This could be a good thing. It will allow for the PKK to be completely legitimate in the eyes of the western world and could very well ensure another KRG in Rojava and eventually one in Bakur. Also, PKK will never fully disarm, If anything a majority of them will simply call themselves PJAK and sit still in Qandil.
This isn't a defeat but a victory for us. Turkey has finally admitted that it will never be able to defeat the PKK. With a move like this, we can enter real politics in Turkey and start taking real steps towards gaining our rights.
