Immediately after the 2003 invasion most polls within the United States showed a substantial majority of Americans supporting war, but that trend began to shift less than a year after the war began. Beginning in December 2004, polls have consistently shown that a majority thinks the invasion was a mistake. As of 2006, opinion on what the U.S. should do in Iraq is split, with a slight majority generally favoring setting a timetable for withdrawal, but against withdrawing immediately. However, in this area responses vary widely with the exact wording of the question.
