This article discusses the failure of the Iraqi political elites to resolve the key problems brought about by the occupation of Iraq in April 2003, even after the declaration of the Iraqi constitution in 2005. The article holds that the new constitution could not be implemented and was unsustainable for purely internal reasons. It was unable to provide answers to the new questions and facts, and the new tactical alternatives it created to produce hybrid regimes from 2006 were incapable of overcoming the structural crisis of the regime. This was especially the case since the attempts described as consensual, aimed to preserve the delicate political situation on the basis of the existing balance of power—rather than on the basis of a governing frame of reference accepted by all—did not transform into binding political conventions for the political groupings representative of the ethnic and religious components of Iraq, and at a minimum did not transform into agreements respected by all sides.
