Over the past six years, the U.S. military has spent $2 billion on 16,000 humanitarian projects--including

roads and schools--as part of its nation-building efforts in Afghanistan. But a soon-to-be-released audit

obtained by the Washington Post reveals that, once under local control, many of these projects go

neglected. The audit raises doubts as to whether the Afghan government can sustain infrastructure

improvements when the U.S. looks to withdraw forces later this year.
