If Japanese professor Yuki Asaba is to be believed, North Korea’s shenanigans have more than a bit to do with children. Asaba thinks Kim Jong II’s proficience at a children’s strategy game called rock-paper-scissors—in which a player’s success depends on his ability to predict the opponent’s actions—can explain his ability to hold more powerful, but predictable, nations at bay. It’s not exactly high strategy, but for the child who walks through Seoul’s War Memorial (and others like him), this is one game that might be useful to remember.
