200 odd warheads will not be produced undetected. I doubt they can even produce a rubber boat without beeing monitored.
It's cetainly not close to that finish line because I haven't heard the israely F-16s running warm and I suppose Iranians will not spread their nukes to people they where at war with only some years ago.
Nuclear terrorsim will get more likely IF Apeboy get's his toys. But he will not. I just hope we don't have to bow to his demand and bomb that country.
And Iran will spread its nukes to anybody who will use them against Israel and America. They think 50 years of nuclear war by proxy will dethrone the modern west. That is their grand strategy. It is also China's grand strategy, you can read it in documents produced by their military academies. And Iran is an instance of it.
