Islamic Law for Governance?

Many writers have argued that what happened in Iran cannot be reversed. Amir Taheri suggests the creation of a new imamate.

The fight for Iran’s future is far from over Amir Taheri - Times Online: "The new system that seems to be emerging in Iran appears to be modelled on two Islamic states of recent times."

What is interesting with the article is that Taheri seems to suggest that Iran cannot be ruled only with force of the Iranian Republican Guard Corps military dictatorship. They need further legitimization. They need an ideology as well.

Based on the other Iran that Taheri spoke of last time, I would like to ask if this Iran really buys in on that kind of religious legitimization. That the rurals in Afghanistan on their educational level does might not be that surprising but the other Iran is rather educated. Ahmadinejad's supporters might buy it. Isn't the problem right now that a religious legitimization and a constitution based on sharia does not function for a modern state today? The other Iran demands a government that can bring them out of a global economic crisis.

It would be of considerable interest to discuss the fact that sharia is not suitable for governing a modern European state, based on the failure of the Islamic Republic, since there are more and more demands for the use of sharia instead of the Western Law in for example Great Britain.
