President Trump's language on North Korea, which he has previously threatened to destroy with "fire and fury," is not inflammatory, national security adviser H.R. McMaster said Thursday.

"What's inflammatory is the North Korean regime," McMaster told reporters at the White House as he laid out the priorities for Trump's upcoming, 12-day trip to Asia.

McMaster declined to say whether Trump would adjust his rhetoric about Kim Jong Un's regime while visiting China, South Korea, Vietnam, Japan, and the Philippines.

"The president will use whatever language he wants to use, obviously," McMaster said. "I don't think the president really modulates his language. Have you noticed?"

Critics have said Trump risks inflaming tensions between Washington and Pyongyang by threatening North Korea with total destruction each time the regime flexes its military muscles. North Koreans have accelerated their tests of missiles and nuclear weapons in recent months as they approach the ability to fire a nuclear weapon onto the U.S. mainland.

McMaster said one of the major goals of Trump's visit to Asia will be to rally allies to pursue the "complete, verifiable and permanent denuclearization of the Korean peninsula."
