significant number of missiles during escalating tensions with Iran, raising questions about its long-term ability to sustain a prolonged conflict. Reports suggest these missiles are difficult and costly to replace, potentially impacting the “arsenal of freedom.” This comes as the US appears to be pausing direct military action against Iran, following recent attacks. Analysis is now focused on determining whether this pause is strategic, linked to a genuinely reduced stockpile of weaponry, or both. Concerns are growing regarding the sustainability of US defense capabilities in the region should conflict reignite. The depletion of missile stocks could significantly limit future options for the US in responding to Iranian aggression or regional instability. This situation requires reassessment of defense strategies and procurement policies.
