A statement published in a Pyongyang-based newspaper hit out at Donald Trump, who has adopted a hard-line stance during this year’s nuclear crisis.
The opinion piece in Minju Chosen, one of North Korea’s several propaganda rags, told Mr Trump to temper his policy with the hermit state.
The piece claimed America was terrified after a series of North Korea missile tests this year, the most recent of which used Kim’s most powerful weapon yet.
It said: “Frightened by the DPRK’s successful test-fire of ICBM Hwasong-15, old lunatic Trump talked about ‘way of serious approach’.
The article said this was a “loud of rubbish” and claimed America’s “nuclear war maniacs” suffered from “death-bed symptom”.
It said the USA needed to “behave with reason” or face “destruction”.
The statement concluded: “The Trump cult’s talk about ‘military counteraction’ is just ridiculous as it is incapable of judging what the declaration means.
“We warn him once again that if his regime resorts to military counteraction after losing discretion, it will face a tougher countermeasure by the DPRK and fall deeper into a quagmire.
