Costly as the dispute over Iranian oil has been to all concerned, the affair may yet be proved worthwhile if lessons are learned from it: Underdeveloped countries with rich resources now have an object lesson in the heavy cost that must be paid by one of their number which goes berserk with fanatical nationalism. It is perhaps too much to hope that Iran's experience will prevent the rise of Mossadeghs in other countries, but that experience may at least strengthen the hands of more reasonable and more far-seeing leaders. In some circles in Great Britain the charge will be pushed that American "imperialism"—in the shape of the American oil firms in the consortium!—has once again elbowed Britain from a historic stronghold.
