Actually yes, they did. You should read some books like Imperial Life in the Emerald City that speaks about how the rebuilding effort tried to modernize Iraq and build back up their infrastructure and economy. It largely looks specifically at how America approached rebuilding their various ministries and the overarching strategy and why it failed.
But like always happens in imperialism things aren't sunshine and roses. Corruption, human nature, improper strategy, ego, the setback from the initial war, anti-occupation, lack of human resources, ignorance of culture and numerous other forces make it impossible to reach any semblance of an ideal.
