NATO is becoming really a thorn in the side for all its members. Turks are nearly on the verge of war on Iraqi Kurds despite American anger. Americans are supportive of them. Should we expect Turks will fight Americans to subdue those damned Kurds? How do you like that kind of partnership? Sadly enough, there has been another precedent of the kind when back into 2003 Turkey refused the USA troops to deploy through its territory to Iraq in Operation Iraqi Freedom
Definitely, Turks are irritated by the fact that USA have got their own agenda in Iraq separately from that of NATO one and Turkish position as well.  Generally support for NATO in Turkey declined from 53% in 2004 to 44% in 2007. That’s really a challenge! I know that some Turkish military see NATO as tool to serve mostly interests of USA and Europe. Well, Americans added meat to it when started supporting Iraqi Kurds, Turkish sworn enemy. Ankara thinks now that USA have undermined the spirit of NATO where all members are partners. The latest rumor among the military is that Turkey will suggest vital changes in NATO at some extraordinary meeting of the alliance. High time imo.
