Trump made the remarks after a meeting on workforce development with US Ambassador to the UN Nikki Haley and Secretary of State Rex Tillerson. “I hope they are going to fully understand the gravity of what I said.

He also blamed his predecessors for discord in the Korean peninsula, saying that the “current rhetoric is an extension of past failures” and he has no choice but to respond to the rogue tion, CNN reported.
