RAGING Kim Jong-un spat a stream of insults at Donald trump last night - calling him a "mentally deranged dotard" and a "rogue and a gangster".

But the North Korean dictator's colourful insults are just the latest in a long line of outright bizarre political put-downs thrown out by the brutal regime.

State mouthpiece KCNA has been dealing out hits against US and international politicians for years, perfecting a style that’s veered from jaw-dropping to shockingly racist.

In May Senator Cory Gardner called Kim Jong-un a "whack job" - and Pyongyang was not happy about it.

A statement said: "It is a serious provocation that Gardner, like a psychopath, dare to bear the evil that dares our highest dignity.

"It is America’s misfortune that a man mixed in with human dirt like Gardner, who has lost basic judgement and body hair, could only spell misfortune for the United States."

Former President Barack Obama also came under fire.

In 2014 North Korea branded him a "juvenile delinquent", a "clown" and a "dirty fellow" - and the shockingly racist: "(He) still has the figure of monkey while the human race has evolved through millions of years."

Obama, the KCNA statement said, was somebody who "does not even have the basic appearances of a human being" and, in a particularly vile statement, called him: "a wicked black monkey".

Earlier that year, an unidentified North Korean spokesperson called ex-Secretary of State John Kerry a "wolf donning the mask of sheep" who had a "hideous lantern jaw".

Kerry’s predecessor, Hillary Clinton, was described in 2009 as "by no means intelligent" and a "funny lady".

THE ORIGIN OF KIM'S 'DOTARD' INSULT According to the Oxford Dictionaries, a dotard is"an old person, especially one who has become weak or senile", while Merriam-Webster defines it as a "person in his or her dotage". The insult dates back to the 14th Century and was used by the poet Geoffrey Chaucer in The Miller's Tale. One line reads: "For certeyn, olde dotard, by your leave."

"Sometimes she looks like a primary schoolgirl and sometimes a pensioner going shopping," an unnamed North Korean source said.

The reclusive regime has also made former South Korean President Park Geun-hye a popular target, alternately naming her as a "senile granny", a "tailless, old, insane bitch", and "a traitor for all times".

On the last description, North Korea may have scored a late victory. Geun-hye was forced out of office amid a corruption scandal.

Kim Jong-un’s staff was no easier on former President George W. Bush’s administration: Bush was called a "hooligan" who looked like "a chicken soaked in the rain".

Vice President Dick Cheney was called a "most cruel monster and bloody-thirsty beast" and Defense Secretary Donald Rumsfeld was blasted as a "political dwarf, human scum or hysteric".
