They are seeking freedom from corruption, and freedom from mostly elderly and certainly fundamentalist mullahs who are intent on denying Iranians the ability to progress and function as a modern secular society.
Iran is largely a very youthful country. The internet has made them well aware of the opportunities available to other muslim countries around them, such as the Gulf States, Iraq and Turkey - not to mention in the USA and Europe (where a fair number of Iranians have traveled).
I think the mullahs are finding it hard to keep them down on the farms, after they’ve seen Paree.
So what’s their “exit strategy”? I’m seeing a lot of yelling, but no indication of anything ready to replace the mullahs. The guy they’re hollering for isn’t much different from Ahmadenijad, and was on the ballot because he’s acceptable to the mullahs.
