no they won't. they'll argue, shoot, and bomb their way into oblivion.
see, nation-states only form and solidify real good where there is very clear dominance of one group of people. iraq, like lebanon, simply should not be a country.
see many natives americans in seats of power these days (ignore casinos, please)? how are them armenians doing in turkey? anybody ever heard of the ainu in japan?
the best plan for iraq might just be fracture.
and winky don't be worryin' about them shi'ites joining up with iran. soon as we leave they'll start pissing at each other.
