Go ahead and puke then; your mind is obviously made up and has revised history to suit your position. You're ignoring that at the time Congress passed an authorization of force, UN resolutions were in place allowing the strike, huge public majorities supported action, and there was widespread agreement among most politicians of both sides that a WMD program of some sort was being undertaken. Your side put all its chips on stopping the invasion and lost big, same as the GOP did for Obamacare.
Gawd. The Bushistas fashioned a national tragedy, 9/11, into a club to use against all enemies, foreign and domestic. With us or against us, with a terrarist! under every rock & craven, despicable terrarist! coddlers everywhere.
The distortions, lies, fearmongering & bloodlust leading up to the invasion were a masterful exercise in propaganda of the worst sort. It was one of the most shameful events in our history, so much so that many Americans simply can't face the truth of it.
Naturally the common people don't want war; neither in Russia, nor in England, nor in America, nor in Germany. That is understood. But after all, it is the leaders of the country who determine policy, and it is always a simple matter to drag the people along, whether it is a democracy, or a fascist dictatorship, or a parliament, or a communist dictatorship. Voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is to tell them they are being attacked, and denounce the pacifists for lack of patriotism and exposing the country to danger. It works the same in any country.
