"This month, the Pentagon and the Iraqi government are finally closing the books on the program that handled all those Benjamins. But despite years of audits and investigations, U.S. Defense officials still cannot say what happened to $6.6 billion in cash — enough to run the Los Angeles Unified School District or the Chicago Public Schools for a year, among many other things. For the first time, federal auditors are suggesting that some or all of the cash may have been stolen, not just mislaid in an accounting error. Stuart Bowen, special inspector general for Iraq reconstruction, an office created by Congress, said the missing $6.6 billion may be "the largest theft of funds in national history." The mystery is a growing embarrassment to the Pentagon, and an irritant to Washington's relations with Baghdad. Iraqi officials are threatening to go to court to reclaim the money, which came from Iraqi oil sales, seized Iraqi assets and surplus funds from the United Nations' oil-for-food program."
