NK isn't attacked, because SK cities are in range for conventional rockets. I'm not sure how much the nuclear capabilities add to that.
Let's hope NATO doesn't get compromised, else I see 30 new nuclear programs starting soon.
We all hooray (well, some of us) the "good" countries having nukes, to bring peace and stability. But it only takes one funky election to get a crazy person in charge of such "good" nukes. And if you 10x the number of nuclear powers, that's 10x more shots at that.
I don't intend this as a drive-by zinger, far from it, but I think you're being hopelessly optimistic. Every country with the science and engineering muscle to make it happen will be pursuing a nuclear program. NATO, former Warsaw Pact, some assholes who managed to cobble together a broadly recognized country by virtue of force of will, you name it. They're all going to be seeking to create nuclear weapons.
Also, you probably mean "unleash".
I do disagree with your premise that Gaddafi’s death was a natural consequence of the Western intervention. Whilst watching the events unfold at the time, I’d say he would be ousted and killed irrespectively of any intervention — either by the populace or by the various factions vying for power.
Seoul is in artillery range of the border.
