Comment: you guys are not going to like this comment, but I think nuclear disarmament is not possible. The US and russia will not even destroy their stockpile of cluster bombs. You think they will give up nukes? No way. Every nation aspires to getting a nuclear bomb. Why? Because nations with nuclear weapons do not get "regime changed", like Libya or Iraq. You may hate N Korea, but you won't be invading it because they can nuke south korea now if such an attempt were to be made.
