that is not going to happen
on the contrary the reasons they may leave was because assad was on power and if we made it expensive for them now they will stay because it is cheaper to maintain YPG and by the looks of Trump's officials can can guarantee you they will stay
im note sure they will rebel if they have better life under YPG with oil money ( you could have make them rebel via financial and water crisis ) and even if they rebel western media will simply say they are isis and YPG fighting isis
afghanistan is a mountainous country and and Taliban put them on constant pressure via guerilla warfare and they didn't had oil money to reduce the costs it as net dead weight unlike Afghanistan here is flat land they have PKK doing the hard work and now they have even more oil money. beside Kurdistan plays a key role on long term security of israel afghanistan USA didnt had such objectives
With Assad in power in reality there was nothing that could have been done. Even all the talks in the background was that he looking to cut a deal with the USA/Isreal to save his own arse. Had that happened i guarantee a condition would have been autonomy in the north. Had he been brought back into the fold and accepted by the west our position would have become even worse.
We all know Syria was a massive fiasco from day one, AK party played it like fools. But without going over all of it again. Right now the rebels need to reclaim control of the country, then we will see the reality of what's transpired.
If the rebels start accommodating the pkk, basically following greater middle east agenda then we will now 100% that Turkiye has indeed been f'ked. However, if we start seeing movements against the PKK, we start seeing arabs tribes breaking away from them. Then we too will know the outcome.
But whatever happens the americans, russians will do everything they can to protect their pkk state. So if the arabs do move against the PKK, we got to be ready for the americans to attack them and for their media to ramp up the isis narrative again.
