Foreign Policy Achievements & the Tripartite Iraqi Struggle

In an interesting demonstration of unintended consequences or Machiavellian manipulation of the American public (rendered easy by a decades-old, thoroughly entrenched government educational system), the diplomatic efforts of the current administration in engaging those formerly considered our enemies -- inc. Iran, the Taliban, al Qaeda, China, & N Korea -- has w/ remarkable effectiveness forged new alliances among our former allies -- i.e., Saudi Arabia, Israel, Turkey, Kurdistan, Japan, S Korea, the Philippines, and other non-Communist SE Asian countries. In particular interest to me now is what is happening somewhat behind the scenes in Iraq as most headlines seem to be consumed w/ the struggle near Bagdad betw. ISIS & the Shiite al-Maliki gov't. Turkey has mended a lot of fences w/ the Kurds as noted in this article. While I have yet to learn enough about the situation to be confident in my speculation, I somewhat disagree w/ the article in this respect: the Kurd(s) quoted disavow any interest in retaking the first major conquest of ISIS (Mosul); however, I think as this Sunni/Shia war grows long in the tooth & ISIS begins to exhaust their strength, their ability to guard their Northern holdings will wane & Kurdistan (perhaps w/ Turkey's help) will see an opportunity to take advantage of that to take Mosul.
