In stark terms, US tells North Korea it risks ‘massive military response’ after nuclear test

The United States has warned it could launch a “massive military response” to threats from North Korea following Pyongyang’s provocative detonation of what it claimed was a miniaturised hydrogen bomb.
The comments from Defence Secretary Jim Mattis came after US President Donald Trump called an emergency meeting of his national security advisers to discuss what was an unexpectedly powerful nuclear test said to exceed in magnitude the atomic bombing of Hiroshima, Japan.
