"I will tell you this, North Korea better get their act together or they're going to be in trouble like few nations ever have been in trouble in this world", Trump said. "They're bullying us, because they're used to bullying us, because we've had punks running America ... we've had think-tankers and defense contractors, but we've never had - in recent times, anyway - someone willing to stand up for America".
North Korea and its totalitarian leader, Kim Jong Un, have again been thrust into the center of global media attention this week after its government threatened to fire missiles at a United States pacific territory.
It prompted Trump to warn that he would unleash "fire and fury" on North Korea if it did not stop its threats to the US. "Then, what will you say?"
Thousands of youths, workers and trade union members gathered in the capital Pyongyang and around the country for rallies, saluting pictures of the country's former dictators, Kim Il-sung and Kim Jong-il.
In an apparent response to Trump's tweet, a statement issued by North Korea's official KCNA news agency claimed the president is "driving the situation on the Korean peninsula to the brink of a nuclear war".
U.S. President Donald Trump and the Kim regime now seem to be locked into a war of words.
The United Nations Security Council, with encouragement from the US, voted unanimously at the beginning of August to impose new sanctions against North Korea in retaliation for the regime's recent intercontinental ballistic missile tests. I mean, his rhetoric might make Kim Jong Un think that he needs to strike first.
