The following is an English translation of Kim Jong Un's statement as published by @KCNA Watch:
The speech made by the US Chief Executive in his maiden appearance on the UN arena in the prevailing serious circumstances, in which the situation on the Korean peninsula has been rendered tense as never before and is inching closer to a touch-and-go state, is arousing worldwide concern.
A certain degree of my guess was that he would make stereotyped, prepared remarks a little different from what he used to utter in his office on the spur of the moment as he had to speak on the world’s largest official diplomatic stage.
But, far from making somewhat plausible remarks that can be helpful to defusing tension, he made unprecedented rude nonsense one has never heard from any of his predecessors.
A frightened dog barks louder.
I would like to advise Trump to exercise prudence in selecting words and to be considerate of whom he speaks to when making a speech in front of the world.
The mentally deranged behaviour of the US president openly expressing on the UN arena the unethical will to “totally destroy” a sovereign state, beyond the boundary of threats of regime change or overturn of social system, makes even those with normal thinking faculty reconsider discretion and composure.
His remarks remind me of such words as “political layman” and “political heretic” which were in vogue in reference to Trump during his presidential election campaign.
After taking office Trump has rendered the world restless through threats and blackmail against all countries. He is unfit to hold the prerogative of supreme command of the military forces of a country, and he is surely a rogue and a gangster fond of playing with fire, rather than a politician.
His remarks which described the US option through straightforward expression of his will have convinced me, rather than frightening or stopping me, that the path I chose is correct and that it is the one I have to follow to the last.
Now that Trump has denied the existence of and insulted me and my country in front of the eyes of the world and made the most ferocious declaration of war in history that he would destroy the DPRK, we will consider with seriousness taking a corresponding, highest level of hard-line countermeasure in history.
Action is the best option in treating the dotard who, hard of hearing, is uttering only what he wants to say.
As a man representing the DPRK and upon the dignity and honour of my state and people and upon all my own, I will make the man holding the prerogative of supreme command of the US pay dearly for his rude nonsense calling for totally destroying the DPRK.
This is not a rhetorical expression loved by Trump.
I am now thinking hard about what response he could have expected from us when he allowed such eccentric words to trip off his tongue.
Whatever Trump might have expected, he will face results beyond his expectation.
I will surely and definitely tame the mentally deranged US dotard with fire.
