The geography of Tehran is a death trap in a nuclear attack... the mountains will reflect and radiate the blast right back into the city, and should be fairly mild on the regional fallout [I bet the founders of the city never considered THAT military option]. There are 18 major populations in Iran. Israel has hundreds of nukes [as we all know] and it stands to reason Israel also has submarines which can launch these from any location on the globe. President Mahmoud Ahmadinejad truly hates his own people. - Godspeed to all the non-Muslims/righteous Gentiles evading the area.
