 Passage 3:Turkey had been fighting PKK and other groups in southeastern and eastern Turkey for several decades. The Kurdish–Turkish conflict is estimated to have cost 40,000 lives. The Turkish government has publicly stated that it does not recognize a difference between the Syrian YPG forces and PKK, and says both are terrorist organizations. While the PKK has been designated as a Foreign Terrorist Organization by the United States, the United States' position on the YPG is that it is not a terrorist organization, a stance that has generated much conflict between the two NATO allies. Despite this, the CIA named the PYD as the "Syrian wing" of the PKK in its World Factbook on 23 January 2018. On 14 February, Director of National Intelligence described YPG as the Syrian wing of PKK in its new report.
