You have to be careful when you say "insurgency." You have to distinguish between the Shiite militias and the actual insurgency, which is the Sunni groups. Most of the Shiite militia activity is not directed at the U.S., it's directed at the Sunnis. The Sunni insurgency, meanwhile, is directed at everyone -- the U.S., the Iraqi government, the militias. The best way to divide it up is into three camps. You have Sunni nationalists, initially a large portion of the insurgency; the moderate Sunni Islamists, who use Islamic terminology and talk about establishing a government based on Sharia law; and you have the Salafists, like the group Al-Qaida in Iraq. To them, the fight is not about preserving the borders of Iraq, it's about revolution, about rebuilding something completely new on the basis of some kind of idyllic Muslim empire.
