As a second step, the strategic M4 and M5 highways which link Latakia and Damascus with Aleppo should have been opened to free trade, but with the newest HTS campaign against the Syrian opposition, four different scenarios of the fate of Idlib may occur:
Starting a Turkish military operation into Idlib to clear the area from HTS
Approving a Russian-led military operation by the Assad regime while establishing a humanitarian safe-zone along the Turkish-Syrian border
Rebranding HTS into an acceptable structure
Freezing the dispute over Idlib and gaining time
The first scenario seems to be the most unlikely among the listed.
