U.S. President Donald Trump has stated, in a tweet, that Washington's military solutions are "fully in place, locked and loaded" to deal with North Korea, should it act "unwisely."
This remark is the latest in his string of threats to the regime.
Speaking at a press conference on Thursday, Trump warned Pyongyang that it will be punished if it launches ballistic missiles toward Guam.
"Let's see what he does with Guam. He does something in Guam, it will be an event the likes of which nobody has seen before, what will happen in North Korea.
Reporter: Is that a dare?
"It's not a dare. It's a statement, has nothing to do with dare. That's a statement."
Trump also said that his controversial "fire and fury" comments from Wednesday were perhaps "not tough enough" and warned that Pyongyang should be nervous.
He also did not rule out a pre-emptive strike, although at the same time he did not rule out negotiations either.
He said he would like to see a nuclear-free world, but until all countries, including Russia, China and Pakistan get rid of their nuclear weapons, he pledged the U.S. would remain "the most powerful nuclear nation on earth by far."
Such boisterous rhetoric from a U.S. President is unprecedented, but from North Korea, it's much more familiar and Pyongyang continued its usual verbal attacks on Trump and the U.S. on Thursday.
After calling Trump someone 'bereft of reason', and his threats 'a load of nonsense' the day previously, the regime's state media warned the U.S.'s reckless behaviour will lead to its mainland being reduced to ashes.
Trump's Defense Secretary James Mattis, tried to be more careful saying that the Pentagon did have military options at hand, but finding a diplomatic solution was still its top priority warning of the consequences of war on the Korean Peninsula.
"The tragedy of war is well enough known. It doesn't need another characterization beyond the fact that it would be catastrophic."
However, with neither Trump nor Pyongyang backing down, it looks like the war or words will not end anytime soon.
