All evidence recently seems to point to the idea that
a major deal has already been reached between Russia and Turkey regarding Syria. Otherwise, either Turkey would not be so brazen, or Russia would not be so agreeable. Despite the weight of the Turkish move, all that Russia expressed is "concern" - which is not even the same thing as opposition, let alone strong opposition that we could expect. "Concern" is the bare minimum and the formality they simply
had to express given the situation, but nothing else followed. Instead, just yesterday Russia began to lift its sanctions on Turkey which it imposed last year over the downing of the Russian jet in Lattakia. Of course those "sanctions" are of a purely symbolical nature - which makes it all the more striking that Russia would choose to remove them now. I think it's safe to say that it wouldn't be doing so if it was even a little bit upset at the Turkish behavior. Now Putin is apparently also planning to visit Antalya in a couple of days for a friendly match and conversation with Erdogan. And here's what Lavrov had to say today about the Turkish conflict with YPG:
"Lavrov said it was unacceptable to use the Kurds (who seek to establish a state of their own) to break up Syria, while Kerry pointed out that the U.S. had been working with the Kurdish forces "on a very limited basis". Against the backdrop of the military operation that Turkey launched this week in northern Syria, [...] the two ministers' statements look like support for Turkey, experts note." I think the signal is pretty clear: Russia is in agreement with what Turkey is doing.
If Russia and Turkey were not in agreement on this, I'd expect Russia by now to be calling up UNSC meetings to condemn the Turkish invasion, imposing further sanctions on Turkey, deploying more assets to the Middle East, and most of all - arming and supporting the YPG/SDF with everything Russia has to offer in attempt to make the Turkish adventure as painful as possible. Obviously that's not what we're seeing right now.
But since what Turkey is doing seems to empower the Turkish-backed rebels at the expense of ISIS and YPG (mostly YPG really), Turkey
must have offered something to Russia as compensation. But the only thing Turkey could really offer Russia, and the only thing that Russia would really want from Turkey at this point, is for the latter to cease its support for the Idlib agglomeration. This kind of agreement between Turkey and Russia would make sense for both. Turkey ceases its support for the Al Qaeda emirate while Russia ceases its support for the PKK federation - and the two allow each other to hammer their respective enemies without interference from the other.
With this context in mind, the Kurdish behavior in Hassakah also becomes entirely explainable. They understood that they were going to be sold out as an expendable trading chip, and they acted preemptively to solidify their position. Anyone would have done the same in their situation. As far as Idlib goes - on the military side it is not yet apparent that Turkey is selling out the Idlib rebels, on the contrary, just today they managed to capture a significant village in North Hama. But diplomatically all signs are pointing in that direction.
I think that the further Turkish-backed rebels advance in North Syria, the more likely we are to see serious problems start so emerge for the rebels in Idlib.For Turkey the trade would even make sense from the military standpoint, because it is obviously not interested in occupying North Syria with its own forces. It needs the Syrian rebels to do the majority of the fighting, policing, and administration on its behalf - while Turkey just provides support, the same way that Russia, for example, provides support for the Syrian loyalists. But Turkey can't just pull more Syrian rebels out of a magic hat - if it could do that, it would have done that. If Turkey needs more Syrian rebels for North Aleppo, they will have to be drawn from other fronts, or more specifically from the Idlib fronts. So Turkey is probably going to start encouraging its proxies and puppets to leave the Idlib agglomeration and relocate to North Aleppo shortly, thus also leaving the Idlib area squarely in the hands of the Al-Qaeda alliance, diplomatically and militarily isolated. Which, by the way, may finally allow the US to start its own campaign against Al Qaeda as well.
Speaking of which:
http://www.aljazeera.com/news/2016/08/russia-close-reaching-syria-peace-agreement-160827041830873.htmlThough to be honest, if Turkey sells out Idlib and al Nusra, would Russia even want the US to come in and start bombing Idlib at that point? It would look pathetic - Russia had been bombing the Idlib rebels for a year to little effect, then the US starts bombing and suddenly the whole agglomeration inexplicably starts collapsing. Yay, another easy victory for captain America. This would not be a good PR for the Russian military. On the other hand, obviously the American intervention against Nusra would have many advantages for Russia as well. I guess it all depends on what exactly the US asks for in return.
