This paper addresses the impact of the antiwar movement (2002-2004) in the United States by analysis the three main coalitions at that time: ANSWER, UFPJ and Win Without War. New concepts and tools have been provided within discourse theory that can improve the analysis of framing and impact. Furthermore, the failure in discourse dynamics of the antiwar movement (2002-2004) is analyzed with a qualitative approach. Finally, we study the cultural context of 9/11, demonstrating that the best analysis for culture might not be ideational and static but, rather, contextual and dynamic.
