The Proof in the Pudding: Iran as the Great Failed Islamic Experiment
When the Islamic revolution started in Iran and established complete Islamic rule in a country that enjoyed all the benefits of revival and progress, such as manpower, ample natural resources with vast quantities of oil at the top of the list, and a civilisation with a history going back thousands of years, people looked to the newly born Islamic revolution as an incisive test of all the contemporary Islamic movements. If it succeeded in establishing the "society of justice, freedom and progress," the other movements would, consequently, acquire a tremendous momentum that would be difficult to stop in any country throughout the Islamic world suffering from backwardness and sinking under the burdens of repressive regimes, and yearning for those voices calling for Islamic rule and application of the Sharia. The decisive test was there in that revolution, which took full control of an Islamic country of great consequence, an ancient history, and a future rich in encouraging potentials.
Nonetheless, the signs of failure manifested repeatedly following this Islamic revolution, year after year, were not echoed at all among the advocates of Islamic rule in the rest of the Arabic and Islamic countries.
