It's late here and maybe I am just too tired, but I am unable to figure out where you think the legitimization to blow up a North Korean reactor - correct me if you would not actually support this, you never said this, I just assume this based on what you wrote - would come from. I am not even sure whether we are really disagreeing. You said that you have no trust in their chain of command and technology and that may be valid reasons to not want them to have nuclear weapons, at least if we manage to make that judgment objective and I will grant you that we could do so. But were does the legitimization to enforce this desire with force against a sovereign country come from? It can't just be that NATO, Russia, and China want it, that would just be law of the strongest and would therefore be exactly the reason why North Korea would want their own nuclear weapons.
