In a statement carried by the North's state-run Korean Central News Agency, North Korea's First Vice Foreign Minister Choe Son-hui said President Trump's remarks hinting at a possible military strike against Pyeongyang would pose a "very dangerous challenge" if they were not made by mistake.
Choe added Pyeongyang could resume the tit-for-tat name-calling against the U.S., if similar expressions are used again.
The senior diplomat said it's more displeasing that Trump referred to the North's leader Kim Jong-un as "Rocket Man", an expression the U.S. leader used when they exchanged verbal spats amid heightening tensions in 2017.
Attending a NATO summit in London earlier this week, President Trump said Washington could use military force if it must, urging the regime and its leader to honor their agreement to denuclearize, referring to Kim as "Rocket Man".
Choe says such remarks should be diagnosed as what she called the "relapse of the dotage of a dotard", if any words "stoking the atmosphere of confrontation are used once again on purpose at a crucial moment as now."
She added that Kim Jong-un has not used any harsh words against President Trump in an effort to prevent the situation getting worse.
Choe's remarks come just a day after Pak Jong-chon, the Chief of the General Staff of the North Korean People's Army lashed out at President Trump in a separate release, saying the regime will also take "prompt corresponding action at any level", if the U.S. does indeed use military force against the North.
