Don't you feel stupid after acting so cocky?
Turkey wants to fly over Syria. Why would Turkey use aircraft to bomb targets in Iraq but only use short range artillery in Syria? The answer is because Turkey does fear getting its aircraft shot down over Syria. Recently a Turkish Super Cobra (supposedly equipment with EW system) was blown to pieces by an old Igla fired by Kurds. Before that a Turkish F-4 was shot down by a Pantsir.
Russia already has Pantsirs and S-300 in Syria as well as other air defense systems, including the most powerful air defense system in the world, the S-400.
If old MANPADs can destroy Turkish aircraft then S-400s, S-300s, Pantsirs, SU-30s and SU-35s would have no problems. so yes Turkey is afraid, it's not just me blowing hot air it's Turkey's actions that prove it.
