A Turkish newspaper report, which opens with:
Terrorist Kurdistan Workers' Party (PKK) leader Abdullah calan stated that the era of armed struggle to achieve the political goals of the Kurds is over. He was speaking in a meeting with two Kurdish lawmakers, who made rare a visit to the PKK leader, being held on an island prison, on Thursday, signaling that Turkey is negotiating with the terrorist organization over ending a conflict that has killed tens of thousands over the past three decades.
Ocalan in jail since 1999 has power:
his order, made after a visit from his brother, to end a 68-day hunger strike by PKK terrorists in prisons across Turkey was immediately obeyed.

It is curious that an imprisoned leader can make such decisions. How a nation and its opponents in an insurgency / terrorist campaign use law enforcement, with imprisonment, as a tactic to get results is an perplexing question. It took a long time for the UK to think through a LE approach in Northern Ireland, even then it took PIRA just as long. Both Italy and Spain have used the tactic with great effect, but is little understood or documented IMO in English.
