thats what we all hopeNo, it won't happen. Simple answer.
I'm saying this because there's far too many law's and treaty's that at the end of it it'd mean the end. If any problems persist, the UN get involved and they try to solve them, such as Britain / America & Iran. If it was around the same time as WW2 then it would of started years ago, but it won't happen simply because of the fiasco in Iraq, back in the 1940's they wouldn 't really care about who or what they did, now they do and they have to.
that probably made no sense, but there would be no WW3 if things continue like this right now, even though they're unsteady - there is boundries.
Im 13 and im terrified about nuclear war PLEASE, someone, reassure me PLEASE. What are the chances of it happening?
