I have been puzzling over the emerging Turko/Russian relationship and in the end have decided that Erdogan and Putin have reached an agreement in which Turkey has a green light from Russia to destroy Kurdish attempts to build an autonomous region in the northeastern wing of Syria so long as Turkey stops supporting FSA/jihadi efforts to bring down the present Syrian government.
I suspect that the Turks will try to cheat on this arrangement through covert support to the rebels west and south of Aleppo but they will have a difficult time doing so under the watchful gaze of the Russian aerospace forces and Russian intelligence.
IMO the Turks will seek to manage their relationship with NATO as a hedge against Russian and Iranian potentials as future threats. The NATO and larger US incomprehension of the perfidy of Erdogan's government will make such an ambiguous duplicity possible.
On the ground the meat grinder attrition battle at SW Aleppo City is going well for R+6. Russian airpower is killing off a great many jihadis, men who must be gone to make the Russian goal of a negotiated peace in which Assad's government remains in place a reality.
The jihadi attack into northern Hama is a problem but one that will prove temporary and yet another opportunity for attritional warfare against the rebels. Unfortunately many civilians will suffer while the effort to re-take lost ground is underway.
It will be interesting to see how large the Russian ground presence at Aleppo City will become.
