The United States has reportedly expended a substantial portion of its missile defence interceptor inventory in support of Israel amid the recent conflict with Iran. According to a report by The Washington Post, US forces launched over 200 Terminal High Altitude Area Defense (THAAD) interceptors, along with more than 100 Standard Missile-3 (SM-3) and Standard Missile-6 (SM-6) interceptors from naval vessels in the eastern Mediterranean. This operation may have consumed nearly half of the Pentagon’s interceptor stock, raising alarms about US readiness for future threats. In contrast, Israel deployed fewer than 100 Arrow and around 90 David’s Sling interceptors. Analysts noted that the US shouldered a heavier operational burden than previously acknowledged, engaging twice as many Iranian missiles as Israel. Concerns have emerged among US allies, particularly Japan and South Korea, regarding the depletion of US missile defence capabilities. Pentagon officials defended the distribution of military responsibilities, asserting that both nations shared the defensive burden equitably. The report arrives as tensions with Iran continue, with President Donald Trump emphasizing the necessity of preventing Iran from acquiring nuclear weapons.
