WASHINGTON — In taking a deep look at trouble inside U.S. nuclear forces, Defense Secretary Chuck Hagel is searching for the root causes of recent Air Force missteps but also for ways to make the nuclear warrior’s job more attractive at a time when the military has turned its attention away from such weapons.

Nuclear missteps revealed WASHINGTON (AP) — The Air Force stripped an unprecedented 17 officers of their authority to control — and, if necessary, launch — nuclear missiles after a string of unpublicized failings, including a remarkably dim review of their unit’s launch skills. The group’s deputy commander said it is suffering “rot” within its ranks.
