In the progressive course of the 21st century, Globalization in the field of politics and economic is developing actively, and it makes cultural Globalization a common phenomenon. So far, globalized development has become the premier subject in the core issues of international politics. Though globalization has become an unstoppable trend, it doesn't mean that the whole world has become a worldwide homogenized system. On the contrary, the complexity and diversity of the cultures of the world still exist. To claim, there is a peaceful situation worth yearning for during the development of globalization, while the call for localization and differentiation is also becoming higher and higher. The seesaw effect between fragmentation and integration has formed the landscape of the world's order today. Therefore, whoever wants to fathom the development of the world must acknowledge that the construction of the course of world's globalization is made by the powers of fragmentation and integration. This article based on the treatise of "Jihad vs. McWorld" by the American scholar professor Benjamin R. Barber tries in a progressive way to analyze "regional nationalism" and "globalism", the two main axis of modern conflicts, each of which stand for a complete opposite force and direction. In the article, "Jihad" is lead by localized, narrowed racial hatred, while "McWorld" by global market capitalism. The former tries to rebuild an ancient sub-nation and a racial barrier within, the latter leaks in from the outside, making the boundary lines obscure between nations. The two forces affect each other dialectically and form the current development of conflicts and fusion between cultures in the world. In addition to making analysis on the main factors of the cultural conflicts, this article discusses the strategies made against the fusion of cultures around the world, hoping to provide thoughts to a fine direction towards world peace.
