re: What is the source of your assertion that...
From the piece you linked: "The PKK has had bases on Qindil Mountain since 1985. This vast area, which is difficult to access, has a long history of providing refuge for armed Kurds."
I agree that the people in the piece, whose village was destroyed by Turkish artillery, are not friendly with PKK. I also agree that the Iraqi Kurdish authorities do not want trouble with Turkey. Still, I think that the Iraqi Kurds feel sympathy and kinship toward the Kurds in Turkey.
Also note that PKK does not represent the Kurds in Turkey. They are only the premier militant group. I doubt that most Kurds in Turkey support them, either.
