Islamic fundamentalism has been one of the challenging topics in the international affairs during the past couple of decades. After the collapse of communism at the outset of 1990s, this discourse has strengthened its position. September 11 event, which surprised the world, shows the spread of the pragmatic power of this talk. The discourse of Islamic fundamentalism has been indeed turned mere thought to action. However, Islamic fundamentalism, as a radical interpretation of Islamic religion, has had a special position in international affairs. Fundamentalists, unlike the other Islamic groups like moderate Islamists or Secular Islamists, are trying to confront Western School of thoughts (human right, democracy, globalism, terrorism and secularism) and to challenge the power of the West. They are trying to prove that these indices are not pervasive and problem solving, and that western teachings and school of thoughts need to be looked upon from another point of view. The main question in this article is how fundamentalism, as a discourse has challenged Western Hegemony? To answer this question, Laclau and Mouffe’s approach was employed to assess the universal validity of Western most cherished concepts such as human rights, globalization, democracy and terrorism from Islamic fundamentalist patters of thought.
