"North Koreans feel more anger toward Japan. The Korean War lasted for three years, but Korea was annexed by Japan for 35 years, which is a lot longer than the Korean War. More evidence and historical archives about the ruthless Japanese imperialism exist than those about Korean War. Hence, despite the fact that North Korea works so hard to make its people hate America, young North Koreans feel more anger and resentment towards Japan and what they did to Koreans during the annexation and World War II. In this sense, the North Korean historical education system has been successful."
