re: "Undeclared Civil War raging for more than a year..."
Michael Yon is heading back to Iraq. He's calling it a civil war, and if Michael Yon thinks it is, he's got my attention.
Doesn't change what needs to be done, though.
You're absolutely right about Sadr. I predict major violence from his outfit when the Shiites lose some of their power in the government, and suspect he's responsible for much of what's going on now.
