Should have send suicide drones like kargi or those from stm.The way you have good relations with Russia is to not take any of their shit. Russians are your typical playground bully, if they can harass you they will but if they know you will kick their arse should they do something to you, they become your best friend. Underlying the Russian façade as witnessed by the Ukraine war especially seeing them flee from conscription is a cowardly character.
For me its not about having bad relations with Russia, its about limiting our economic exposure to them so that when we need to hit them and we do, it limits what they can do back. Militarily speaking there is very little they can do.
Also they are not going to nuke a country where they make billions of dollars from and then risk that nation shutting them down in the entire region. Turks don't seem to understand that at the end of the day the YPG/PKK is a just a dirty terrorist organisation that brings no profit to these powers except for its ability to be used.
Russia is the weak link in Syria, it can be broken and should be broken.
However since the jet downing we did the dumbest thing you could do, we deepened energy ties with Russia. Energy being Russia's trump card and energy dependence being our biggest weakness. Putin must be laughing at erdogan.
Like wise the attacks on Turkish controlled regions has to have a cost, send Ukraine Akinci and make a big advertisement about it. And each time the Russians disrespect you keep uping the support.
Send them anti drones system as well by aselsan.
