Iran joined in? Interesting.
It is an extremely naive and bad idea.
What is going to stop one country from manufacturing nukes anyway and holding the world hostage?
That's the position of the nuclear powers and NATO I believe, that you have to somehow make sure that nobody decides to make nukes anyway and have it be enforceable with razor AND needle sharp teeth.
It's also kind of the problem with the last stage of nuclear disarmament, you have to really, REALLY, trust the other side to dismantle the very last nukes because, well, you don't want to end up removing yours and have the other side cheat or change their mind at the last second.
Don't get me wrong, I'm totally for nuclear disarmament, there's just logistical and enforcement problems that have to be solved first.
It may seem naive and the nuclear powers definetly have a point, especially regarding NK, but the idea itself is a good one, and gotta start somewhere. They haven't gotten to figuring out how to enforce it yet and that's the next step. The hard part is making sure the enforcement actually has teeth.
Anyways, I wonder what NK actually would think of that? They'd proabably have the US make some concessions first. Then again, it'd completely disrupt their sole means of regieme survival.
