Let's assume NK gains a nuclear deterrent, that does not mean NK is suicidal. They aren't getting one to launch. Let's face it, we can always nuke them, that's always an option. And what kind of crazy would they have to be to attack the United States?
That's just suicide. They don't need the USA to commit suicide. They can slit their own throats any day they decide to. So, I'm afraid we ride this out and maybe some better opportunity will emerge before they have the deterrent. And on the upside
Trump won't go down as a mass murderer.
