This is what trump said to australias prime minister recently
On North Korea, Mr Trump said if new "toughest ever" sanctions are unsuccessful, "we'll have to go to phase two".
"We'll have to see. I don't think I will exactly play that card, but we'll have to see," Mr Trump said.
"If the sanctions don't work we'll have to go to phase two and phase two may be a very rough thing, may be very, very unfortunate for the world.
"But hopefully the sanctions work.
"We have tremendous support all around the world for what we are doing.
"It really is a rogue nation. If we can make a deal, it will be a great thing. And if we can't, something will have to happen."
