The report concluded that the Pentagon could not properly account for as much as $2 billion in payments to Pakistan over a three-year period from 2004 to 2007.
Auditors uncovered an array of questionable costs, including $45 million for roads and bunkers that may never have been built; $200 million for the operation of air defense systems even though Al Qaeda has no known aircraft; and overcharges for meals and vehicles used by Pakistani troops.
Overall, the report by the Government Accountability Office concluded that the Defense Department had routinely covered costs without verifying that they "were valid, actually incurred, or correctly calculated."
The Pentagon has paid about $5.6 billion to Pakistan in counter-terrorism reimbursement funds in the nearly seven years since the Sept. 11 terrorist attacks, by far the largest sum paid as part of the program to a counter-terrorism ally.
