The United States has basically won the war in Iraq. No insurgent or terrorist group can declare victory or claim Americans are evacuating Iraq's cities because they were beaten. America's most modest foreign policy objectives there have been largely secured. Saddam Hussein's toxic regime has been replaced with a more or less consensual government. I doubt very much that Iraq will seriously threaten the United States or its neighbors any time soon. It isn't likely to be ruled by terrorists as it probably would have been if the United States left between 2004 and 2007. It's a relief. A few years ago, I was all but certain the U.S. would withdraw under fire and leave Iraq in the hands of militias. Even so, many have a hard time feeling optimistic about the future. Iraq remains, in some ways, a threat to itself.
