If North Korea continues with its plan to fire several missiles at the United States territory of Guam, Defense Secretary James Mattis said then “we’ll take you out.”

Mattis surprised reporters with an appearance after the weekly briefing on Monday. The Secretary of Defense said if North Korea does fire a missile, his department will know “within moments” where it is headed.This comes after North Korea  warned it was considering a plan to launch four ballistic missiles to land in the sea just outside Guam.

Asked how the U.S. would respond, Mattis initially declined to say. But when pressed, he said that if U.S. radars and other detection and tracking systems determine that a missile was going to fall into the sea, short of Guam, then the matter would be taken to President Donald Trump for a decision on how to respond.
