In 20 years, there will be a great transition in fossil fuels from liquid to gas. Iran, as a matter of fact, has one of the word's largest known resources of natural gas that comes only second to Russia. So if anything, they will have a stronger position in the energy market. Unlike Arabs, they are also investing good part of the oil maney in expanding higher education, research, and development. They have 2 million college grads a year. These socioeconomic forces will push the current establishment in Iran into one that is more free, perhaps democratic, less religious, and more progmatic. By then Mullahs are gone or at least gone through a serious metamorphism, and the doors to trade with the world will open once again,. To be honest with you, 20 years from now, a new era of Persian empire could be in the horizon.
