US will launch 'massive military response' to NKorea threats:

The United States will launch a "massive military response" to threats from North Korea, Secretary of Defense Jim Mattis said today.

He spoke after President Donald Trump met with his national security advisers following a test of what Pyongyang said was a hydrogen bomb able to fit atop a missile.

"Any threat to the United States or its territories, including Guam, or our allies will be met with a massive military response, a response both effective and overwhelming," Mattis said.
