Mattis warns: U.S. "will never accept a nuclear North Korea"

SEOUL- 28 October 2017: U.S. Defense Secretary Jim Mattis said on Saturday that the United States would never accept a nuclear North Korea, warning that its rapidly advancing nuclear and missile programs would undermine, not strengthen, its security.

"Make no mistake - any attack on the United States, or our allies, will be defeated. And any use of nuclear weapons will be met with a massive military response that is both effective and overwhelming," Mattis said in prepared remarks after defense talks in Seoul.
