The U.S. justification for the Iraq War has been widely criticized both within and outside the United States by a range of common and official sources.[Putting this debate aside, the prosecution of the war effort along a number of lines has often been criticized by both supporters and critics of the invasion.
Most notably, the U.S. and its allies have been criticized by opponents for not devoting enough forces to the mission, not preparing sufficiently for post-invasion Iraq, and for encouraging and perpetrating systematic violations of human rights. Critics have also railed against the increased human and financial costs as the battle has continued.
