Iran is not Arab. OK, you already knew this, but it’s worth remembering when looking for likely alliances in the region.
Iran is an ancient nation. The Persian civilisation is 6000 years old and hasn’t attacked another nation for hundreds. Its borders are among the most stable on the planet. Its people are very proud of all this.
Iran’s economy is not centrally-run. It’s an Islamic Republic, not a People’s Republic. Wealthy kids in Iran drive to the mall in their Lamborghinis and take cocaine. Working people struggle. Poor people die young.
Iran’s infrastructure is shot – nearly three decades of US sanctions mean they don’t have the expertise (or the materials) to build oil refineries. Iran is the largest exporter of natural gas and one of the largest exporters of crude oil in the region but imports nearly half of its petrol from refining states. Iranians hate this dependency.
