I wonder if Iran will join Russia in teaching turkey a lesson? Im sure the Russians are keeping tabs, and will be giving some new toys to the PKK.. But im not sure if Iran would follow. Since it has a strict "no pissing in your own pool" policy when it comes to neighbour instability. time will tell, But the Turks are crossing lines.
Regardless though, Turkey should expect some nasty surprised going forward... Especially their illegal occupying troops/terrorists in northern syria. Russia has alot of tools in its hands to make the turks bleed. Maybe Erdogan might get on his knees again and apologize again publicly?
