The US President made the remarks directly to the North Korean dictator during his historic speech before South Korea’s National Assembly earlier today.
It comes as the two firebrand leaders are engaged in a war of words over North Korea’s missile tests and nuclear programme.
Trump said: “I also have come here to this peninsula to deliver a message directly to the leader of the North Korean dictatorship: The weapons you are acquiring are not making you safer.
“They are putting your regime in great danger. Every step you take down this dark path increases the peril you face.
“North Korea is not the paradise your grandfather envisioned. It is a hell that no person deserves.”
The President also highlighted the failure of the North Korea’s economy since it split from its southern neighbour.
He said: ”When the Korean War began in 1950, the two Koreas were approximately equal in GDP per capita, but by the 1990s South Korea’s wealth had surpassed North Korea by more than 10 times. And today the South’s economy is over 40 times larger. You’re doing something right.
“North Korea is a country ruled by a cult. At the centre of this military cult is a deranged belief in the ruler’s destiny to rule as a parent protector over a conquered Korean Peninsula.
“The more successful South Korea becomes the more successfully you discredit the dark fantasy at the heart of the south Korean regime.
“Yet despite every crime you have committed against God and man, we are ready to offer a path towards a much better future.
“It begins with an end to the aggression of our regime, a stop to your development of ballistic missiles and complete verifiable and total denuclearisation.”
The US President also issued a chilling warning to North Korea as he declared the US would not be intimidated by Kim Jong-un’s intercontinental ballistic missiles (ICBMs).
The firebrand Republican said: “We will not allow American cities to be threatened with destruction. We will not be intimidated.
“And we will not let the worst atrocities in history be repeated here, on this ground we fought and died to secure.
“The world cannot tolerate the menace of a rogue regime that threatens it with nuclear devastation.”
Earlier Trump attempted a visit the South’s demilitarised border (DMZ) with North Korea but the plans had to be scrapped a few minutes before the President was to land in Marine One.
According to White House press secretary Sarah Sanders the plan had to be abandoned due to “poor weather”.
She added the President is “pretty frustrated” that he had to change his plans.
The visit would have marked a historic step by Trump as it would have been the closest the President as been to Kim Jong-un with whom he has been engaged in an escalating war of words.
The White House said Trump’s trip to the DMZ had been planned well before he left for Asia, but it was kept secret due to security concerns.
