“Then maybe Damascus gets some S-500s.”
Russia and Iran are both in Syria. From my porch I can see IAF recon sorties flying over Jordan and Syria, and every once in a while a missile launched at an Iranian or Hizbollah target within Syria or Lebanon. If Assad doesn’t already have S-500s, he’s probably got something better.
You’re well advised to stop viewing the world through your TV screen. It’s a mirage.
...and my advice is you STAY on your porch unless you want someone firing missiles back at you. Syria doesn't have the latest Russian anti-missile tech, but that may change if Israel sticks its nose where it doesn't belong.
