The point of the Iraq lie isn't simply a redirection that "the US also does it." it's that the empire is capable of widescale deception to manufacture consent when the need arises. you may have realized it was a crock, but enough people were fooled the wholesale destruction of multiple sovereign nations went off without a hitch. "Bush lied, people died" only became the majority opinion after they had gotten away with it. Even now the popular consensus is that "mistakes were made," not that there was a wilful deception for the sake of expanding US global military hegemony.
