It may not have felt like war for people in the US but for people in Iraq it certainly did.
Actually relevant is a year later the vote about Iraq, in which a majority, 157/267, of U.S. Democrat Representatives and Senators were opposed. Left up to the decision of Democrats, there would be no Iraq war. I don't know how people vote Republican just 20 years later. That is lost on most people. I would know, I grew up in a rah rah Bush household.
