Looks like the winners in the war include contractors, particularly Halliburton/KBR. From the CPI report:
KBR, Inc., the global engineering and construction giant, won more than $16 billion in U.S. government contracts for work in Iraq and Afghanistan from 2004 to 2006—far more than any other company… In fact, the total dollar value of contracts that went to KBR—which used to be known as Kellogg, Brown, and Root and until April 2007 was a subsidiary of Halliburton—was nearly nine times greater than those awarded to DynCorp International, a private security firm…
According to David Walker, the comptroller general of the United States, the outsourcing of government has escalated across the board over the past five years, although oversight of the process has shrunk during this same period. In an interview with the Center for Public Integrity, Walker noted particular problems with military contracting. "We have identified about 15 systemic, longstanding acquisition and contracting problems that exist within the Defense Department—which is the single biggest contractor within the U.S. government—that we are still not making enough progress on," said Walker, who heads the Government Accountability Office. "I mean, this stuff isn't rocket science."
But not all contracts for Iraq and Afghanistan are reported in this federal data system, including awards originating at one contracting agency in Baghdad, which reports only some aggregate totals for inclusion in the central database. Because the agency has so far refused to furnish these missing contracts, the Center is now seeking copies via Freedom of Information Act requests.
