BROTHER, CAN YOU SPARE $4 BILLION? This article on revised Congressional Research Service estimates of spending on the Iraq War is pretty dull until the end, but then it starts to get interesting. The report apparently contains such phrases as "These factors, however, are not enough to explain a 50-percent increase of over $20 billion in operating costs" and "These reasons are not sufficient, however, to explain the level of increases." Relatedly, the Post reports that "Of the total war spending, the CRS analysis found $4 billion that could not be tracked. It did identify $2.5 billion diverted from other spending authorizations in 2001 and 2002 to prepare for the invasion." I'm fairly sure you're not allowed to "divert" money from other spending authorizations, and you're certainly not supposed to lose $4 billion in untrackable spending. Nor does it sound entirely appropriate for the Pentagon to be running its operation in such a way that the CRS can't discern the causes of 50 percent spending increases. All the sort of thing a real congress would hold some hearings on, and, once again, I won't be holding my breath.
