North Korea and the United States seem to be reigniting the heated rhetoric that caused tensions between the two nations to tighten immensely. After president Donald Trump tweeted about the size of his nuclear button, North Korean dictator, Kim Jong-un, had a reply of his own.

North Korean state media called President Trump’s boast of having a bigger nuclear button than its leader Kim Jong Un the “spasm of a lunatic” Tuesday. North Korean propaganda has also dubbed Trump as a “loser” and a “psychopath” after the US president tweeted that his nuclear button is larger than Kim Jong-un’s and it actually functions.

North Korea’s official news agency (aka, state propaganda) described Trump’s tweet as the “the spasm of a lunatic,” according to AP. “Trump’s bluff is regarded by the DPRK (Democratic People’s Republic of Korea) as just a spasm of a lunatic frightened by the might of Juche Korea and a bark of a rabid dog,” said the report which summarized a commentary in the ruling party newspaper Rodong Sinmun. Juche is the official North Korean state ideology, often translated as “self-reliance.”

“The spasm of Trump in the new year reflects the desperate mental state of a loser who failed to check the vigorous advance of the army and people of the [Democratic People’s Republic of Korea] … He is making [a] bluff only to be diagnosed as a psychopath,” it added.

Trump’s tweet came a day after Kim said in a speech: “The United States should know that the button for nuclear weapons is on my table,” according to the Associated Press. Kim claimed the weapons were capable of reaching the entire U.S. mainland. It followed an escalating war of words between Trump and Kim, amid global concerns that nuclear war could break out.  As we wrote in a previous report, the US military is already preparing for a war with North Korea, albeit silently.

According to the Washington Post, in their Tuesday responses to the tweet, North Korean media also appeared to address speculations over President Trump’s mental health which were raised in the controversial “Fire and Fury” book. Trump has rejected the claims made in the book, and has boasted about being “like, really smart” and a “very stable genius” in response.
