Bill --they have reached that point---actually the ISF has been unable to retake Tikrit and has begun to build a defensive line along the Sunni/Shia regional divide lines and the Kurds are voicing even stronger the words "independent state" and the Turks are "non publicly" stating the same thing.
One really needs to step back and seriously relook the IS/Sunni coalition strategy---it has been massively well implemented vs the total lack of a US strategy.
