On the surface, it makes sense and sounds like a splendid idea. European colonialism resulted in the carving out of some truly artificial nations, and Iraq was one of them. However, the disintegration of Iraq into three states will not lead to stability anytime soon. In fact, given the complex web of the situation, it might make matters worse. Nothing will anger the Turks, and even the Iranians, more than an independent Kurdistan. With both nations having to contend with their own bands of Kurdish separatists, don't think they won't view a newly established Kurdistan as a threat to be dealt with, and then there goes your hope for a stable Mesopotamia.
