Here is the full picture of what is going on. I say this not just as an analyst but also as someone from that area.
Turkey's operation is very limited geographically, to the areas near the Turkish borders.
The Kurds still have almost the entirety of three Syrian provinces under their control. And I'm convinced this will make the US stay even longer now.
The local population generally preferred them over areas controlled by Assad, or the rebels in the north.
Even the areas under rebel control might be a price that Turkey will eventually pay for Russia’s support; and igniting the largely/temporarily-abated civil war in Syria.
That forced it to reverse stance against Assad in 2016 & to align with Russia.
The rest is just noise, and those have no desire to engage in discussions to push things forward or prevent the worst from happening.
