Mr McMaster, who serves as President Trump’s National Security Advisor, said the US was ready to respond to North Korea’s aggressive rhetoric with “all capabilities available.”
He said: “What the President has done is clarified in all of his discussion and statements on North Korea, our determination to ensure that North Korea is unable to threaten our allies and our partners and certainly not the United States.
“The President recognises that we’re running out of time (to deal with North Korea) and will ask all nations to do more.”
President Trump is expected to reiterate his view that North Korea is a threat to the entire world during his diplomatic trip to Asia.
Mr McMaster continued, saying that now is the time for a “really concerted effort” to resolve the North Korea crisis without resorting to military action.
Speaking at the White House, he continued: ““It would be irresponsible not to talk about the potential for military efforts within the alliance. The reason why that topic must be on the agenda is because of the behaviour of this rogue regime and the threat that Kim Jong-un poses.”
But South Korean intelligence found the rogue nation is ready to carry out yet another nuclear test despite suffering major damage to its main testing facility in Punggye-ri.
Seoul’s National Intelligence Service said satellite images showed fervent activity taking place around a missile research facility in Pyongyang.
The intelligence agency said: “There is a possibility of a new missile launch given the active movement of vehicles around the missile research institute in Pyongyang.”
North Korea has been ramping up their threats toward the US picking up the pace with its testing of nuclear weapons in recent months.
Recent tests in early September at Punggye-ri registered as a 5.7 magnitude earthquake by the South Korean government.
A senior North Korean diplomat also said the United States should take threats of a possible atmospheric nuclear test over the Pacific Ocean “literally.”
