|Iraqi Dictator Saddam Hussein|
I'm not sure Iraq was ever originally set up to be a successful independent country. It was set up by the United Kingdom as a British colony. And the way the British set it up was to create a state where you had to large ethnic groups. Iraqi Arabs and Iraqi Kurds and two major Islamic factions. The Sunnis and the Shias. With a bunch of other ethnic minorities like the Turkmen's and Assyrians. Iraq, similar to Iran, were set up to become reliable sources for oil and gas for Europe especially the United Kingdom. Unlike the State of Israel that was put together so the Jews could have their own country and not have to worry about being murdered by their own government in another country.
But even pre-2003 Iraq War, you could argue that Saddam Hussein destroyed Iraq. Here he had a fairly large country in land, but with only twenty-five-million people or so and yet most of them are educated, that is not only energy independent, but is one of the largest oil and has producers in the world. And yet he created a third-world country. Because he wasn't interested in developing his country. But holding onto and expanding his dictatorship. And invading countries he thought he could control and steal their energy. Iran and Kuwait, come to mind real fast. So Iraq failed, because it wasn't set up to succeed by the British and Saddam, destroys his country by the way he mismanaged the economy started wars that shouldn't have been fought.
