They could smuggle these in over our open border or just keep them in international waters or Mexico for that matter. Hell we launched an ICBM from an airtransport during the Nixon years. And this is Chinese supplied weaponry....who are we kidding that the Norks could produce all this stuff by themselves. The Chinese are make Trump sweat....its time Trump makes them bleed.
Sure, if China gets into the act it could make things more interesting. But even little nukes are comprised of things that will ping back to a particular kind of scanning ray.
Kim is getting dangerous because he’s actually believing his own buffalo. What happens when he gets a notion to nuke Beijing?
It will be fascinating if Trump - who ran on limiting our foreign interventions - got us into a hot war with China and North Korea in the first year.
