Is Democracy A Cause of Peace?

The West has been discussing the relationship between democracy and peace for a long time. The “Democratic Peace Theory” was put forward as early as Kant’s period, furthermore, this theory flourished again after the Second World War. After the end of the Cold War, Fukuyama and other scholars reinterpreted the “Democratic Peace Theory” and had a profound impact on the foreign policies of today’s Europe and the United States. The purpose of this article is to analyze the theoretical logic of the “Democratic Peace Theory” and its application in reality, as a consequence to examine how this theory provides an ideological excuse for the intervention and expansion of the world war situation.
