An Arab Spring would be nice to happen in Iran. If the protests over Ahmadinejad's re-election in 2009 showed us anything, there's already cracks in the foundation of "The Islamic Republic".
The country itself is secular just the government isn't
Agreed on both counts. Most of the Iranian immigrants I have met in the USA left explicitly because they disliked the government there and wanted greater freedoms.
I don't believe for one minute that the youth of Iran really wants to go to war with the USA or Israel, nor do they want to live under a theocratic government. Remember also that Iran is, in demographic terms, a "younger" country than the USA and most of Europe, the median age being only about 27. So frankly, I wouldn't be terribly surprised if the younger generation rose up in rebellion against Khamenei and his people.
