President Trump took to Twitter on Friday morning to warn North Korea that military solutions are "fully in place, locked and loaded" as tensions continue to escalate.
Trump then strengthened his rhetoric again on Thursday, saying "maybe that statement wasn't tough enough".
Trump added: "He has disrespected our country greatly". Australian Prime Minister Malcolm Turnbull said today his government would back the USA if North Korea attacked. After North Korea disclosed plans to fire missiles over Japan to land near the US Pacific territory of Guam, Trump said the move would prompt "an event the likes of which nobody's seen before".
As North Korean ballistic missiles are liquid fueled, they take some time to prepare for launch, unlike solid fueled ICBMs deployed by the United States and Russian Federation that can be launched on command.
He said North Korea "should be very, very nervous".
Trump also predict that the newest sanctions against North Korea, passed by the UN Security Council over the weekend, will likely be "not as effective" as intended.
Meanwhile, China urged Washington and Pyongyang to calm but warned through Global Times that Beijing will remain neutral if the USA is attacked and decides to launch a counterattack.
North Korea said it has drawn up plans to launch four missiles near the small island of Guam, a USA territory and military hub.

Trump has attempted to leverage China, North Korea's only major ally, to apply more economic pressure on the isolated regime.
