One partner country told CBS News there is a need for a pause in fighting, particularly given the intensity of Iranian strikes that have been battering Kuwait and Bahrain. Those weapons remain in the arsenal, officials said, but are being used more sparingly. The Biden administration delayed giving ATACMS to Ukraine in part because drawing from those inventories could undermine U.S. military readiness, CBS News previously reported. The U.S. has comparatively healthier supplies of the shorter-range Guided Multiple Launch Rocket System, or GMLRS, which is also fired from the HIMARS launcher, the officials told CBS News, allowing commanders greater flexibility for targets within its range. Many of the weapons being fired in weeks or months cannot be replaced for years.
