President Trump and the leader of North Korea, Kim Jong un, have traded insults publicly, with the latest juvenile interaction suggesting that a mutually acceptable solution to North Korea's nuclear weapons programme is still some way off.
Trump's tweet was part of a series of tweets that included China's plan of "upping the sanctions" against North Korea and how Chinese President Xi Jinping wants to "denuclearize" the country.
Trump was responding to North Korea calling his South Korea speech days earlier: "reckless remarks by an old lunatic".
DONALD Trump has lashed out at Kim Jong-un saying he would never call him "short and fat" before saying he was trying "so hard to be his friend".
"Why would Kim Jong-un insult me by calling me 'old, ' when I would NEVER call him 'short and fat?'" Trump tweeted Sunday after arriving in Hanoi, Vietnam. His comments came after Trump threatened in his maiden United Nations address to "totally destroy" the country of 26 million people if the United States were threatened. I have never been more certain of anything. And do not try us.
Jouas, formerly deputy commander of US Forces Korea, said the near 30,000-strong US forces stationed in the neighboring South would struggle to counter the North Korean Army, which the country claims nearly 5 million people have volunteered for.
And in a warning directed at young dictator Kim, he said: "The weapons you are acquiring are not making you safer".More news: TripAdvisor targeting sexual assault with new feature
Utilising Twitter's new 280-character tweet length Mr Trump gave his thoughts on a range of subjects, from relations with Russia, China's efforts to rein in North Korea, and a sarcastic message about his bid to make "a friend" of Kim.
"Strange things happen in life".
Addressing a press conference later, Trump declared his belief that it was possible for the two leaders to be "friends".
"If it did happen it could be a good thing I can tell you for North Korea, but it could also be good for a lot of other places and be good for the rest the world".
"Together we have in our power to finally liberate this region and the world from this very serious nuclear menace, but it will require collective action, collective strength and collective devotion to winning the peace", Trump said.
"Every step you take down this dark path increases the peril you face".
