In general I agree with you however just tell me why shouldn't North Korea be allowed to test weapons if after all the US, UK, France, China, Russia did exactly the same thing 25-50 years ago ? Is the US willing to ban all nuclear weapons including their own ?
No, because its not one guy with his hand on the button.
I'm not saying they have to govern the way we do, but, checks and balances should be part of every government. Lets say this guy is sane now, but then goes crazy as he gets older (which, isn't that far-fetched... I mean, when you get older you do have a chance of going a bit nuts) ... who's gunna tell him no when he wants to play with the nukes on his last years? His cheerleading squad? The people who are starving but have to listen to a chart topping song that has been #1 forever there...that is...about..."HIM" .
I'm not saying I have the true picture either, but, I'm a little more trusting in places like the UK, or Spain, or France that have open communication and a system of government that monitors itself or at least attempts to.
