“While DOD has provided considerably more justification material for its war cost requests beginning with the [fiscal year] 2007 supplemental, many questions remain difficult to answer — such as the effect of changes in troop levels on costs — and there continue to be unexplained
discrepancies in DOD’s war cost reports, the CRS report stated.
That led the GAO to draft a letter to Congress March 17, saying the $108 billion the Pentagon has recently requested is based on “unreliable” financial data and should be considered an “approximation,” which, technically, could be interpreted to mean the Pentagon’s accounting methods underestimated the cost of the war.
“Over the years, we have conducted a series of reviews examining funding and reported obligations for military operations in support of [the global war on terror], the letter, addressed to Congressional committees, says. “Our prior work has found the data in DOD’s monthly Supplemental and Cost of War Execution Report to be of questionable reliability. Consequently, we are unable to ensure that DOD’s reported obligations for [the global war on terror] are complete, reliable, and accurate, and they therefore should be considered approximations...GAO has assessed the reliability of DOD’s obligation data and found significant problems, such that these data may not accurately reflect the true dollar value of obligations [for the global war on terror.]”
A Pentagon spokesman did not return calls for comment. But a GAO spokeswoman said the DOD has been struggling with “deficiencies in the Pentagon’s financial management system” that contributed to the unreliable data. She would not elaborate.
Although studies have surfaced stating that the cost of the Iraq war could soar past $2 trillion, the Congressional Budget Office said trying to estimate future costs for the war is difficult “because DOD has provided little detailed information on costs incurred to date.”
“The Administration has not provided any long-term estimates of costs despite a statutory reporting requirement that the President submit a cost estimate for [fiscal year] 2006-2011 that was enacted in 2004,” the CRS said.
