Iran has huge deposits of oil and petrolium. It is there #1 export and source of money for the state of Iran. Nuclear energy is cleaner, greener, and more efficient then using gas/oil. They have the right to pursue this technology. Now on the other hand the way they are going about it is wrong. You could say they have a case of short man complex. In no way, do they want to be told what they can or cant do. They refuse to listen to concerns of the international community resulting in a stand-off. The international community just wants assurance that Nukes cant be built and Iran is not giving them that. Irans economy is suffering huge inflation. Oil exports could help them economically. It's a shame they being stubborn. Probably gonna get secretly air attacked in no more then 6 months.
