The United States has gone the longest period without a combat casualty since September 11. As of Wednesday, there has not been a combat-related fatality for the past 75 days—the longest stretch since 2002. The figure came up during a heated exchange between a the parent of a veteran killed in Afghanistan and a congressman who will vote on yet another war. Fred J. Boenig questioned Adam Kinzinger's self-described "hawkish" approach to ISIS. “This is no disrespect, but when you said that, the only thing I can hear is a knock on my door again,” Boenig said. “I have one question: Do know how many days it has been since the last U.S. casualty? The last military casualty?” Kinzinger did not know.
