"It is gaining diplomatic results", Mattis said.
"Hopefully it will all work out", he said. I have to say, Eddie, you're going to become extremely famous.
Trump tweeted: "Military solutions are now fully in place, locked and loaded, should North Korea act unwisely". Beijing has been remarkably quiet as US President Donald Trump and North Korea's premier Kim Jong-un have exchanged apocalyptic threats.
In North Korea, General Kim Rak-Gyom, the commander of the North's missile forces, dismissed Trump's "fire and fury" remarks as "a load of nonsense", according to Pyongyang's official Korean Central News Agency.
German Chancellor Angela Merkel said the escalating rhetoric was the "wrong answer" and saw no military solution to the crisis.
Asked if South Korea could feel assured of Trump's handling of the situation, Trump said he thinks it's "very happy", as was Japan. In the candid call, Trump asserted that the U.S. Pacific island territory was safe and called Calvo "a helluva guy".
Ba Dianjun, director of the Center for Northeast Asia at Jilin University, underscored that despite the mutual aid and cooperation friendship treaty between China and North Korea, Beijing will not come to help if Pyongyang attacks first. But in brief comments to reporters yesterday in California, he moderated his earlier tone on Wednesday, when he said North Korean aggression would lead to the "end of its regime and destruction of its people". "And we see this as a positive sign", he said.

Conflicting messages about how serious the United States is about a military confrontation with North Korea have also emerged.
There has been no indication that any actual attack on the Pacific island is imminent.
"And we assure our civilian populists, we assure the people that preparations are being made for any eventuality and we will inform communities that may be affected", Purisima added.
He also chided the North's closest ally, China, saying it could do "a lot more".
Some see Trump waging a game of chicken against North Korea, assuming that Kim will back down if his nation's existence is threatened by American military might.
