The ongoing nuclear threat from “the North” is not supported by most of the international community, but it does in a weird way benefit from the conciseness of the Korean language. It is only the prefix “핵” that can turn anything into something nuclear, and in many occasions the resulting words sound cute, at least to a learner’s ears.
