I'm starting get far removed from any special knowledge about the Turkish Government's position vis-a-vis the Kurds and Iraq. It's been almost three years since I worked for Turkey so I am now into the game of speculation.
While I was there I always sensed a great deal of paranoia on the part of Turks towards the Kurds. The PKK committed some pretty despicable acts, but for the most part the Kurds have belnded into Turkish society (albeit forced assimiliation).
My guess is that Turkey now sees once and for all the opportunity to END this problem. The war with the PKK has cost Turkey an estimated $80 billion (old figures) and an estimated 70,000 lives in the ten year conflict. Turkey si burdened with thousands of refugees (Kurds) who flooded inot the three Turkish provinces along the Iraqi border -- all fleeing the post 1991 war. Refugee camps are always rife with potential uprising, so Turkey, no doubt, wants to settle this issue.
I do not know if Turkey plans to move all the Kurds back across the border in a post-war Iraq. I suspect Turkey would be in favor of carving out a Kurdish State in Northern Iraq (but I don't know this for a fact). If US leaders do not use this opportunity (assuming victory in Iraq) to create a Kurdish State, then that will be yet another horrensous example of short-sightedness that will create inevitable conflicts in years ahead.
If I were advising the Turks, I'd pretty much advise them to continue what they are doing. Drive the Kurds out of Southwestern Turkey and back into Northern Iraq (and allow for the free passage of refugees) -- then assist in humanitarian aid during the resettlement process.
