On nukes: I believe that they would only go as far as build them (if even that) and start threatening other countries.
The reason they will probably never use them is that if they do, they're pretty much screwed - the US and NATO will finally have a clear reason to start a war with them and they'll go the way of Iraq for sure. They don't have the military power to oppose any serious attack from NATO, at least from what I can see.
Russia and China stepping in would be the only possible game changers, but I don't see a reason for them to side with Iran as it is now, either...
P.S. Is it me or downvoting seems flawed here - one downvote and the comment is out of sight?
