I wonder why our Russophile comrades didn't mention this development?
Very simple, I waited before the situation becomes more clear, but it isn't clear even today if the way can be used to transfer any goods or not. The whole way is under fire control, and up to now remains under fire control. But what this fire control really means is not easy to establish from outside.
There have been some three or so trucks with tomatoes or so presented to some Western media, the other side has named them faked. So, if it is possible to transfer weapons to the terrorists inside is not clear, the reasonable guess is that it is possible, but with serious losses on the way. During the last days, the situation became even worse for the terrorists, because the Syrian army has taken a hill which gives fire control over a much longer part of the path. And now the terrorists are attacking this hill all the time to take it back, to make at least some part of the way safe, up to now without success.
It looks like the Syrian army is not that uncomfortable with this situation, given that the terrorists have to defend an area which can be heavily bombed without causing any civilian causalities (most of it is a military academy), so that the terrorist loose, and have to loose, a lot of fighters, do not gain much, given that the whole path is under fire control, but cannot simply give up this deadly place, because this would be the final fail in Aleppo, and Aleppo is central. In fact, they even have to attack, to reach a safe, stable situation - but to attack in well-known places.
So far about Aleppo. What the Turks do and want to do in the North is not clear at all, but, given that the "protests" from Syrian and Russian side against this obvious violation of Syrian territory are formulated in a quite mild way, behind this may be some inofficial agreements with the Russians/Syrians that the Turks are free to hit the Kurds, in exchange for something yet unknown. I have read some claims that some terrorists run away from Aleppo to go to Jarablus "because they pay much more there". What the Turks want is to prevent a Kurdish state. Syria does not want such a state too. So, why not allowing the Turks to destroy the Kurds? Given that a Kurdish state would be an US vassal state, Russia is not interested in such a Kurdish state too, the Iranians have a problem with Kurds too, so will cooperate too. So, in principle there may be a Turkish/Iranian/Russian/Syrian coalition against the Kurds supported by the US. And the US support actually looks quite weak, the Kurds will have to learn the lecture of all the US vassals, that they are only a tool, to be thrown away if other interests are more important. The other interest of the US is now to prevent the Turks from leaving NATO.
But all this in a situation where nobody trusts Erdogan.
The other important news is Darayya. This is a suburb of Damaskus, and there have been small but steady progress of the Syrian army during the last weeks. And it seems this progress has reached a critical limit, and the defenders of Darayya are giving up. So, there are negotiations, some claims that the negotiations have already been finished successfully, other claims they are yet ongoing, with the aim that some of the locals can use the amnesty by laying down their weapons, others will be transferred, by UN or so, to Idlib or so.
This will free, of course, a lot of soldiers now encircling Darayya, which will probably be used in East Ghouta. In this region, the Syrian army advances too:
These advances endanger even two regions with encirclement: The Northern part, where the terrorists hold an important hill, Tal Kurdi, which has, itself, a very good defense, and allows to control a lot around. So, to encircle it seems a good idea, and the latest advantages have been in this direction, with taking an Army base. And there is the South Eastern part, which is endangered too.
