Apart from confusing East and West, you are completely right. You could also have added India and China to your litany of nuclear states in the proximity of Iran, plus the possibility that Saudi Arabia might also go nuclear. Imagine a pro-Taleban government in Pakistan or Al Quaeda sympathisers seizing power in Saudi. The Shi'ite 'heretics' of Teheran would be at the top of their hit list, right up there with Israel. If you were running Iran , what would you do,particularly when you saw how easy it was to invade non-nuclear Iraq? The problem with the Iranian leadership is not its weaponry but its extreme Islamist ideology and its support for extremist groups such as Hezbollah. If that leadership was overthrown by a more liberal leadership, it too would be tempted to seek nuclear weapons. Those are the facts of life.
