Assad genocidal regime will almost certanly test Turkey on Idlib front after Da'ara emboldend by recent gains. Maybe they even be foolish enough to target some TAFs outposts. That would be a mistake on their part I think. As anonymus US general said back tgen when Turkey shot done russian jet, You dont want to **** with Turks.
I think that recent raid in Latakia by rebels who neutralized about 100 Assadist in Mount Turkman in Latakia was pne of the warnings, one of the factions who participated giving artillery support was 2nd Coastal divison of FSA closly linked with Turkey. Turkish army not just that has capacity to retaliate byitself, by bombing the shit out of regime baes from Aleppo to Damascus, but also can give green light and support to idlib rebels who are the most battle hardent rebel forces in Syria to wreak havoc on multiple fronts...
Also, worth mentioning that in NATO summit these days, NATO in its statments about Turkey underlined its monitoring of balistic threat from Syria and will consider it to be a threat to NATO security - I think its connected to posible confrontation with Assad regime as a way of sending a msg...
Its just my humble opinion based on my interepretation of events and infoormation.. I of course could be wrong.
