Donald Trump’s bellicose rhetoric aimed at North Korea has pushed the US and the communist dictatorship to the brink of nuclear war, according to the North Korea’s foreign minister.

“By his belligerent and insane statement at the United Nations, Trump, so to say, lit the fuse of war against us,” Ri Yong Ho told Russia’s state-run news agency TASS.

“We need to settle the final score, only with a hail of fire, not words.”

During his maiden speech to the UN, Trump mocked Kim Jong-un, dubbing him “Rocket Man” and warning that the US may be forced to “totally destroy” the rogue nation, the New York Post reported.

 “If the righteous many do not confront the wicked few, then evil will triumph,” Trump said. “Rocket Man is on a suicide mission.”

Ri’s threats came a day after a pair of US bombers for the first time conducted manoeuvres over the Korean peninsula with the South Korean air force, and followed stepped-up sabre-rattling by the president on Twitter.

Trump has repeatedly suggested military action was the only solution to the North’s belligerence and growing nuclear weapons and missile program.

“Presidents and their administrations have been talking to North Korea for 25 years, agreements made and massive amounts of money paid hasn’t worked, agreements violated before the ink was dry, makings fools of US negotiators. Sorry, but only one thing will work!” he tweeted on Saturday.

“Our country has been unsuccessfully dealing with North Korea for 25 years, giving billions of dollars & getting nothing. Policy didn’t work!” he added in another tweet two days later.

North Korea has launched two missiles over Japan and conducted its sixth nuclear test in recent weeks as it advances quickly toward its goal of developing a nuclear-tipped missile capable of hitting the US mainland.
