You should understand that as much as you may disagree with the current Iranian government, they are holding your system and country together. Yes, there are some flaws in regards to how they go about their laws; but, without them, Iran would be another banana republic ruled by pro-westerner elites who would do every bidding the west demands.
You wouldn't have an Iran at all if it weren't for the Islamic revolution of 1979. What do I mean by that? Israel wouldn't have allowed any sort of nuclear development, missile development, etc, to progress.
From a Pakistani perspective, one who has lived both in the west and in Pakistan, you should cherish your current government. Whatever it is that you disagree with can be solved by other means.
Always look at the bigger picture.
I see Iran as a buffer between Pakistan and western domination. Iran, even though there are many policies of them I disagree with (in regards to India and supporting some Baloch separatists mainly), it is Iran that gives Pakistan a strong buffer against those that seek to truly extinguish Islam, particularly Israel & the west. Iran is doing its part before things take a dive for the worse. These protests going on should concern the whole world (as it is beginning to).
Iran is currently holding the opposition to the "system" in place along with Russia & China. But Iran is more so for the sake of Islam (as much as Sunni Muslims may not agree with this). Now Afghanistan (under the Taliban) is building another bridge unto this.
They've shown opposition to Israel and to the USA with their evil dictatorial policies.
All we need now is the revolution of Imran Khan - another pro-Islam person - that is going on in Pakistan to take fruit. This will truly seal the deal. While Iran may or may not fall with these protests, those east to Iran (Taliban and hopefully Imran Khan's Pakistan) will hold Islam's position the way it is meant to be held in the world.
