1979 was a pivotal year, especially for the Middle East region. It had:
- Egypt-Israel peace treaty
- Iranian Islamic revolution
- Soviet invasion of Afghanistan
- Siege of Mecca
- Saddam becoming Iraqi President
Let us assume none of these things happened. Peace negotiations between Egypt and Israel are torpedoed for whatever reason, the Iranian Revolution either does not happen or it goes differently (no "Islamic Republic"), Soviet leadership decides not to invade Afghanistan, the Siege of Mecca does not happen, and Saddam dies in a plane crash and does not become president of Iraq. What happens for the Middle East, and the world, if all of those things happened?
