The Pentagon's own inspector general confirmed that this lack of concern for procedural safeguards was blatant and commonplace. That makes it hard to come to any conclusion other than that they were ignored rather than expedited or poorly executed.
It's also hard to come to any conclusion other than that the spending of taxpayer funds in Iraq bordered on, or actually was, simple and straightforward corruption.
Given the magnitude of the spending involved, Iraq may be the Bush administration's contribution to the biggest public corruption scandals of all time like Boss Tweed in New York, James Michael Curley in Boston, and Teapot Dome.
