First thing you need to know is the government itself in Iran is nobody, Ali Khamenei has been enjoying full power and control for the past 30 years or so. Iran's president and minsters can only be appointed by Khamenei's approval.
With him being in power he needed a royal force to follow his ideology and shut down any voice of criticism, that's IRGC (Islamic Revolutionary Guard Corps).
IRGC and Khamenei control as much as 50% of Iran's economy, from telecom to oil. needless to say they don't answer to anyone, they don't pay any taxes and Khameni itself doesn't even do any interviews with the press.
I think majority of Iranians hate the current regime as much as i do, for one, It's not possible to change it democratically. One person has all the power in country and he made a powerful force to back him up.
every time Iranians want to change the country, Khameni unleash his dogs (IRGC) and they either kill all the protestors or arrest them and sentence them to long term prison. I've been shot and spent time in Iran's political prison (Evin), my crime? participation in peaceful protests (https://en.wikipedia.org/wiki/Iranian_Green_Movement)
> Would a return of the Shah be a positive thing?
Return of the Shah, reminds of me Russians who are envy of the soviet union time, because things were better at the time. I personally think democracy is the best way to go and no one person should have majority of the power.
> Do you have any fears of Israeli aggression, or would you support a peace deal
Enemy of my enemy is my friend, that's how I (and honestly majority of the people that i know) think of Israel. I think at the moment, Israel is the only country in the world stopping the regime from developing nuclear weapons and that's a good thing.
Iranians and Israelis historically have been friendly, Its only since this regime got the power that has changed, and i do understand why, because Iran has been threatening to wipe Israel off the map almost everyday.
It's not, Iran has been saying it very publicly:

These photos show the counters installed in every city in Iran, counting down how many down days left to destroy Israel. eg wipe it off the map.

I wouldn't go that far. Yes, Israeli Arabs technically have full rights. Yes, technically speaking they might be able to go to places non-Arabs "can't".
But that's being really "technically correct". I think for day-to-day living, Israeli Arabs effectively have a worse time living in Israeli than Israeli Jews (e.g. there is at least some racism, unfortunately, there are certainly differences in funding in e.g. Arab schools vs Jewish schools from what I know, etc).
