Abstract: As two different alternatives of modernity construction, radical revolution and “conservative alternative” were in antagonism and competition in East Asia during the early stage of the Cold War. “Radical revolution” seemed to gain the upper hand for a time, but it could not be so dominating as to exclude all “the others” thoroughly. After 1970s, the success of “conservative alternative” characterized by the rising of the “Four Asian Tigers,” together with the self-transformation in domestic and foreign policies in nations of radical revolution, has not only molded and remolded the construction of modernity in East Asia, but also led to the transform of the Cold War in East Asia. With the end of the Cold War, there is a confluence of radical revolution and “conservative alternative” in many aspects.
