Turkey is strait-up annexing northern Syria. Up to this point, the Euphrates has been a defacto red-line for the Kurds, so giving up land to the east is going to be a tough sell. West of the Euphrates might be a lost cause. Turkey will do anything to prevent establishment of a Kurdish state, even if they eventually have to annex all of Rojava.
“Turkey is strait-up annexing northern Syria.”
Displacing the local population in Afrin and importing Sunni jihadis stacks the decks demographically for any future referendum to unite with Turkey.
The nearby Turkish port of Iskenderun was historically part of Syria, until Turkey engineered a stacked referendum in 1939.
Not going to happen. For many reason. Not the least of it, the Kurds.
