The pending conflict between Iran and US has been making headlines, even more than before, in the past few weeks. Aircraft carriers moving into the Gulf, troop surges, hundreds of Iranians arrested in Iraq and the nuclear standoff had everyone speculating an imminent, inevitable US strike against Iran. Other say, an Israeli strike more likely. But of course everyone knows it isn't that easy, even for the Bush administration.
It has surfaced that US, along with Arab Sunni states afraid of Iranian influence, is supporting separatist movements to destabilize the Iranian regime. A large portion of Iran isn't Persian, there are Arabs in the south-west, Baluchis in the south-east, Kurds in west and Azeris in the north-west, these ethnic groups make up more than 40 percent of the population in Iran, only the Azeris are Shia. None of these are adequately represented in the government and are treated as second class citizens (apart from Azeris again). In the past two years the number of attacks on Iranian security have increased.
So far the situation isn't that worrying for Iran but if the attacks increase and the US, along with Sunni states, decide to push this, it could be disastrous for Iran. Arabs are also becoming more vocal in demanding more rights for Arab-Sunni minority in Iran.
