I agree with you in all you said.
And while the SDF and its allies in the specific Kurdish organizations have been the greatest hinderance to ISIS in Syria, Erodogan and his hinderance of the Kurds has consequentially been ISIS greatest ally.
Erdogan’s attacks in Syria have zero to do with terrorism in the region and 100% to do with his fundamentalist Islamic goals and his desire to prevent the uniting of all the Kurds in any way whatsoever.
The Kurds who deserved political autonomy the most were the least considered by the powers that divided up the former Ottoman Empire, and they were feared the most by Turkish nationalism that didn’t seek to merely protect the Turks of the Ottoman Empire but continued Turkish domination of as much of the old Empire as they could, in spite of and regardless of the sizeable groups of non-Turks in the area that the Turks sought their dominance in. The losers were the Greeks, Armenians, Kurds and others in and ajoining Anatolia.
The Kurdish model for the future should be for a Kurdish declaration of a constitution much like Israel - a Kurdistan that is the declared homeland of the Kurish people, while simulatenously a secular democratic state with equal rights, including religious and political rights, for all citizens within it.
