The end of Daesh militarily can be envisioned. But unless the Iraqi government becomes more inclusive and politics successfully with Iraqi Sunnis (and spends some of its billions in oil income to rebuild their cities), then radicalization will remain a threat.
Meanwhile, critics of President Obama’s plan, set out 18 months ago– which involved training of Iraqi troops and rebuilding the Iraqi army. and the offer of close air support to them– may have to eat some crow. That is, they may have to if US cable news bothers to notice that out there in the real world, Daesh is facing another major setback, after its losses of Tikrit, the refinery town of Beiji, and the Kurdish area of Sinjar.I suspect part of it is thatmost US journalists are based in Erbil and find it easier to report Kurdish advance, and some of it may be that the Iraqi Army''s Shi‘ite militia allies and IRGC advisers don't fit the preferred narrative. (No one is paying much attention to the Asad regime's successes in Homs, either, though not against ISIS.) But it's a valid point.
