Kurds are for Kurds. They hate both types of Arabs (ISIS or Alawites). Just because they are fighting ISIS does NOT mean they love Alawaite Arabs. Heck, they do not even like their fellow Iranians in Persians. They absolutely hate the Turks, as well.
All other major ethnicity in the Middle East have their country except for the Kurds. Kurdistan would include half of Turkey, half of Syria, half of Iraq and half of Iran.
