It seems clear to me that the U.S. is arming the Sunnis so that they can overthrow the newly formed government of Iraq. At least that's probably the long term goal. Bush would much rather deal with Sunnis. A Shiite dominated govt. was never what he had planned.

First they'll rid the country of al Qaeda, then they'll revolt against the government, then they'll turn on the Americans.

Hey, we're right back where we started!
