Just when youse thinks youse may have grasped the Shia - Sunni nature of a Syrian civil war, comes the Kurds!
In case you don't know it, the Kurds constitute the largest minority group in Syria (around 10% of the population.) They are rountinely harassed by Assad and his allewites. They don't want an Islamic Republic of Syria with Sharria laws. They are NOT jihadists.
The Kurds have successfully established an Autonomous Region in Mesopotamia. The Turks fear the rise of the Kurds since much of Eastern Turkey is inhabited by independence-minded Turkish Kurds.
Kurdistan Reborn is what the Kurds want! Turkish Kurds, Iranian Kurds, Syrian Kurds, Mesopotamian Kurds, and Kurds from various former Soviet Republics want their own NATION. All IMHO.
