Liberate the Kurds and the Sunnis in Iraq & Syria

Its time to admit that the multicultural (Kurd, Shia, Sunni) utopia with a Shia majority did not work for Iraq and tell the Kurds and Sunnis that they can have independence from Baghdad, if they want it, provided ISIS is defeated.  This would provide the much needed motivation for the Sunnis to fight ISIS. This would also be a good lesson for the central government in Baghdad.
