Turkey mainly, Iraq and the Kurds (2006-2014)

[Jedburgh]

If you have a local library that carries Jane's Intelligence Review, they have had a number of good pieces on that conflict over the years. You can also run a search at the Jamestown Foundation's website for "PKK" and you'll get a number of articles that you can sift through. And Human Rights Watch has published a few papers over the past two decades on issues of Kurdish displacement, war crimes, and language rights. Just select Turkey on their publications menu and scroll back through the years.

From more of a political POV, Gunter's The Kurds and the Future of Turkey, Olson's The Kurdish Nationalist Movement in the 1990s and Barkey & Fuller's Turkey's Kurdish Question are useful.

A very good read providing the POV of the individual Turkish soldier during the height of the conflict in the '90s, which was eventually banned in Turkey, is Mehmedin Kitabi: Güneydoğu'da Savaşmış Askerler Anlatıyor. Unfortunately, I'm not aware of an English edition.

Finally, here's a few links to papers you may find of interest:

UNESCO, 2002: The Decline of PKK and the Viability of a One-state Solution in Turkey

U of Helsinki Dissertation, Sep 02: The Invisible War in North Kurdistan

CSIS, 31 Oct 07: Turkey’s Military Options for Dealing with the PKK: A Preliminary Assessment

GeoForum, May 08: Environmental Destruction as a Counterinsurgency Strategy in the Kurdistan region of Turkey

NPS Thesis, June 08: Turkey and PKK Terrorism

But the literature is sparse; it certainly deserves a much more thorough study than what is currently available.
