I recall that it is the Kurdish PKK Marxist terrorists that threaten Turkey not the KRG -- starting in the 1980s and continuing to the present.
The article seems to have failed to distinguish between the KRG and the PKK.
This is little more detailed: Turkey Cozies Up to the KRG and even states "In contrast to the increasing tensions between Ankara and Baghdad following the U.S. withdrawal last December, Turkeys relations with the KRG are flourishing. Massoud Barzani, the head of the Kurdistan Regional Government, was given a red-carpet welcome last month in Turkey when he met with President Abdullah Gul, Prime Minister Erdogan and Foreign Minister Ahmet Davutoglu. Barzani reciprocated the warmth by highlighting the common position of Turkey and the KRG on Syria and signaling to the PKK that if it 'goes ahead with weapons, it will bear the consequences.'"
