From the Summary: "A large-scale assistance program has been undertaken by the United States in Iraq since mid-2003. To date, nearly $45 billion has been appropriated for Iraq reconstruction. On December 26, 2007, H.R. 2764, the FY2008 Consolidated Appropriations Act, was signed into law (P.L. [Public Law] 110-161). Although it specifically rejects most regular or supplemental economic assistance to Iraq under the State/Foreign Operations appropriations, it provides about $2.1 billion in reconstruction assistance, mostly for the training of Iraqi security forces. […] Reconstruction priorities have changed over time. Allocations within the Iraq Relief and Reconstruction Fund (IRRF), the main U.S. assistance account in the first few years, mirrored shifting events on the ground. However, funds shifted to security and democratization in the period from 2004 to 2006 meant fewer funds available for electric power and water projects. At this time, most large-scale infrastructure programs are no longer funded; however, many small-scale, targeted community-level infrastructure efforts are funded under the Commander's Emergency Response Program (CERP). The key emphases of the aid program are the training of Iraqi forces and programs assisting the development of Iraqi governing capacities and supporting the work of the Provincial Reconstruction Teams (PRTs). The report will be updated as events warrant.
