 Turkish leader to end this enmity with Turkey's Kurds, ignoring hardline nationalists and opening a dialogue with Abdullah Ocalan, the imprisoned PKK leader.  The idea was to give Kurds in south-east Turkey a measure of self-government and cultural freedom, while drawing Iraqi Kurdistan and the liberated Kurdish cantons of northern Syria into a Sunni Turko-sphere that would serve as a buffer against Iran's Shia axis to the south, which stretches across Iraq and Syria to Lebanon.
