Nothing is going to happen, at least not in this generation of the government. Just wait 20 +/- years till all these uneducated morons have died out and replaced by educated members.
Every Iranian I met is super nice and friendly. They stay away from trouble and don't give a damn about non-sense. Almost all of them were professional in their behavior as well, not barbaric hooligans.
Too many pride issues on both sides. Its disgusting. Hopefully the next generation (in the government) are opened minded and clearly see what the real problems are.
If ISIS wins anything its bad news for the world because it will give other terrorist organisations hope that they can also win, which will be troubling.
The way the police handled this situation was pathetic. When I saw the videos of what the police were doing to the people it was disgusting. These men had no humanity in them.
