Here is the Iraq 3 state solution in brief:
1. ISIS becomes he first true terrorist state with unbridled ambitions to expand and more and more funds to do it.
2. The Kurds get annexed by Turkey for the oil fields. Not immediately but over time this is certain.
3. The Shi’a state comes under the umbrella of Iran and rather quickly is brought into the Iranian fold.
And none of this solves the problems inherent in Iraq today, it only exacerbates the problems.
Did I mention the ethnic cleansing that would be even worse then than now or the economic upheaval in Sunni areas leading to cross border war in perpetuity?
