Had the coup never taken place, Khomeini would have remained a little-known cleric. Instead, he was exiled for 14 years, a time during which he cultivated his image from that of a charismatic leader to that of a sacred returning messiah. And during those 14 years, the prospect for the emergence of a truly democratic Iran grew dimmer while Islamic radicalism, associating all that is Western with the hated shah and his supporters--principally the U.S.--took a deeper hold on the passions of an increasingly frustrated younger generation.
Had the coup never taken place, there would not have been a hostage crisis, and neither would the U.S. have severed its relations with Iran and imposed economic sanctions. Both actions, more than 20 years later, remain in effect to this day.
Had the coup never taken place, Saddam Hussein would have never dared invade Iran in September 1980. The U.S. would never have sided with Iraq's dictator and neither would it have committed itself to a policy of ensuring that Iraq not lose the war. It would not have supplied Hussein with crucial assistance or turned a blind eye to his egregious crimes against his people.
Had the coup never taken place, Hussein would not have found himself by the end of the war against Iran as the commander of one of the largest armies in the Middle East.
More important, he would have never been under the impression that, as long as he restricted his aggression to fellow Muslims and kept off Israel, the world would only decry and condemn him but never act.
Had the coup never taken place, chances are that Iraq never would have invaded Kuwait, and the U.S. never would have had to orchestrate a massive military campaign against his army, let alone establish bases on Saudi soil. It would not have rendered talk about human rights and international law totally meaningless and hypocritical to Arab and Muslim ears.
Imagine a new era of foreign policy--an era in which international law is taken seriously, respected, in which sovereign democracies are encouraged, nurtured, applauded, rather than fought against, stifled and killed. Imagine if we abandoned, once and for all the poisonous doctrines of "Iron Chancellor" Bismarck and Henry Kissinger and instead subscribed to those of Amnesty International and Human Rights Watch. Imagine if we took the United Nations and The Hague seriously, rather than treating them as kangaroo courts in which only those causes championed by the mighty and powerful were pursued with vigor, while other grievances were neglected and scorned.
How many millions of lives would we have saved, and how much safer and more prosperous would the world be today?
