Donald Trump rejects diplomatic solution with North Korea's 'Little Rocket Man' saying 'we'll do what has to be done'

Donald Trump has appeared to dismiss the possibility of reaching a diplomatic solution with North Korea to curtail its nuclear weapons programme, saying: “We’ll do what has to be done.”

In one of a flurry of tweets published from his golf course in New Jersey, Mr Trump questioned outreach by US diplomats and officials in Pyongyang - the existence of which had been revealed over the weekend.

Speaking at a press conference in Beijing, Secretary of State Rex Tillerson said the US had direct lines of communication to North Korea, and that his immediate goal was to “calm things down” as the East Asian nation has stepped up its testing of missiles and nuclear payloads, and the US has intensified its sabre-rattling, with Mr Trump telling the UN that the US may be forced to "totally destroy" North Korea.

We are probing, so stay tuned,” Mr Tillerson told reporters, according to Reuters. “We ask, ‘Would you like to talk'. We have lines of communications to Pyongyang. We’re not in a dark situation or a blackout. We have a couple of direct channels to Pyongyang. We can talk to them. We do talk to them. Directly, through our own channels.”

He added: “We've made it clear that we hope to resolve this through talks. I think the most immediate action that we need is to calm things down. They’re a little overheated right now, and I think we need to calm them down first.”

On Sunday morning, Mr Trump seemed to pour cold water on the efforts of America’s most senior diplomat.

Whether it was part of a strategy to confuse and disorientate North Korea was unclear, but Mr Trump suggested diplomatic efforts had little chance of success. Without referring specifically to a military operation, the President said the US was ready to handle the situation by means other than direct diplomacy.

"I told Rex Tillerson, our wonderful Secretary of State, that he is wasting his time trying to negotiate with Little Rocket Man,” he said. “Save your energy Rex, we'll do what has to be done!”

During his first speech to the United Nations General Assembly, Mr Trump repeated his use of the nickname “Rocket Man” for North Korean leader Kim Jong Un, and said the US was ready to totally destroy his country if it threatened the US or its allies.
