(NBC NEWS) LONDON — After years of North Korea thumbing its nose at the international community, on Friday Defense Secretary James Mattis appeared to signal enough was enough.

“Right now, [North Korea] appears to be going in a very reckless manner … and that has got to be stopped,” Mattis said at a press conference in London.

He didn’t give any details about how the administration of President Donald Trump plans to deal with the reclusive nation, which, under Kim Jong Un, has drastically increased its missile and nuclear-testing program.
