According to Suh Dae-sook, the cult of personality surrounding the Kim family requires total loyalty and subjugation to the Kim family and establishes the country as a one-man dictatorship through successive generations.[8] The 1972 constitution of North Korea incorporates the ideas of Kim Il-sung as the only guiding principle of the state and his activities as the only cultural heritage of the people.[9] According to New Focus International, the cult of personality, particularly surrounding Kim Il-sung, has been crucial for legitimizing the family's hereditary succession,[10] and Park Yong-soo said in the Australian Journal of International Affairs that the "prestige of the Suryong [supreme leader] has been given the highest priority over everything else in North Korea".[11]
