H.R. McMaster delivered a stark warning to Kim Jong-un with an ominous message that Donald Trump will not rest until North Korea gives up its nuclear weapons.
The recently-appointed National Security Advisor (NSA) said the U.S. Navy aircraft carrier was one of a "full range of options" that the US had at its disposal to handle North Korea.
Last night, the US reversed the course of a warship and sent it to the Korean peninsula, with many experts claiming the move puts the US and North Korea are on a warpath.

A US official told the Reuters that Carrier Strike Group 1 would leave Singapore and move towards the western Pacific Ocean near the Korean Peninsula.
The move comes amid increasing concerns over North Korea's nuclear weapons programme.
North Korea said on Saturday the US strike against the Syrian regime showed that its decision to further strengthen its nuclear armed forces was "absolutely right."
Mr McMaster told Fox News Sunday: "The move is prudent.
"Korea has engaged in a pattern of provocative behaviour. This is a rogue regime that is a nuclear-capable regime."
