at Dongseo University, while race-based nationalism in North Korea strengthens patriotism towards the state and vice versa, in South Korea it undermines it: Due to traditional state support for race nationalism fostered during the 20th century, South Koreans have come to view positive achievements as being a result of inherent racial characteristics, whereas negative events are attributed to the incompetence and malevolence of the South Korean state: It is said that one of the reasons the South Korean state during the 20th century decided to extol race-based nationalism over civic nationalism was that being an authoritarian military junta at the time, it did not want to extol republican principles that might be used to criticize it in turn. That said, civic state-based nationalism was said to have been stronger during those years than in contemporary post-democratization South Korea, albeit still tenuous. Ironically, though fostered by a right-wing regime at the time, today race nationalism in South Korea is shared across the political spectrum. For instance, when the South Korean pledge of allegiance was reworded in 2007 to use less racialist language, it was left-leaning South Koreans who notably objected to a change. South Koreans' lack of state-based nationalism (or patriotism) manifests itself in various ways in the country's society. For example, there is no national holiday solely commemorating the state itself and many South Koreans do not know the exact date their country was founded. The closest analogue, Constitution Day, ceased to be a national holiday in 2008. The Liberation Day holiday, which is celebrated each August, shares its date with the establishment of the South Korean state. However, celebrations during the holiday choose to forgo commemorations of the South Korean state or its establishment in favor of focusing and extolling other aspects. As a result, many South Koreans do not know the exact date their own state was established, in contrast to North Koreans, who do. In contrast, a holiday marking the mythological formation of the "Korean race" in 2333 BC is commemorated with a national holiday in South Korea each October. The "Hell Chosun" phenomenon and a desire among many South Koreans to immigrate have also been cited as an example of South Koreans' general lack of nationalistic patriotism towards their state. The lack of state-based nationalism manifests itself in diplomacy as well; the lack of a strong, resolute response by South Korea to North Korea's attacks against
