The PKK is a terrorist organization, and there is no excuse for the regional government of Kurdistan to allow them to operate in their sphere of influence. The majority of Kurds do not support their methods, as they often find themselves included in the violence.
So, it is only because the Kurds openly support the PKKs goal of a unified Kurdistan, pulling in parts of Turkey, Syria, and Iran into the Iraqi section, that the PKK find themselves able to operate with impunity.. killing Turkish soldiers and innocent civilians.. then blending back in with the Kurds, just as the Iraqi terrorists blend in with Iraqi citizens too afraid of reprisals to protest.
I support the government of Turkey in their effort to remove a terrorist threat to their citizens. It is the exact same decision that led us to invade Afghanistan and Iraq. Perhaps the Kurds will see reason once they understand that no democratic government is going to allow an active terrorist enemy to destroy them.

Personally I'd like to see Kurds get their own country. It's an accident of history that they don't have one already. But the PKK are just terrorists, pure and simple.
