Trump 'will take action' to end any North Korea threat to US: top security adviser

National security adviser said Trump won't allow North Korea threat to continue.

North Korea rolled out ballistic missiles and other weaponry at a huge parade Saturday and later in the day, at 5:21 p.m. ET, made a failed attempt to shoot off a missile, which exploded immediately after launch.

McMaster said the launch "fits a pattern of provocative and destabilizing and threatening behavior on the part of the North Korean regime."

"I think there's an international consensus now, including the Chinese and the Chinese leadership, that this is a situation that just can't continue. And the president has made clear that he will not accept the United States and its allies and partners in the region being under threat from this hostile regime with nuclear weapons," said McMaster, who spoke from Kabul, Afghanistan.

But the president's tweet indicated an openness to U.S. intervention if China doesn't deal with the nuclear threat posed by the isolated country.

"If they are unable to do so, the U.S., with its allies, will!" the president said.

And Sunday morning, Trump tweeted in defense of his decision not to label China a currency manipulator, saying "they are working with us on the North Korean problem."
