Hagel: Top-to-bottom changes needed in nuke force

WASHINGTON (AP) - Defense Secretary Chuck Hagel is ordering top-to-bottom changes in how the nation's nuclear arsenal is managed, vowing to invest billions of dollars more to fix what ails a force beset by leadership lapses, security flaws and sagging morale. Hagel is scheduled to announce today the results of two reviews - one by Pentagon officials and a second by outside experts - and to spell out actions he has ordered to improve nuclear force management. Two senior defense officials discussed the Hagel plan Thursday on condition of anonymity because they were not authorized to be cited by name.
