Minwoo Yun, a professor at Gachon University, informs that North Korea’s use of YouTube as a tool for cognitive warfare poses a critical threat to liberal democracies worldwide. He believes that North Korea’s YuMi and Song A channels, which portray the daily lives of young women and girls in North Korea, are part of Pyongyang’s attempt to counterbalance its negative image, including its aggressive nuclear threat, and potentially sway public opinion in its favor. Professor Yun analyzes that viewers may unconsciously associate the characters in the videos with North Korea, leading to the development of generally positive sentiments towards the country. He cautions that this, in turn, can result in negative attitudes towards messages from their own government, international community, and mainstream media on North Korean issues, perpetuating conspiracy biases and attitudes.
