PISSI is fighting with Turkey, which is now sealing the border with the PISSI-controlled areas of Syria.

There were reports that Turkey quietly supported PISSI in the past. If that was true, it seems not to be true any more. The Turkish army is not a joke like the Iraqi army; PISSI will find it a powerful foe. Alas, the long-standing hostility between Turkey and the Kurds makes it unlikely Turkey will give the Syrian and Iraqi Kurds much help against PISSI.
