I think that above all, Iran shows our inability in the real world to stop any reasonably sophisticated nation from acquiring nukes if it really wants them. However, it doesn't follow that nations should be allowed to acquire nuclear weapons with impunity. It's a shame we had to start with all the blustering and threats -- which I see as having been totally counter-productive -- but we can now settle down and impose a nice long, dreary regimen of embargoes and sanctions. Let the next Iran see the price tag. So skip all the arm-waving about how Israel already has nukes, Iran is the incarnation of evil, nuclear weapons will destroy humanity, etc. How do we make getting nuclear weapons prolonged, expensive, and unpleasant?
