Breh to be honest Russia aint going to do shyt against Nato not right now. It will defeat his entire purpose of protecting Syria at all costs and will allow the rebels to rebuild. Fight two wars brehs with an economy made of shyt
Moscow won't retaliate. They know exactly that NATO would love it if they did.
Here's what I think they'll do.
1) "Technical problems" cutting off natural gas to Turkey. 60% of Turkey's natural gas is imported from...Russia.
2) Spetznaz on delicate missions cracking "rebel" Turkey-paid/weaponized Turkmen, Uzbek, Uyghurs
3) A de facto no-fly zone along the Syrian border with Russian fighters ready to shoot down any Turk intruder at the slightest "mistake".
4) "Discreet" weaponizing of the PKK enabling them to raise appropriate hell all over Anatolia.
