Thank you for the note, I hadn't heard this!
I'm about as opposed to war as you can get. Nuclear weapons are terrible, and I hope that they are never again deployed.
That said, I'm no fan of the UN, and I am highly suspect of anything they try to do. It is not a peaceful organization, and they have caused as many problems as they have solved. Their attempt at banning Nuclear weapons is probably just a political move, and I highly doubt that Kim Jong-Un will disarm at their polite request, since the threat of nuclear retaliation is the only reason NK is even still a thing.
There is no easy solution to this mess, but there is a lot to be said for the US and UN minding their own business.
