This chapter explores the failure of the Democratic Labour Party(DLP) in the 2000s, focusing particularly on its leadership, which proved unable to develop the right strategies or prevent factionalism that, together, eroded its popular influence. There is strong evidence that DLP is not yet a moderate socialist party, and this originates from the party's platforms, key strategies and campaigns. The formation of this platform in the history of socialism is the fruit of the ideological struggle between two factions: the revolutionary Marxist-Leninist socialist movement and the revisionist movement. Like the DLP in Korea, the Japanese Social Democratic Party(JSP) failed to become a majority or ruling party for thirty-three years. The result of rapid economic development and prosperity, Korean workers and the middle class, once a key ally for the working class in the democratisation era, preferred gradual reform. the meantime, the DLP was silent on two critical issues about North Korea: the development of nuclear weapons and human rights violations.
