There’s two groups of Kurds... one group are die hard communists, the PKK, the ones that plague Turkey. The PKK was also in Iraq, but are not the ones we worked with and the PKK has had no qualms about attacking anticommunist Kurds in addition to Turks.
Hopefully the Turks are going after the PKK.
Mullah Krekar of the terrorist group that merged with Zarqawi and which was used by Saddam Hussein to assassinate Kurdish leaders before the war that were friendly to the US was/is a Kurd. The merged group became al Qaeda in Iraq, then ISIS. So not all Kurds are good.
Kurd Mullah Krekar... involved in European terror attacks too... Italy even wanted him for involvement with terror cells there:

Hopefully the Turks are going after the PKK.

That’s not the Kurds the Turks are going after. They are going after the Kurds who were our foot soldiers in the defeat of ISIS. The Turks will ethnically cleanse these Kurds and replace them with their Islamist Arab allies.
