Iran is committing the unforgivable sin: allowing payment for its oil in currencies other than dollars. From Gary Richied at mises.org:
Kish, since you are wondering, is an Iranian island in the Persian Gulf famed for its tourist and shopping attractions. It is becoming a serious rival to other nearby vacation hubs in Doha and Dubai.
Along with pristine beaches and extensive malls, Kish is—or rather ought to be—known more widely for another feature and institution which the Iranian mullahs established there way back in 2003; namely, the Kish Bourse (i.e., Kish Stock Exchange). بورس کیش if you prefer the Farsi.
Think of it as the Chicago Mercantile Exchange of Iran, a country stacked with natural resources, a relatively well-educated and sophisticated population (the literacy rate is 97 percent among young adults, which, if you consider the deplorable state of secondary education in the United States, means that Iranian youth are most assuredly smarter than your average young American adult), and an economy burdened by mismanagement of their own Islamic theocracy and crippling, long-duration sanctions from the American secular theocracy.
That American secular theocracy has considered it a dogmatic rite of passage into the state and corporate media (their temples) that one must, at the very least, excuse the economic, cultural, and political warfare against Iran as necessary for a variety of spurious reasons. Who really has enough free time to investigate and then suggest otherwise? After all, Iran is plagued by terroristic Islamic fundamentalists who have pledged—like their former president, Mahmoud Ahmadinejad—“to wipe Israel off the face of the earth.”
