Majority of Iranians doesn't support Mullah. There is a reason why the regime is so oppressive.
Majority of Iranians actually do support Mullahs. Unlike Turkey, Iran did not/does not have an American made "deep state". Without overwhelming and substantial public support, Iranian government can not survive. There is a minority of people who do not like Mullah, but even most of these people who are against Mullahs accept the fact, that trying to bring down the government will only lead to more troubles and the only way they preach is evolution of system not, its dismantling. Only a small minority of this minority preach for overthrow of the government. And then only even a smaller handful of people among this minority of minority support and preach for overthrow of government by foreigners and with the help of foreigners.
On the other hand, in Turkey, you have "deep state" ruling a supposedly secular state. You have the military which in case of Turkey can only re-locate graves and overthrow its own government. And then you have a government which gains its popularity by preaching for a particular interpretation of Sunni Islam. And then you have Gulen movement which has taken over the roots of your state and society. And then you have ultra-nationalists whose sole purpose is to keep Kurds and non-Sunnis scared. And then you have ultra-religious whose purpose is to support Isis with permission of your religious government. And then you have violent communists/leftists.
Turkey is in a mess.
Erdogan is your Ziaulhaq.
It is only a matter of time, before things will implode in Turkey.
It is already running on borrowed time, both politically and financially.
The debt burden of Turkey and foreign investment in non-production sectors of economy (property, land etc) is high.
The bubble will eventually burst.
Then we can have the last laugh. As we have always had.
Iran is a country with a history of thousands of years. Many Ottomans, Pharaohs, British Empires, and Saddams came and became dust at Iran's feet.
What matters is who will have the last laugh.
Historical evidence says, it is always us. No need to doubt it.
