In September 2001, America introduced a new discourse called "war on terrorism" to wage a war on the so-called international network of terrorism as a response to the September 11 attack on the World Trade Center (WTC) in New York. Since then, the word "terrorism" has been even more extensively covered in the world-wide media. It is the concern of this book to analyze the discourse on terrorism in the Newsweek magazine, specifically in its September 24, 2001 edition, to find links that can explain the dialectical relationship between language and power through an ideological functioning message; which later can contribute to maintaining hegemony and unequal relations of power. In doing so, the author utilized Norman Fairclough's Critical Discourse Analysis (CDA), a five-stage analytical methodology that perceives language within a three-dimensional framework (text, discourse and society). This book, therefore, will be of direct relevance to teachers, researchers or students majoring in linguistics or literary criticism as well as those who are interested in the field of social studies in general.
