Turkey’s invasion of Syria’s Afrin District has mostly been about Turkey fighting against the Kurdish YPG, and also the possibility of a fight between Turkey and the US. Somehow, the Syrian government was forgotten on this.

Syria, US-Backed Kurds Have Mutual Interest in Stopping Turkey
But they were watching the invasion, and have been quietly sending support to the YPG, reflecting the obvious mutual interest in keeping Turkey from expanding its presence in Syria.
Turkey, after all, has long since ended its historic ties to Syria’s government, and has been giving all territory it seizes to Syrian rebel factions. The YPG controls some 25% of Syria, and Syria clearly doesn’t want that all falling to the rebel.
This puts both Syria and the US in a tough situation, as they’re both allied with the Kurds, but both severely at odds with one another, with Syria saying US troops are unwelcome, and the US coming off of killing over 100 pro-government fighters last week.
