Russia is now flying new S-400 systems into Syria instead of using surplus S-300 systems. Russia means business and both Turkey and Israel had better understand the message Russia is sending loud and clear - do NOT attack Syria or the Russian army defending Syria. The ONLY thing more deadly than a Russian S-400 is the Chinese/Iranian clone.While Ynet keyboard generals will ignore the Russian message, the real IDF leadership has just seen their whole world change for the worse. Israel and Turkey can no longer fly even in their own air space with out being targeted by the Russian S-400 systems.
