The U.S. war with Iran has severely depleted critical missile stockpiles, including Tomahawks and Patriot systems, raising concerns about readiness for potential conflicts with China or Russia. Defense Secretary Pete Hegseth requested $67 billion to replenish these munitions, though officials remain divided on the severity of the shortfall. Meanwhile, Ukraine faces acute shortages of U.S.-made Patriot missiles, leaving it vulnerable to Russian ballistic attacks as it seeks alternative defense strategies and international aid.
