Yesterday I watched "Johnny Mad Dog", but I didn't quite understand it. Just like the theme, letting children participate in cruel battles is itself an incomprehensible thing. Such plots have been presented in films like "Blood Diamond", "Lord of War", "Hotel Rwanda" and so on. Maybe because the cost of dismissing minors is relatively low, after the armed struggle ends, politicians can casually dispose of these inexperienced children. Just like in the movie when Johnny asks the不死general for his dismissal fee and only gets scolding in return.
