This is certainly good news on Thanksgiving. I believe that I've read something concerning insurgent groups wanting to lay down their arms before but this piece is a bit more definitve. The tribes in al-Anbar are the ones who have caused the most trouble in Iraq. The article does not distinguish which tribes are in fact involved but I found the comment that they were dealing with Chalabi rather than with Talabani interesting.
Are they anticipating a Chalabi victory on December 15th? Is the "talk" a means to promote Chalabi's party?
This interview with Talabani done in 2002 gives a bit of recent historical perspective to current Iraqi politics. Talabani doesn't seem to hold the CIA (or State) in very high esteem.
He's not alone.
