Tribes Trump Religion?
Have you ever read this before?
The structure of Iraqi tribes overlaps sectarian divisions in Iraq...Certain powerful tribes in Anbar for example have their largest following among Iraqi Shiites. Shiites and Sunnis can be members of the same tribe and fight under its banner and vow allegiance to the same tribal chieftain regardless of sect.
I think it's news to me (at my age, I can't remember all this stuff), but Azzaman makes it quite understandable. Have a look. He talks about the latest trend in Iraq: ecumenism. Of course you've seen Mike Yon's fabulous photo, right? You haven't? Feast your eyes on it.
And give thanks.
