skinheads revolve around "the ethnic war which will be waged in the future and the denunciation of a global Jewish conspiracy to promote miscegenation" (see White genocide conspiracy theory). The white power skinhead movement is generally associated with neo-Nazism, in part, this is due to its origins in the National Front and the British Movement, along with the presence of former Nazis (especially former members of the SS) who mentored members of nascent German racist skinhead groups in the 1980s–1990s. Historian John F. Pollard contends that "the racist skinhead ideology is fundamentally neo-Nazi in inspiration." Camus and Lebourg also argue that although not all racist skinheads can be classified as 'neo-Nazi', neo-Nazism remains hegemonic in the far-right skinhead movement. Scholars concede at the same time the difficulty of separating the public use of the provocative and subversive aesthetics surrounding Nazi symbols from actual belief in, and commitment to, Nazi ideology. The early-20th century Judeo-Bolshevik and Judeo-Masonic conspiracy theories have since evolved into the idea of a Zionist Occupied Government (ZOG), which claims that Jews secretly control the governments of Western states. Their attitude toward the Holocaust ranges from outright denial to minimization of the death toll, and even to glorifying the event in the lyrics of white power bands such as No Remorse or Warhammer. Nazi theories of Slavs as Untermenschen ('sub-humans') have been largely abandoned in favor of a more "inclusive" concept of white supremacy. American neo-Nazism and white supremacism largely helped "crystallize" the Nazi imagery and have had a powerful influence on the worldwide movement, as evidenced by the popularity of David Lane's Fourteen Words and William Luther Pierce's The Turner Diaries, which some Combat 18 leaders regard as their "Bible". According to Camus and Lebourg, the Nazifying imagery of white power skinheads was "at first largely provocative", and sometimes a way for the proletarian youth "of responding to the sacralization of the memory of World War II". Pollard also notes that "adolescent rebellion", involving a desire to be different by rejecting prevailing societal norms by using shocking imagery (like the wearing of Nazi regalia by motorcycle gangs in the 1960s and punk rockers in the 1970s), probably plays some part in the decision to wear neo-Nazi or racist symbols, or even to adopt the ideas they embody. References to Nazism have also been less significant in countries like Italy or Hungary, where fascist figures like Benito Mussolini
