You make it sound like a easy task.. They are getting killed and put in prison. Iran's regime had build very effective fortifications for these types of protests and unrest. They know how to crack down on it, they do it by being as brutal as possible. The sad truth is that if not big portions of the population stands against the regime nothing will change. And unfortunately it's not enough what has happened to date.

The biggest issue with the regime falling is that we will see a new Libya. I don't think it will become better if the regime is removed unfortunately.
