Idlib yes Afrin maybe Menbic no. For Afrin we will never capture the city itself because of the tensions coming from the local people. The best we can do there is surround and cut it off by capturing Tal Rifat and the area bordering Idlib. I dont believe we can act in Menbic because Menbic is the operational center of US in the west of Euphrates. Very strategic point with one word. If we capture Menbic that means US losing authority over Eastern Aleppo and possible Euphrates Shield territory. They have very critical assets there as special operation forces that are ready do act when needed. They just cant afford it. If they lose it from where are they going to act without revealing the possible covert operation? The road from Al Thawrah is long enough.Iraq is first for us, DEASH almost finished and we has good relationships with Iran-Russia-Central government of Iraq. US nothing to do at Iraq anymore, thats why we can take many actions over there, when we solve Iraq problem we can focus on Syria i think.
If we wanna be strong at Syria we have to be capture Afrin, Menbic and Idlib then we can be say somethings at the table about PYD otherwise it would be very hard situation for us.
