I believe that no country will ever directly attempt to use a nuclear weapon against another country that also posses that weapon. Even if a mad dictator would want it, I have faith that his generals are clever enough to not set their country and our world to doom.
Also, China might be friendly with Korea, but I doubt China would actually be involved in a conflict if N.Korea acts stupid
Also, no WWIII close, sorry bro.
I believe OBama, and future American presidents will be more concerned about USA reputation than Bush, so UN will have some impact.
I believe both Iran and North Korea are more or less the same. None really want to strike someone with Nuke (IRan hates Israel, but will not strike first). They just want some attention, some strenght on the international market.
Countries should act like us, Canada. No need for weapons, no need for nuclear weapon (I’ve read somewhere that Canada is probably a country that can build a nuke very quickly due to our numerous nuclear reactors and our technology). I suppose international news never mention us, its like we don’t exist. Except when baby seals get hunted. That’s the only time you will hear about Canada
