Nuclear Weapons

I don't really have a problem with articles that attempt to explore these types of questions rhetorically, but, taken at face value, the question "Is A Bigger 'Nuke Club' Inevitable?" is pretty silly. Fast forward 100 years from today and does it even seem remotely possible that any country who wants nukes won't have them? Is there any doubt about this at all? If Iran wants nukes, the simple fact is that they are going to get them. One more reason, I suppose, that senseless saber-rattling ought to quickly become a thing of the past.
