It appears that the SAA have now officially pushed as far North as Kobani, blocking off any advance by the Turkish moderate headchopping proxies.

This appears to have freed up resources for the SDF (essentially just the Kurds), allowing it to hold off the advance on Ras al-Ayn and recover a bit of ground.

Perhaps an ideal situation for the government in Damascus if both the (formerly US backed) SDF and Turkish backed NSA (National (sic) Syrian Army) bleed resources against one another.

Unfortunately it appears that the US isn't really leaving all of Syria, with At Tanf and it's refugee prison population still occupied, and also the lack of US withdrawal from the key Deir Ezzor oil fields east of the Euphrates.
