Oil in Iran

It was amazing to me that Iran has the second or third largest oil reserve in the world. That reserve is about ten percent of the worlds oil, but that is the only thing that Iran's economy is based on. Iran exports the oil because it does not have any domestic refineries and that is putting Iran into turmoil. It is sad because Iran has the possibility of being a superpower, but it lacks a few links in the chain when it comes to uniting the nation in order to do so.
