Those were among a series of playground-type slurs the leaders of the two nuclear-armed states hurled at each other, setting the world on edge.
Last August, after US media reported Pyongyang had successfully miniaturised a nuclear warhead to fit into a missile, Trump warned Pyongyang not to threaten the US or it would face “fire and fury like the world has never seen.”
Kim had earlier compared comments by Trump to the bark of a “rabid dog,” and Trump derided Kim as a “sick puppy” – before the apparent outbreak of puppy love.
Trump met Kim in Singapore in June for the first-ever summit between the two countries that have never signed a peace treaty.
The summit led to a warming of ties and a halt in Pyongyang’s missile launches, but there has been little concrete progress since.
North Korea’s foreign minister Ri Yong Ho on Saturday told the UN there was “no way” that his country would disarm first as long as the US to push for tough enforcement of sanctions against Pyongyang.
