A dozen years later, American politics has reached a rough consensus about the Iraq War: It was a mistake. Politicians hoping to be president rarely run ahead of public opinion. So it's a revealing moment when the major contenders for president in both parties find it best to say that 4,491 Americans and countless Iraqis lost their lives in a war that shouldn't have been waged.
Many people have been saying that for years, of course. Polls show most of the public have judged the war a failure by now. Over time, more and more Republican politicians have allowed that the absence of weapons of mass destruction in Iraq undermined Republican President George W. Bush's rationale for the 2003 invasion.
