In my younger years, I personally thought that Iraq would be the spearhead of the Arab world. It was the most advanced Arab country with one of the most educated populations and highest living standards in the world (at the time), also benefitting from its incredibly rich history, critical geographic position and influence in the region, a few minor inconveniences due to dictatorship aside. In my mind, the latter would eventually be ironed out, given enough time. After all, Rome wasn't built in one day.
It all went to shit when Saddam Hussein decided to invade Iran in 1980. From there on, there was no coming back. I've never seen in my lifetime a "thirld world" country with so much potential taking the irredeemable path of self-destruction because of the futile ambitions of a man intoxicated by his own self-aggrandizing legend.
