They will just have to die by the nukes then.
The gun controlling liberals are completely fine with foreign nation, that is known to torture their own citizens for mere disagreements in opinion, having a nuke.
For the record I am not saying that NK should necessarily be invaded, but if insane people having guns is a bad idea... surely letting insane people have nukes is even worse idea?
Works on the assumption the leaders of NK are truly "insane", and not just holding different values than you do.
It's a horrible regime, but the main reason they want nukes is because nobody messes with a country that has nukes.
And when someone insists we should nuke someone because they have weapons we don't like, I have to wonder who the crazy ones are.
