That's not what I'm seeing.
Why would "the people" be burning hundreds of mosques, ancient libraries, police stations, buses and civilian homes?
How have over 100 police been killed so quickly by "organic" protests?
And why is Israeli media reporting that they have agents on the ground instigating violence?
I wouldn't know why they are burning things. I suppose they burn the religion of peace symbols of their oppressors.
I imagine that Israel supports a regime change in Iran, but I don't think that they can run this on their own. They probably support whatever goes on with covert agents.
Since little gets out of Iran let's not speculate any more. :)
