The Air Force has spent decades and billions of dollars perfecting its abilities to locate, identify and strike targets immediately after getting the go-ahead orders. Under the “time-sensitive targeting” rubric, the Air Force has acquired a formidable arsenal of advanced fighter jets, bombers and smart munitions. This wealth of technology has made it possible to hunt and kill a target within minutes, said Gen. Ronald Keys, the outgoing chief of the Air Combat Command. “The time-sensitive targeting loop is down to seven minutes,” he said. But even that prowess doesn’t necessarily help win wars. Iraq is a case in point, Keys said. “The people I really want to kill get away within two minutes.”
