By forbearing to march behind the yin-yang flag at the opening ceremony of the Olympics, the South Korean athletes are making a bigger sacrifice than the North Koreans, in whose iconography the banner of the DPRK ranks lower than the party standard, which in turn ranks much lower than the Supreme Commander's standard, the flag of the personality cult — something to which the North Korean athletes may end up paying homage anyway by wearing their leader badges.
