U.S. Defense Secretary Jim Mattis said on Saturday that he could not imagine United States ever accepting a nuclear North Korea, warning that its rapidly advancing nuclear and missile programs would undermine, not strengthen, its security.
Mattis has been at pains during his week-long trip to Asia to stress that diplomacy is America’s preferred course, a message he returned to after top-level military talks in Seoul on Saturday and the tense border area with North Korea on Friday.
Still, he warned Pyongyang that its military was no match for the U.S.-South Korean alliance, and that diplomacy was most effective “when backed by credible military force.”
“Make no mistake – any attack on the United States, or our allies, will be defeated. And any use of nuclear weapons by the North will be met with a massive military response that is both effective and overwhelming,” Mattis said.[contentcards url=”http://www.businessinsider.com/jim-mattis-nuclear-north-korea-dmz-2017-10?&platform=bi-androidapp” target=”_blank”]
