King Jung Un has quite a bark and possibly bite when threatened by Trump; These two have been at each others' throats for quite a while. Mostly adding fuel to a fire whilst continuing to compete in the non-stop race to make the other look smaller with even more ridiculous buffoonery... Although I have to admit that this response has quite some class, flair and very specifically targets Trump more than anyone else.
