Choosing one time does not mean that people have lost their right to change their opinion and now Wilayat system will be kept imposed on them for the next thousands of years.
That is why there are elections every few years to determine the people's choice. This right of people's choice has been usurped by the conservatives in name of different kind of lame excuses.
as I said, first you give this right at least for once to your people, then come and ask us for yearly constitution elections!
Other countries are far better in respecting the choice of their people by allowing them to go to the polls every few year.
Iranian elections are more than any other country. also we don't allow money oriented campaigns like those in corrupted western countries.
And people of other countries have also got the right to choose their system (Secularism) and the constitution. They are better than Iranian system while they provide open choice to the people to change the constitution (or even the system) through the parliament.
give me one example in which a country has allowed it's people to choose the type of system.
you can't, cause there is none.
And lecture is necessary to the conservatives while they are unable to see the reality that Reformists (who are traitors in their eyes) are getting more than 50% votes, while conservatives are not getting even 30% votes. So, the issue is not connected with the outer world which conservatives quote a lot in order to safe their face, but even the domestic situation is very much clear and pointing out the usurping of rights of people by the conservatives.
Guess who came to power after the 8 years of Reformist's governance. the same thing will happen again, when people realized what Reformists promised was utter lie and nothing more.
This stubbornness make the conservatives a joke upon which whole world could only laugh. It is same like Ahmadinejad claiming there are no gays in Iran.
Yeah, Conservatives were so weak that Rouhani was thinking it's better to not participate for another round!
In UK, all defence deals are made by the prime minister. Is it possible in Iran?
In UK, if the parliament passes a legislation, then queen is no one to reject it. While in Iran leader has all the powers to reject any legislation or bill in name of being the representative of Allah.
So what?
Even without the written constitution, their system is able to provide the rights of people many folds better than the written constitution of Iran where Wali Faqih becomes above the people's choice and right and gets the eternal power to impose his system upon the Iranian people.
these are some of the British dictator authorities:
remove or appoint the prime minister or any other minister,
choosing all members of the house of Lords (poor commons, such a barbaric naming)
disbanding the parliament,
should approve and sign all of the government and parliament bills,
disband of Australia parliament and governor!!! and the rest of colonies.
approve or cancelling of U.K international agreements.
all laws are applied under her name.
has the full control of army, they are even called Royal army to make sure no one would forget who is the boss!
approving of the foreign policies.
appoints the highest judiciary authority and approves all judiciary laws.
even appoints the highest cleric in U.K
ownership of all national resources, even animals in the parks, ownership of all museums and historical heritages.
THIS IS AN ABSOLUTE DICTATORSHIP.
Iranian have voted to this Islamic Republic system, but I know you can't understand the meaning of vote or democracy.
