By accident of geography, the world's major oil resources are in Shi'ite-dominated areas. Iran's oil is concentrated right near the gulf, which happens to be an Arab area, not Persian. Khuzestan is Arab, has been loyal to Iran, fought with Iran not Iraq during the Iran-Iraq war. This is a potential source of dissension. I would be amazed if there isn't an attempt going on to stir up secessionist elements in Khuzestan.
Noam ChomskyThere is a narrow class of uses of language where you intend to communicate. Communication refers to an effort to get people to understand what one means. And that, certainly, is one use of language and a social use of it. But I don't think it is the only social use of language. Nor are social uses the only uses of language.
