In the planning phase of the 2003 Iraq invasion:
[1]
> As a result, the executive steering group and its supporting working groups spent extensive time on building a humanitarian assistance package for Iraq, but comparatively little time on the functions of a post-regime government outside of the oil ministry.
Surely with the focus on the oil ministry, post invasion operations were fully transparent and not at all suspicious!

> In October 2004, the audits conducted by IAMB and KPMG revealed the CPA's inadequate accounting system. IAMB failed its oversight process for several months because of procedural disputes and US manipulation. During this time illegal export of petroleum was conducted secretly from Iraq, and a large amount of funds for DFI were disbursed without accountability. According to the audits conducted by the Special Inspector General for Iraq Reconstruction (SIGIR), US $8.8 billion of the US$23 billion of Iraqi money disbursed for DFI has not been accounted [for].
> Iraq's oil infrastructure was damaged when the CPA took over. The CPA effected selected repairs. But the IAMB found that the CPA had chosen not to repair the meters on the pipelines. The IAMB told the CPA that they were concerned that the lack of metering made auditing Iraq's oil exports unreliable – making it impossible to detect fraud, deception or smuggling. The minutes of the IAMB meeting make clear that the CPA had assured the IAMB that they were in the process of repairing the meters – in bad faith. The CPA's authority came to an end with the meters unrepaired. Estimates of how much oil revenue was siphoned off during the year of the CPA's administration go as high as $4 billion – comparable to the amount Saddam Hussein is suspected of stealing during the entire duration of the oil-for-food program.
Uhhhhh... Right, thanks for keeping us safe defense industry!
