Per the NYT:
The once libertine oil port of Basra, 350 miles south of the capital and far from the insurgency raging in much of Iraq, is steadily being transformed into a mini-theocracy under Shiite rule. There is perhaps no better indication of the possible flash points in a Shiite-dominated Iraq, because the political parties that hold sway here also wield significant influence in the central government in Baghdad and are backed by the country's top clerics.
Efforts to impose strict Shiite religious rule across Iraq would almost certainly spur resistance from Sunni Arabs and the more secular Kurds. But here in Basra, the changes have accelerated since the January elections, which enabled religious parties to put more radical politicians into office.
Small parties with names like God's Vengeance and Master of Martyrs have emerged. They work under the umbrella of more established Shiite groups, but many Iraqis suspect them of being agents of the Iranian government. One of the leading parties was formed in Iran by an Iraqi cleric living in exile during the reign of Saddam Hussein.
The growing ties with Iran are evident. Posters of Ayatollah Ruhollah Khomeini, the leader of the 1979 Iranian revolution, are plastered along streets and even at the provincial government center.
One store is bombed for selling musical instruments and women are harrassed if they dare to walk outside in clothes deemed "improper."
Is this what our soldiers are dying for?
