I have to pipe up here. Gackt didn't dress up in a Nazi Uniform to glamorize Nazi's or because he thinks Nazi uniforms are cool. The purpose of the concerts was to criticise war. Basically Gackt organizes his concerts like plays or musicals and uses them to tell a story. In his Requiem et Reminicense I and II the story takes place during World War II and revolves around two different soldiers. Here a fan summarizes the events of the story and explains what there about http://groovy-walls.livejournal.com/58772.html. Although the story itself is a work of fiction it references much of WWII history.
