Iran has a large amount of oil and gas deposits. The developed world is highly dependent in Iranian oil and gas. But Iran has not used this merit to develop its economy for three reasons: 1- Iranian governments did not use it properly, reasonably and economically. They habitually spent it to compensate their current expenses not economical projects and supporting private section of economy. 2- The 8 year war between Iran and Iraq is the second reason. During those years billions of dollars was spent to run the full sterling war. 3- US-based economical sanction is the third reason which highlighted Iranian dependence to oil instead of trade and industry. These three reasons have made Iranian economy sick and weak. The advent of president Ahmadinejad made the situation worse. Because his arrogant view toward the outside world has created more tensions. Recently the UN Security Council has condemned Iran for two times. Also president ahmadinejad did not follow the economical scientific rules. Many Iranian economists protested his plans, but he didn’t consider their advices. The only positive outlook is the extra high price of oil as the result of world economical condition which may save Iranian economy.
