The post is referring to leftists who supported Assad because he was backed by Russia and Russia is hostile to the West.
Enemy (Russia/Assad) of our (tankies) enemy (the west)
Edit: I should say that I'm taking specifically about what the post has to say in regards to Ukraine. IDK that there are many tankies out here supporting Israel.
Yes he fucking is, as is every bourgeois politician, including putin. And don't forget the gratitude HTS expressed towards the Zionists. The Syrian revolution had an immense progressive potential in 2011-13 but nowadays I'm just glad the war is over but at the same time I'm concerned about what happens next to Kurds, since HTS also had a substantial backing from the genocidal irredentist Ankara government.
