It's unlikely that Korea or Iran has the leverage to start a global war.
Even if either decided to start throwing nukes, it wouldn't start a global war. No one would back those regimes, and they would be pounded into dust within days or even hours if there was a nuclear strike. Who's gonna get NK's back? The Chinese? Unlikely. China would risk economic meltdown, and for what purpose?
The only way a world war will happen is if two or more major entities begin to fight amongst eachother:
China
US
Russia
EU
India
Otherwise, it will only be a localized conflict. I don't know if we'll fight another world war, but I feel that whatever is fought may be more economic than militaristic.
Back from the dead, I'm afraid.
