NK launching a nuke, hitting a target and detonating are all big IF’s. It would almost take a miracle. Getting it off the launch pad is a big if and if it doesn’t work, you are in a world of hurt.
I’m surprised the Norks haven’t accidentally nuked themselves.
Now that would be the best outcome of a bad situation, except no one in the world would believe we didn't do it and what the hell!? our government just might say, "no comment," and DJT might smirk just a tad.
