I would be surprised if Turkey needs to worry about any PKK at this point. I am sure they are worried about their northern Iraqi towns as is the Peshmerga. The Peshmerga forces are able to conduct combat. They have resources. I am sure they would welcome any consultations and supplies Turkey might have in mind. The Peshmerga can be instrumental in assisting with any return of the PKK as trouble to Turkish citizens. At this point the circumstances make for unexpected allies and outcomes for peace in the region.
