Donald Trump calls Kim Jong-un a 'Rocket Man on a suicide mission' in UN speech

Elton John and Bernie Taupin wrote the song "Rocket Man" almost 50 years ago.

But the song, which tells of the melancholy and loneliness experienced by an astronaut “on such a timeless flight”, has been getting plenty of publicity in recent days courtesy of Donald Trump, who has chosen it as his nickname for North Korean leader Kim Jong-un.

On Tuesday, in his address to the UN General Assembly, Mr Trump focused much of his attention on the East Asian nation, using language that represented a major departure from diplomatic convention.

During a bellicose speech, the US President threatened to “totally destroy” North Korea if it did not step aside from its nuclear weapons programme.

“Rocket man is on a suicide mission for himself and his regime,” Mr Trump said. He said of the US: “If it is forced to defend itself or its allies, we will have no choice but to totally destroy North Korea.”

During his first speech to the body, Mr Trump adopted a puglistic, nationalist approach.

"I will always put American first. Just like you, the leaders of your countries, should and always put your countries first. The U.S. will forever be a great friend to the world and especially to its allies,” the Republican president said.

“But we can no longer be taken advantage of or enter into a one-sided deal in which the United States gets nothing in return."

Not everyone was there to hear Mr Trump’s words. While the North Korean delegation was seated just yards from where he spoke, its Ambassador to the UN, Ja Song Nam, left the room shortly before the US President entered the room.
