The Hermit Kingdom has long threatened violence against the President and the US, once claiming they would wipe the America "off the face of the earth".
Now a statement from state propaganda mouthpiece KCNA has warned Trump could "bring a war to the Korean peninsula" by visiting South Korea next month.They went on to praise protests in the South against Trump’s visit, telling clueless citizens that people marched in the streets opposing the US President.
But images from the protests show groups of no more than 10 people taking part in the rallies, which used slogans coined by Kim Jong-Un’s regime.
The KCNA missive also branded the US President a "war maniac" and a "lunatic".
Trump could enter North Korea in a direct provocation to Kim Jong-un if he visits the DMZ during his trip to Seoul next month.
Local news reports have suggested the US president could visit the heavily fortified border which it is feared North Korea will view as a threat.
Despite rising tensions between the neighbours the DMZ remains a popular destination that sees many tourists technically passing into North Korea by entering a hut where the armistice was signed.
In 1983 President Ronald Reagan, who Trump has long admired, took a tour of the area.
Now there have been calls for Trump to carry out the provocative trip as a show of strength.
But concerns have been raised the move could provoke retaliation from the isolated dictatorship amid soaring tensions on the Korean Peninsula.
Sue Mi Terry, a former Korea analyst, said: "They're seeing almost everything as a threat.
"They already see him as a very provocative person.
"Anything that he does will be continually seen that way."
The 160-mile long border divides the Korean peninsula from coast to coast.
It is one of the most built up military borders in the world with a million soldiers standing guard, millions of landmines and conventional artillery.
Former assistant secretary of state for East Asian and Pacific Affairs Daniel Russel said: "The DMZ functions as a kind of amplifier.
"The message takes on a more martial and ominous tone when it comes out of a military command post on North Korea’s doorstep."
imo, the only way President Trump should visit to the DMZ is as the victorious Commander-in-Chief.
