The Korean People's Army is an entire military of metaphorical complete monsters. Their leader, Kim Jong-un, launches an attack on America shortly after he launches his "message of peace" satellite broadcast, which is actually an EMP that kills power to 90% of the North American continent, that results in the death of a large amount of its population overnight, slaughtering civilians with impunity and toothy grins. One of his men is seen with a dead baby in its mouth. They then irradiate the Mississippi river and turn America into a near-apocalyptic world. Kim Jong-un claims that the reason they invaded was to "help" the Americans in their bad economic situation.... through labor camps, execution squads, and mass graves.
