I wonder if these "air defense systems" will all be implemented purely in Syria, or if any of this weaponry should happen to "accidentally" slip into the border of Iran? Or possibly even Hezbollah? Russia shows when it comes to WW3, it has no problem supplying the arms and sit back to watch how things play out AFTER it already made it's arms-deal profits... If anyone thinks all these systems will stay only within Syria's borders they're crazy.
