Body counts are notoriously inaccurate—and a poor yardstick for measuring progress on the battlefield. Nonetheless, a top U.S. official recently trumpeted the fact that the U.S.-led alliance has killed “more than 10,000” fighters of the Islamic State of Iraq and Greater Syria over the past year. That’s despite the fact that the alliance has regained little territory from the wide swaths of Iraq and Syria ISIS has gobbled up since 2013. But there is another body count when it comes to assessing the war on ISIS that is far more accurate—and far more telling: the Pentagon had expected to train about 24,000 Iraqis to fight ISIS by this fall, but will only manage to train 7,000, Defense Secretary Ashton Carter told the House Armed Services Committee on Wednesday.
