A partner for negotiation?

According to this article by Al Jazeera, there are 11 insurgency groups that are willing to negotiate with the new Iraqi government. I don't know ultimately what their intentions are, but it is a relief of sorts to see that the insurgency has some order and structure to it. You couldn't hope for much improvement if the insurgency was just hundreds of tiny cells working independently; but larger groups (possibly only 20 or so) can be negotiated with.
